Group #33 day 4

A) I believe we will be successful because we have put a lot of time and effort fine tuning our Rube Goldberg so no minor errors will occur.

B) Grant mounted some more rails, Z made the base more sturdy and reliable, Nate covered the loose screws, and I (Cameron) put together the mouse trap and pulleys system to cue the balls launch.

C) Yes, we have fulfilled all of the projects requirements and we have identified all machines and energy transfers.

Group #33 day 5

A) When we presented the project it was not successful. We were unable to get our mouse trap to set and we were unable to release our golf ball.
B) We would for sure need to plan more a head of time and plan our working better.
C) We learned how to use tools better, we learned about angles and measurements, and we learned about doing better for our planning skills.

Group 25- Day 5

A. We were unsuccessful in our official test, but were successful in unofficial tests on our own. We were unsuccessful because our marble got stuck inside of one of the tubes and in between a crevice connecting two ramps.
B. Spend more time connecting tubes and ramps because if not connected properly, the marble is not able to roll smoothly and leads to experimental error.
C. We learned that a pulley does not actually have a mechanical advantage unless it is connected to another pulley. We also learned that it best to draw out a blueprint first to know how to assign projects and time. Lastly, we learned the different placements possible for a fulcrum in a lever.

a) The simple machines we plan to use are levers, screws, pulleys, and incline planes. We will use levers for dominoes to set off a mouse trap and then also to release the golf ball. We will use pulleys to turn on the light and to raise a weight to hit the golf ball down the ramp. We will use screws to hold the golf ball in place. Lastly, we will use incline planes to slow the marble down.

b) The energy transformations we will use are GPE, KE, Chemical to electrical, and then gravitational energy to kinetic. GPE is used when the marble rolled down the planes. Chemical to electrical is used when batteries turned on a light.

c)  Bobby Buell made the lever for the marble and contributed during his free periods. Will McCaddon planned out the launching incline planes and came during his free's. Ryan Libby made the mouse trap and the water bottle filled with bird seed. Austin Koehler made the weight in which the bottle lifted it to hit the lever.

Group 5 Post 5

A) We were successful in our testing, I think it is because of the hard work we put in at 6:30am to 8:45 on the testing day. The day before we had it down, but that was our time to make sure it was perfect.

B) Some changes I would have made would be to make the dominos higher up, it would have allowed for an easier machine below because we could only go so low; the table space ran out.

C) 1-Planning 2-Organization 3-Reliance on members of the group

Group 5 Blog #4

a) We had mutual feelings of a 50-50% chance that our "machine" would work. We were a little behind time so we had to rush to finish. We eventually got it working pretty consistently leading us to believe it would work. Luckily, when it was our testing time it did.

b) On Wednesday, Ryan Libby contributed by marking the heights of the ramps for 30cm, 50cm, and 70cm. Will McCaddon contributed by making the perfect pulley system so the water bottle filled with seeds would drop directly into another bucket launching a weight upwards to hit a ramp. Bobby Buell contributed by making sure as the marble went down a funnel into a tube it would be able to hit a domino then he made sure the domino would set off the rest of the dominos leading to the rat trap pulling the water bottle into the bucket. Finally, I (Austin Koehler) contributed to making sure we met all the requirements. I pulled up the rubric and checked to make sure we had all the simple machines needed, energy transformations, etc.

c) Yes we have filled out all requirements. We had everything we needed in our project. We were not missing any simple machines (we had more than needed) and we also had all energy transformations, some happening more than once.

-Austin Koehler, Bobby Buell, Will McCaddon, Ryan Libby

Group 5 Blog #3

a) The changes my group adapted to from our original design was almost our whole thing. When we begun building, our original outline became too complex so we had to compromise. Examples of changes we had to make from the original design was taking our idea of a weight turning a fan on. We could not make it work so we decided to figure out something else to use.

b) Other major problem we ran into was organization, people in our group being in different physics periods, and time management. However, organization fell into people being in different periods. This was stressful because three of us had the same period so we could work together while one of us had to work alone. With the schedules working out like that, it made it hard to explain to the person by themselves what they should do.

c) Besides energy transfers and simple machines, two other physics concepts we had present in our project were velocity and speed. These go hand in hand together. As the golf ball for instance got pushed down a ramp, the speed went up and so did the velocity. Also, when our water bottle hit the light shooting up the weight to hit a ramp, the velocity was high enough to turn on the light.

Group 15 day 5

A) Were you successful in your test? Why or why not?
To be completely honest, our final test of our project was not successful. Before the final test, everything was going perfect and when we presented, and even after, it continued with difficulties we had never faced before. I think part of the problem was that our project was so sensitive. If one think went to fast, it would set off another.

B) What changes would you do after looking back to the project itself, planning process, or the group dynamic? Why?
I wish we would've done more proper planning. We had a pretty good and set plan at first, but we didn't follow it through that well. What I wish we had done was not rush so quickly. We kind of rushed at the end since we started over completely at one point, and I think that really set us off. 

C) What were three key things your group learned in this project? This may include physics/engineering concepts, planning skills, etc. 
first, we all learned that this was a really fun expierence. It was a blast working on this with a group like this, and even though the project didn't work as we wanted, it was still a good time. Secondly, we learned by our mistakes that we should've planned better. Lastly, we discovered the feeling of things actually going completely wrong. 

Blog 5 Group 23

We were successful in our test as a whole. We were successful because we got the marble to achieve the goals which were asked in the project, some better than others but it still worked out. There was a part during the testing when we had to tilt something over ourself because the weight of the marble was not enough to apply the force needed, which deducted points but not many. Another reason our project was successful because the golf was shot at the distance given to us which was the overall task of the project. If my group had to change anything, we would not have waited til the last day to really get down to business and work hard on this project. This is because we all had busy schedueles and struggled to meet at similar times. Also my group didn't go in and work on the weekend which hurt us in the long run because there was a lot of time available there that we didn't take advantage of. Also, the way we sketched the project before hand was not taken as serious as it should have leaving us confused at times during the actual construction of the project. Three key thing our group took from this were 1. Working as a team will get you farther than working by yourself. When you put four minds together compared to one, it makes a huge difference which is what my group noticed early on in this project. Another thing we noticed was that planning ahead instead of just winging it plays a pivotal role. My group at first walked into the lab thinking we already knew how to do everything but were completely wrong and realized this which is why we set a goal everyday on how far to get in the project. Lastly, our group realized how much physics can be used in the real world. This project could have been done without the use of physics but all of the material we learned this year through out the course allowed us to expand our minds and use all of the methods helping us magnanimously in the project.

Highlights follow each problem and the ways we could have potentially mitigated it, through A & B.

Question A)
Our test [I'm assuming this refers to the one watched for grading] did not run from start to finish. It stopped within the first piece, in that the marble missed the funnel. I believe this happened because we did not have the marble we used for testing the device, which was stolen, because the difference in the marble's weight influenced its trajectory; furthermore, the marble was relatively unpredictable to begin with. In the same portion, when the marble did go through the funnel, it didn't set off the mouse trap. When tested, it functioned with the original marble, but I believe that because we didn't have Drew Ingram there before the test, who was very instrumental in creating that device, and who knew how to set the mouse trap up to make it work, we set the trap too heavily and therefore impaired the mechanism from actually releasing on the weight of the falling marble alone. Last to fail was the pin in the wedge that was supposed to release the marble. The mechanism was meant to function in that when the suction from the bottle released, it would weight the tin can, tension the pulleys, and then pull out the pin. In stead, the pin simply fell out when the large mousetrap shook the board. I believe that the pin was not far enough into the wood to create the necessary friction to resist the change created by the shaking of the mousetrap's transferred torque to the peg-board.

Question B)
Overall, I had a tremendous amount of fun with this project.
I honestly believe that we planned well, but failed to foresee some of the challenges that our ideas presented, and some of the discrepancies we encountered while putting them together in a linear set.
In reference to building, I would have tried to make sure that we stayed on track with construction between days 3 and 5. I think we became so focused on attempting to perfect the first few mechanisms that we neglected to continue to add new ones...
I believe that both of these issues could have been solved by creating a better design, and a figurative time allotment and work schedule for each component.

As a group of disparate personalities, we faced most of our challenges in communication. I experienced multiple scenarios in which changes were made that were not discussed by the group altogether, including by myself. I realize now that if we had more openly discussed ideas, we would have been more efficient. About each of my group members:
Nick Regan's extensive knowledge of tools and experience with mechanics was encouraging and helpful, and Nick communicated honestly and bluntly, which I appreciated. He was also consistent.
Consistency goes for all of the guys. They each contributed in their own ways.
Drew Ingram's sense of humor brightened times when the project seemed unmanageable, and he always held himself and other group members accountable for his each other's own fallacies, respectively.
Michael Bowen was an excellent contributor, and unrelentingly displayed optimism, willingness to work, and an overall 'can-do' attitude, which was encouraging and productive. Bowen is also a good leader, and often attempted to turn the group's attention to managing time well.
I also noticed quite a bit of bickering between Nick and Drew, and, in rare cases only, Michael, and also noted Nick and Drew employing name-calling to make themselves heard. While I don't internalize any of that kind of banter, I know that even when it's not intended aggressively, it can be disparaging to other group members, and is in no way constructive to the actual project.
I frequently felt like a referee between Nick, Drew and, only on seldom occasion, Michael Bowen.
I could have benefitted by using a less assertive tone, and being less demanding of my fellow group members. I often communicated while doing the actual work in ways that, although not outrightly aggressive, were delivered in a condescending tone.

As for the for the marble and the funnel, I would have cut the hose to make the jump longer, then used a metal marble that would be not only more predictable in hitting the funnel, but also would solve the problem of tensioning the mousetrap, because the heavier marble would have been more likely to have depressed the cheese-holder when it was set tightly.
Additionally, I noticed that the funnel moved some on the impact of the marble. With a metal marble, this issue would have worsened. I would have put a zip-tie around the bottom area of the funnel, and through the back holes of the peg-board on both sides, and then tightened it enough from the back side to secure the base of the funnel and prevent its rotation.
As for the pin and the wedge, I don't recall that happening even a single time during testing, therefore I don't believe I would have been able to mitigate it without knowing... Although, I could have simply pushed it into the hole further, which I believe I did during testing with great success.

Question C)
We learned most from each other as friends and peers, about communication, and how to organize projects and keep people accountable for their own mistakes and share of the work. I believe I covered ways that we learned about planning, building and group dynamics in question B.

Group 4 Post #

A. We were partially successful. There was one part that the marble didn't go down for the first time in all of our previous tests, and then there was some duct tape the marble got caught on, which was a piece of trash that was left on the marble track, and then the golf ball did not get released to be launched because the paper clip did not get pulled hard enough to release it.

B. We would have changed the way the golf ball got released.  Our way currently was unreliable and had too many variables, whereas we could have done it on a way that has less variables and would have shot every time.

C. Three things we learned were:
1. We need to plan more, instead of coming up with an idea and start throwing that piece into the Rube Goldberg, instead we needed to have a full, complete plan before we start throwing things together.
2. We learned that every time we set up the Rube Goldberg, everything needed to be set exactly how it was before and we need to check everything is ready to go before we release the marble.
3. We should have split things up more rather than all work on one small part of a piece. As in we should have all been working on different parts sometimes and then worked together to put them together more.

1. What simple machines do you plan to incooperate and how do you plan to use them?
- We are using inclined planes, pulleys, and a wedge.  In the beginning we used several inclined planes to get the marble down to the floor so that it would hit the mouse trap. Once the marble hit the mouse trap then it would snap and pull a string that was attached to a note card acting as a wedge between two plastic tubes and that released bbs and those were guided into an empty Gatorade bottle and that was attatched to the pulley.

2. What energy transfers do you plan to incorperate and how will they be demnstrated in your project?
- We have GPE going to KE, EPE going to KE, we had KE going to no energy at a sudden stop and we had potential energy going to GPE then KE. Finally, we had electric energy in the light bulb that went off.


3. Finally, how has each group member specifically contributed to the project since the start?
- Alex and I drew out the ideas for the sketches and we finally put those together and we had to modify while we were building. Nick did a lot while actually building and he took charge and tried things out. He is a very good hands on thinker. Sebastian was also up there with Alex with coming up when things went down the drain. I was a helping hand while building because I could some stuff and just listened to what the others said. I also bought some supplies for the launcher, Unfortunately, all of us except Nick had class during the testing.

a) We were partially successful in our task. We managed to get the project to run and the ball to launch and in our test trial the ball hit the target. However when we ran during the actual graded run, we needed the tap the machine twice to get the project to run smoothly and the ball just nearly missed the target. Overall I thought it was a success.

b) Looking back at the process I hunk we should have started with the ramp and electrical components first. These were the two hardest parts of the process and it would have been nice to knock these two things out early. We also could have drew a more detailed outline and followed it better so that we wouldn't have to think about what we should do next and waste some of our time.

c) Some key things we learned while do this project was the importance of group work and listening and trying others ideas. Personally at some points in the process some of my group members would suggest a specific idea and I would think there was no way it could work. I kind of ignore the idea and then they would go on and work on the piece they wished to add. It turns out that the piece they worked on was actually really cool and a great addition to the project. Learning to accept help from others was a crucial part in completing this project.

Blog #5 Group 26

A) Were you successful in your test? Why or why not?

We were partially successful in our tests because it tools us multiple attempts to get it to work properly. 

B) What changes would you do after looking back to the project itself, planning process, or the group dynamic? Why?

Looking back at our project we had many ideas for changes that we would do. For example, we could have used a different idea when it came to the electrical circuit and the catapult because they didn't work properly when we used them in our tests.

C) What were three key things your group learned in this project? 

1. That we had to cooperate in order to get the most work done.

2. How to use an electrical drill effectively. 

3. How to connect inclined planes to make a path for a marble to slide down. 

Group #30 - Post#3

A) What changes did you have to do to your original design and why?

We had to find ways to incorporate all of our simple machines and still get as close to a minute as we can. We added funnels, rails and tubes to meet all requirements.

 B) What other challenges have you faced up to this point?

We have faced the challenges of figuring out what we can do to have all of the machines and thing work every time and sometimes having to come up with thing on the spot if our original design didn't work. For example we had to add a bumper to one of our rails so the marble wouldn't fall off.


 C) Outside of simple machines and energy transfers, discuss two other physics concepts in detail that are demostrated in your project.

Torque is shown when the marble fall on a lever pushing up another side to then move a golf ball. We created more torque for a smaller object to move a bigger one. Also there is electric circuits being used by touching clips to a conducted in order to complete a series circuit

Group #30 - Post #5

Blog 5 Questions: A) Were you successful in your test? Why or why not? Yes, our test was extremely successful as it ran flawlessley without the need of help or a restart. The ball hit the target perfectly at launch and i felt that we explained our requirements well. B) What changes would you do after looking back to the project itself, planning process, or the group dynamic? Why? Looking back, I think better planning is in order to make a better method for working through issues. Most of our parts were made on the fly and while they worked, it would have saved time to have a plan. Also I think the tools were scarce until groups began to bring their own. Without the use of home tools, the project would not have been possible in the time frame because of the amount of work that can be done with the tools. I think the bringing of tools from home was a good idea and necessary. C) What were three key things your group learned in this project? This may include physics/engineering concepts, planning skills, etc. We learned that a plan is the best method for success. Also that more minds can create solutions that are more efficient and better all around. Finally, in regards to construction and physics in the real world, we learned that physics is not always consistent in this type of setting and security and stability is everything.

Dylan Pflum Friday blog post

A) Were you successful in your test? Why or why not?
We were for the most part successful in our actual testing. Our project was able to run all of the way through with only one tap. However, our project was not successful in terms of having all of the components necessary. For exMple, we did not have 5 different energy transfers or have a working electrical circut.
B) What changes would you do after looking back to the project itself, planning process, or the group dynamic? Why?
I would have made sure that all group members would have been able to attend afterschool and before school building times. I learned that this project is very hard to build when you don't have all your group members present. This would help becasue it would speed up the building time alone allow more time to add the necessary components.
C) What were three key things your group learned in this project? This may include physics/engineering concepts, planning skills, etc. 
One key thing I learned is how you need to be dedicated to work on a project like this. Another thing I learned is that you have to be willing to out in 3+ hours a day inorder to complete these big school projects. The final thing I learend is how to use pulleys and counter weights better.

1. We were sort of successful, we didn't get he distance right, but the ball was able to launch with only one "touch" of the marble. Distance was really the only issue with our test.
2. I would definitely gather supplies earlier and create a plan with the group rather than do it by myself. I also wouldn't waste as much time and use time after school to work on it and problem solve. It was hard to get a perfect design because this project is so unpredictable. I would also make sure to have all of the requirements before we built it. 
3. We learned that we have to check to see which points we should go for before we start. Take the easy points first and go for the harder ones as you go, rather than just try to complete the task. We also learned that it's better to have more space to work with from the start. We began to run out of room really quickly and we had trouble from there on out. Finally we learned not to procrastinate so much. We didn't get a lot of work done during class, and didn't take advantage of using free periods and time after and before school. This really hurt us in the long run as we struggled to finish and had a very sparse, simple project.

This is our group's video of our Rube Goldberg Project working completely without any issues.

Blog #5 Group 16

A) We were not successful when we tested for the teachers due to the marble not being able to remain on the incline planes, it fell off multiple times which was odd for the group to see because we had a couple complete runs the day before testing.

B) If we could change something, I think we would try to change the time that we had together as a group to extending the deadline so that we could have had more time to check or project and make sure everything was in tip top shape.

C) As a group, we learned that it is always easier to thoroughly plan out your project before hand, that if we get 1 complete test this doesn't mean that it is always going to work, and that is easier to communicate and work as a group if all participants are there in the same periods.

A) We had to make several changes to our outline. We had to get rid of the original pulley we planned because it just did not flow properly, we also never ended up following through with including a yoyo, we subbed the yoyo with the golf ball in some ways, and we added a new aspect of the falling marble, wood, and bucket idea also.

B) At this point in the process, we are having a tough time figuring out how to use an electrical component. We are not sure how to incorporate this into the design and have it work. Also, we are struggling to make the time limit. It is harder to waste time than we thought.

C) One topic we discussed about in physics was the topic of forces. Gravity applies a force on the marble at the top of the ramp, causing it to go down the course. There was an applied force on the golf ball. The marble applied a force on the ball, causing it to go down the tube. One more topic we discussed in physics class is the idea of projectiles. We launched the gold ball 50cm out of the tube. We calculates the correct angle for it by using kinematics. We were able to get very close to landing at exactly 50cm.

A) Our group plans on using a lever, pulley, and incline plane. We will use the lever to drop a marble onto the incline plane, the pulley to raise a bucket which sets another marble in motion, and the incline plane allows the ball to move towards the incline plane.

B) We plan on incorporating PE to KE, KE to KE, KE to PEg, PEg to PEg, and PEg to KE. PE to KE- stalled marble starts accelerating down an incline plane, KE to KE- moving pill bottle collides with a PVC ramp causing another marble to roll down into a funnel, KE to PEg- marble continues to roll down incline plane and lands in a little bucket which drops to the floor and triggers the pulley, PEg to PE- bucket falling to floor causes the still pill bottle on the other side of the pulley to move upwards towards the PVC ramp, and PEg to KE- falling golfball transitions into a golf ball moving down our ramp.

C) John Michael and I have made the incline planes and screwed them into the board, and Cole and Oliver have positioned the funnels and attached them to the end of the incline plane.

Day 8 - Group 9

A) We were not able to complete the objective of scoring the ball on the target. Two or three parts of the machine at certain parts throughout the process either failed or were not completely accurate, and out targeting mechanism only worked a percentage of the time anyway. Other than that, the rest of our project worked well outside of testing (of course).
B) Looking back, I’d say we should have used our first few days more effectively. Towards the end, we were able to get a lot done faster because we spent all of our free time working on parts, along with working on many of the parts at home. Earlier on, we hadn’t done that enough as we probably could have. The planning process took up the first 2-3 days and continued to adapt throughout. Overall, we had a pretty solid planning process for the amount of time we were dealing with. As for our group dynamic, we probably could have involved all the member’s inputs on the initial design process in order to see a broader amount of ingenuity and ideas about how to solve the problem.
C) We certainly learned that we needed better organization skill. Not everyone was building as efficiently on the first few days that were vital due to the short amount of time we had. I think as a group, another thing we learned was that when staring in the face of inevitable failure, the best thing to do is to cut your losses. Lastly, we of course learned how to use simple machines in order to gain mechanical advantages and use simple devices to achieve complicated tasks.

1. No. Our test was unsuccessful because or catapult launched a golf ball that missed the target by 2 inches.
2. I would change it so that our light bulb was as the end of the project or to the point when it turns on right behind the catapult launches the golf ball. I would also test our catapult more so that we would've know if it worked every time without any mistakes.
3. It taught me that we should plan when to work on the project the day before, teamwork helps the most if all participants can work quickly and efficiently together, and that working on something that is later on in the project during the work periods even though you don't have the parts for the current object you are building.

A. We anticipate being successful on our testing because we have taken a video of the project operating properly already and have met most of the requirements.
B. Liam and Bennett designed a ramp for the launching of the golf ball and added a light switch connected to a fan that releases the golf ball and launches it off of the ramp. Dante, Michael, and Colton designed the tubing and tracks that run along the boards and added funnels that lead to the light switch.
C. We have three simple machines, a pulley, lever, and inclined plane, and a several energy transformations. These include GPE to KE, KE to KE, KE to GPE, GPE to KE, chemical to electrical, and electrical to kinetic.

Blog #3 Group 14

A. We redesigned the railing on the board in order to make them take up more time. Also, we remade the ramp for the golf ball and added an extra wooden component that will connect to the boards. These changes were mostly made to avoid cluttering the boards and to increase the duration of the project.
B. We have had difficulty wiring the fan and light bulb to our battery and have had to buy new supplies in order to get it to work. Also, we are still considering how to make the ramp for the golf ball adjustable.
C. First, we have an example of an elastic collision right before the pulley system. We have a marble go down the tubing on the board and eventually reach a golf ball that it collides with and sends rolling into a cup. However, the marble also continues to roll in the same direction as the golf ball because they are on an inclined plane. Next, we have an example of a circuit right before the ramp for the golf ball. We have connected a light switch to a 6 volt battery and a fan to the light switch. When the switch is off, the circuit is incomplete and the fan does not move, but the circuit is completed when a marble falls and flips it on.

Blog #2 Group 14

A. We plan on using a pulley and a lever. We plan to attach a cup to a piece of wood with string and hong it over a pulley. A ball will roll into the cup, push the cup down, raise the piece of wood, and the wood will hit a lever. This lever will have a marble sitting on it that will be released after it is activated.
B. We plan on including gravitational potential energy to kinetic energy, kinetic energy to gravitational energy, kinetic energy to electrical energy, and electrical energy to kinetic energy. The first energy transformation will be accomplished by having marbles start at a high position and gain speed as they go down tracks. Next, we can achieve KE to GPE by having a rolling marble enter the pulley system and release another marble that is at the top of another board. Then we can let the second marble go down a set of tracks that lead to a funnel pointed at a light switch. Finally, the light switch will turn on a fan and light bulb.
C. Liam and Bennett have been designing a ramp for the launching of the golf ball and have been working on adding an electrical component. Dante, Michael, and Colton have been working on making the track for the marble and placing them on the boards.

a.) We were partially successful because the gold ball launched and hit the target, however the electric component did not work successfully.
b.) We would make the project longer by adding more incline planes and we should have slowed down the pully process. Also we would have changed the group dynamic because not everyone was there at the same time to work on it together.
c.) 1. Picking our group members more adequately
     2. The machine process took a lot less time than we thought it would do to a lack of better planning
     3. We got the most done when we were all there together working on it compared to 1 or 2 people working on it

 No because we didn't have the project working 100 percent before out testing time.
B) What changes would you do after looking back to the project itself, planning process, or the group dynamic? Why?
Work after school
C) What were three key things your group learned in this project? This may include physics/engineering concepts, planning skills, etc.
That you need a lot of air power just to move a marble, that different sizes of marbles only work for certain tracks, and the slightest problem in the track messes up the whole run-through.

B.)The changes I would make to the project is I would remove the water wheel and water bottle contraptions. This contraption was very difficult to operate and required several class periods of works and still didn't function correctly most of the time. Instead I would change the the water wheel to a pully system with cup attached. In our planning process I would change our group drew a rough sketch to begin the project but did not fully draw a complete plan until half way through which caused great confusion among the group members. 

C.)During this project my group learned that we should have made an exact drawing to being with, we should have spent less time building our base, and we learned we should have spent more time before school and after school.

our test was successful in that we were able to run all the way through without a mess up on the first try. We also hit the target on the first try. If I could change anything it would be to make our ramps more flat to eat up more time and also to add a light bulb. If I learned anything from this project it's that hard work can actually end up as something pretty cool and that duct tape fixes everything.

1. Our group was not successful in our test. I believe this to be because we did not mark the length at which the pulley needed to be at.We also should have added a wall to some of our inclined planes so that the marble wouldn't slide off. 

2. Looking back on this project, the one thing I would change is the amount of time we spent during the first week on our first pulley.We had a design but we did not start sticking to it until Sunday. 

3. Our group learned that a good design that everyone agrees on is important to progress, because if not then different people try to do their own design. Everyone trying to build their own design gets you no where and wastes time.We also learned that when building things you shouldn't use weak materials as a way to get it done quicker rather than building a sturdy structure that will hold better.This project also helped teach us more about electrical circuits through us burning out multiple lights due to short circuits. In the end our light was wired correctly and worked well. Overall this project taught us that cooperation is key when working with others and a pre drawn design makes the process of building easier.

We ran into many issue with our original design because it did not have a launching system or an electrical component. Also our original design would not have made it within the required time limit. The marble was travel at a rapid rate because there were no forces stopping it. Another challenge we faced was the challenge of adding on more boards to allow for more room for the ball to travel. In the original plan we planned on using two boards to do the entire reaction. However, the two boards only allowed us to fit so many simple machines and devices. To help make the reaction longer and to to add more simple machines and devices we needed to add another two boards. Another issue we kept having was the issue of stability for the entire reaction. Finding a method to connect the electrical components was also very difficult. We had a domino effect that allowed energy to transfer from one domino to another than once the dominion reached the end of the wooden beam it would fall into a cup connected to a pulley. Another is when the marble hit the car so that the car would hit the mouse trap causing the catapult to trigger.

A. We were successful in our test. Our first test went really well, and our ball hit the target at 50cm, there was just a small hiccup on the second half of the track, but it was fixed immediately. Then on the second test, Mr. Von just wanted to make sure the second half of the track worked, so we showed him that the whole machine worked.
B. Honestly, there is very little I would change about our project. I thought it turned out extremely well, it looked good, and our whole group worked well on it and had fun doing it. The one thing I might have changed was the planning stage, we were too ambitious when planning and got caught up trying to do the impossible.
C. Three things we learned are bring your own tools so you don't have to share, pick a group that you know will work hard and work well together, and don't get too stressed out by this project, the teachers are super nice and will help you along the way.

A. Yes and no. We were able to hit the target but our machine did not work all the way though because a stray ball hit our launcher as well as a few other random issues thst caused the machine to fail.

B. We probably should have planned better in the beggining in order to have more structure instead of doing it on the fly because we probably would have not been as strained for time.

C. We learned about the difficulty of completing the project under the time constraints and how challenging it is to make the project last long enough.

A) Were you successful in your test? Why or why not?
-Yes we were successful in our test as the ball landed on our mark and turned the electrical component on. The first try was not successful because the target and the ramp releasing the golf ball was not lined up correctly. After adjusting the target, the ball hit at 30 cm.
B) What changes would you do after looking back to the project itself, planning process, or the group dynamic? Why?
- One change would be to select group members in the same period as you. It makes the building process easier but our group was still successful. Also, I would change the planning process to begin a little earlier task that we can start right away. The building takes time and a lot of troubleshooting.
C) What were three key things your group learned in this project? This may include physics/engineering concepts, planning skills, etc. 
-We learned that organization and communication are very important in group projects. Also, we learned and became better with electricity and building circuits. Finally, we learned about other energy transfers that were not covered as in depth in the year.

Blog Post #2

I do anticipate being successful in testing, because each individual component has worked on their own. We had some trouble holding everything together, however we resolved most of those problems.
Each group member has contributed in their own ways since Wednesday, with some of us coming in before or after school, as well as working on it together every class period.  We have all brought inseparate building materials and tools as well to use.
We have fulfilled all of the simple machine requirements, but we still need to add 1 or 2 more energy transfers in order to receive full credit for them.  Most of this has been due to time constraint, but adding the machines was pretty simple.

Blog 5 Questions:
A) Were you successful in your test? Why or why not?
We have not tested out machine fully but we are going to do this tomorrow morning and we intend for it to work. The reason we have not finished a test run is that we have had many complications with some of our ideas and machines.

B) What changes would you do after looking back to the project itself, planning process, or the group dynamic? Why?
One thing I would change would be how we built the machine. I thing we should have actually had a plan before we started building the machine. This would have alleviated many stressors that our group faced.


C) What were three key things your group learned in this project? This may include physics/engineering concepts, planning skills, etc.
One key thing out group learned was teamwork and that one person can not complete the project alone, that they need the help and support of the other group members in order to complete the project. Another key things we learned is that we have to have an actual plan before building and to create the framework before actually stating to add the track and other pieces to the machine. The final thing we learned from this project was that it is very hard to predict what something is going to do, the ball or object does not always do what you want it to do so we must account for these times and build the project accordingly.

Blog 4: Channing Jake Nick Alex (group 8)

Blog 4 Questions:

A) Do you anticipate being successful in your testing? Why or Why not?

Yes, we do anticipate being successful in our testing because we have put a lot of hard work into this project. Although at the moment we are not done, we are are very closely narrowing in on our finished project. So far our tests have proved to be very accurate, as we have tested the project multiple times and don't expect to encounter any errors during testing.

B) How has each group member specifically contributed since Wednesday?

Jake attached the tubing around the pvc pipe and timed it to make sure we could get as close to a minute as possible, Channing designed and built the new water releasing mechanism, and Nick built the water wheel. Along with this each group member has been helping to fix problems associated with beginning stages of the project.

C) Have you filled out all the requirements of the project? Particularly the simple machines and energy transfers? Why or Why not?

Yes, our group has done a great job following the rubric and incorporating all simple machines into our project. As far as energy transfers our groups has done an outstanding job of finding innovative ways to use the materials provided to us to perform energy transfers effectively and be able to use them to our advantage. My personal favorite energy transfer in our project is our use of the mouse trap jumping from elastic potential to kinetic energy, allowing us to move a very heavy weight and release a pool ball. 

Blog 2 David,Chris,Thomas,Pierre

A) We plan to use an inclined plane, lever, screw, and pulleys. Our inclined plane is for the marble to travel down our board.The levers are to elevate and move objects.We used screws to screw in parts to our support board.And our pulleys to move objects up and down with string.
B) We plan to incorporate kinetic to kinetic, Gravity to kinetic, kinetic to gravity, electric potential to light, and elastic to kinetic. In order to go from electric potential to light we are completing a circuit that turns on a lightbulb. For kinetic to kinetic we have the ball rolling down PVC pipes. For Gravity to kinetic we have a spot where a ball is resting on a PVC pip and is tipped over to use its gravity potential to turn into kinetic. We also have kinetic to gravity when the ball falls out of the PVC pipe hitting the mouse trap. And our last energy transfer is from elastic to kinetic in which we tied a string to a mouse trap which goes off and ends up using a pulley to knock off a marble from a PVC pipe.
C) Specifically, Chris has brought in supplies, cut PVC, glue objects on the board, and blogged our project. David has bought a lot of supplies we needed such as PVC, light bulbs, fan, battery emulator, wire and jimmy johns.Thomas perfected the blue print, brought in batteries, the hot glue gun, and has help cut and build up our board. Pierre has helped glue on pieces, brought in bells, glue, ramps, and tape, as well as help perfect the blue print.

Blog 3: Channing Jake Nick Alex (group 8)

A) What changes did you have to do to your original design and why?

We haven't had any major design changes, except for the mechanism to release water. Our original plan was to have a small board which the lid of the water bottle pushes against until the board is knocked out of the way by the cue ball, releasing the water. This did not work because the board was very hard to move, it usually would stay attached to the water bottle, and it did not create enough force to push against the water, resulting in the water spilling onto the project. We switched out the water bottle, instead we have one with blue removable cap which we tied a string very tight around. On the other end of the string is a metal hanger which will provide enough force to yank the cap off, thus releasing the water. This piece of metal will be pushed off of the inclined plane by a wedge, which is hit by the cue ball.

B) What other challenges have you faced up to this point?

The construction of the water wheel has proved to be very challenging. The water wheel has to be very light in order for the water to be able to turn it, and materials like these are very hard to come by. This construction has delayed the building of our project and will likely be one of the more difficult issues faced in this project.

C) Outside of simple machines and energy transfers, discuss two other physics concepts in detail that are demonstrated in your project.

One concept demonstrated in our project is when the metal hanger is knocked off of the plane and suspends itself in the air to open the water bottle. This uses the physics concept of Newton's Second Law of Motion, or F=ma because due to the weight of the hanger and gravity, the force has to be a certain value. It cannot be too much, or else the cap will break or the string will slide off, however, if the force is not enough, the cap will not open up and the water will not flow out. In order to find the right weight we had to use this physics concept.

Another physics concept we use a lot in the project is Newton's First Law of Motion. One example of this occurs when we have the cue ball resting at the top of the inclined plane. It rests on the inclined plane due to the force pushing into the ball by the bucket, causing the ball to stay at rest. It is not until the bucket drops down that the cue ball moves, because the ball was acted upon by an outside force.

Blog 2: Channing Jake Nick Alex(group 8)

A) Which simple machines do you plan to incorporate and how do you plan to use them?

We plan to use five simple machines in our project. First, the pulley will hold the bucket up until released by the mouse trap. Next a cue ball will roll down our inclined plane. This cue ball will hit a board out from the water bottle and the water will spill down a screw. The water will then cause a water wheel to spin, which is a wheel and axle. Lastly the lever will activate the slingshot, causing the golf ball to be launched.

B) What energy transfers do you plan to incorporate and how will they be demonstrated in your project?

The main energy transfer we will be using is when gravitational energy is converted into kinetic energy. Some examples include the marble rolling down the tube and onto the mousetrap, the cue ball rolling down the inclined plane, the water flowing down the tube onto the water wheel, and the second cue ball rolling down the inclined plane.

C) Finally, how has each group member specifically contributed to the project since the start?

Each member has been working together very well in finalizing the main structure for which we will build the actual project on. Specifically, Jake has brought a drill from home and worked on securing the wooden blocks to the peg boards, Nick has been cutting and adjusting the wood so that it will fit and increase stability on the structure, and Channing has been tieing the adjustable knots that add support to the walls and floor boards.

Blog 1: Channing Jake Nick Alex (group 8)

A) Who is in your group and why did you guys decide to be a group together?

Our group consists of Channing Washlesky, Jake Wilemon, Nick Colaluca, and Alex Reilly. We decided to be in a group together, because we are all friends and three of us had previously done the toothpick bridge project together.

B) What is your initial plan to fulfill the objective of launching a ball a given distance?

We are planning on using a slingshot to launch the ball a given distance. We decided on a slingshot because it can be easily adjusted and is very reliable.

C) What challenges do you anticipate facing?

Having everything work at the same moment. This is anticipated because from watching previous students do the project, it was apparent that during the testing sometimes certain steps would work, but then they wouldn't work in the next test.

Blog 4 David, Chris, Pierre, Thomas

A) As of right now we do anticipate being successful on this project. We have run multiple tests in order to figure out all of the little things in our project that mess up. We have also spent a lot of time making backboards for the marbles so they do not miss a mouse trap or stop/fall out of an incline.
B) Thomas Chris and I worked on the blueprint together while Pierre has helped a lot with the building process. We have all been working thoroughly on cutting pipes, adding backboards, and glueing and ziptieing things. We have also most of the time come during our free periods and after school to work on the project. It has been a great group effort so far and I think with the hard work we have put in will result in a successful project.
C) We have met all of of the requirements for the project because we spent a lot of time on the blueprint making sure we had all of the requirements. The only thing that we have not met is the time requirement of at least 45. We did not have enough time wasters and are about five seconds short of that mark.

Blog 3 David, Chris, Pierre, Thomas

A) We aren't using the dinosaur as we originally planned to, to show the audience when we are launching the golf ball.We are using a funnel to start off the project. We are using two marbles in our project.
B) Something we've faced is when the marbles are going down the ramps and through the PVC, when coming to the end of the ramp and transferring onto the next, sometimes they fall too far off track and miss the next ramp to go down. C) One concept is circuits, we were rolling a tin foil ball onto two wires to complete a circuit and light a light bulb.Another thing is the force of the fan blowing another object being the tin foil ball onto the wires to light up the light bulb.

Day 5 Group 36

Blog 5 Questions:

A) Were you successful in your test? Why or why not?

Some of our earlier tests did not work; however, with some minor adjustments we were able to complete many successful tests.

B) What changes would you do after looking back to the project itself, planning process, or the group dynamic? Why?

Looking back at the project, I would  like to do a more elaborate design in order to get the marble to reach the curcuit. I would like to do this because I feel our design is basic and lacks creatively but still accomplishes the job. 

C) What were three key things your group learned in this project? This may include physics/engineering concepts, planning skills, etc. 

1. Plans are changed from orginal design multiple times

2. Always make sure the entire group is on the same page

3. Do not try and make something too complex 

Group 20: Blog #2

A: We are going to use a screw- by having a ball fall down and travel through a funnel attached to a tube that wraps around an upright 2x4. We will also use multiple pulleys, where a marble will push a block of wood into one cup and cause it to fall while the other cup rises and knocks the second marble off a ledge to fall down a tunnel. Lastly, we will use various inclined planes for the marble to travel down to the next checkpoint of the project.

B: Energy transfers we plan to incorporate are potential energy of gravity to kinetic energy: when the marble is resting on an object and gets hit by a lever. We will also have kinetic energy to potential energy: when a moving marble hits an object after traveling down an inclined plane and then stops. We will have chemical energy transfer into light energy when the circuit is completed, which is caused when the ball hits a clamp and completes the circuit, allowing there to be light. We will also have elastic potential energy to kinetic energy: when the rat trap triggers, it pulls a string that is attached to a pole, which causes the pole to fall down.

C: We have worked together pretty well. Chris has done a lot in providing ideas like how to get the circuit to work and how to launch the golf ball and providing a drill to help speed up the building process of the project. Ethan has helped put the system together also by helping place tracks where they need to be. We have all worked on the project during our free periods and before and after school. Justin and Eddy have helped with the outline of the design and have provided assistance with a hot glue gun some other tools(like a second drill and scissors) that have helped putting the project together more efficient.

Blog Post 4- Group 41

A) Yes, because the first machine, the plinko,  is the most difficult step to go through in the process and we have gotten it down to where we feel confident enough about the other steps because they all rely on the plinko.

B)  Dao finished the water mechanism, creating a new funnel system that take more time, and the boat part. Kenneth finished the bottom mousetrap launcher, for the golf ball. Garrett created a mechanism that splits two marbles one going to the plinko and the other setting off the water mechanism. I built a support structure for the split wedge thing and help with making the of the wedge thing that is connected with the mouse trap launcher.

C)  Yes, we have made a pulley, incline plane, wedge, another incline plane and wedge, for the energy transfers it goes from GPE, to KE, to a different KE so we have finished off the energy transfer requirements and simple machines ones as well.

A.) The changes that we had to do to our original design are we had to construct a screw at the top of our project to fit the time requirement. We added a tube at the beginning to add time to the project. Lastly we added a mouse trap to help secure our bucket with our pellets.
B.) The challenges we have faced are securing the pellets in the bucket, so the bucket falls and releases the pellets on impact. Also, we needed the pulley to drop from a higher height, so when it hits the tambourine it hits the appropriate height,.
C.) We had to deal with both static and kinetic friction when the marble goes down the inclined plane. We had to control it do the marble stopped and went down the rest of the track. Also, Gravitational potential energy when the golf ball falls and hits the trambourine. We had to increase the height so that the ball went farther.

Blog Post 3: Alex Frey

A. One major change we have made to our original design is the fact that we are no longer building the entire project on one side of the board but we are now building on both sides, back and front. We made this decision because by utilizing both sides, it 1. Displays intricacy and thought and 2. It allows for more space to build. B. One challenge we have faced up to this point is actually building on the back side of the board without disrupting what is on the front side and vice versa. Sometimes, incline planes and the zip ties that hold them get in the way of other simple machines and devices on the opposite side, resulting in a bit of reconstruction that takes up precious time. C. Besides simple machines and energy transfers, two other concepts related to physics would be that of projectiles and that of collisions. Concerning projectiles, the whole aim of the project is to launch a golf ball and have it land on a plate some centimeters away, well by calculating the angle at which it is launched, the weight of the ball, and how fast it is launched, we can estimate the approximate landing spot of the ball. The concept of collisions comes into play when in our project two objects hit each other, resulting in one object moving forward and another staying still. For this to work, things like mass and velocity must be accounted for. Group 32: Alex Frey Nick Hartley Gordon Webb Sebastian Tran

Blog post # 3 - Group # 27

1.For the most part our design stayed the same but we had to do a lot of fine tuning in order to make our project flow together well and waste time.
2.It has also been a challenge to put different things on our board with out totally destroying them. Another challenge was to put things on our board at the right angle.
3. Another physics concept encorporated into our machine is electronics. We are going to use a pressure plate to complete our circuit and allow the flow of electrones to reach the positive charges that they are attracted to.

A) Do you anticipate being successful in your testing? Why or Why not?
-Yes because we have tested it many times with success. The only challenge is setting it to the specific distance asked for. 

B) How has each group member specifically contributed since Wednesday?
-We have slowly built the project in stages and each person has contributed with each stage. Also, we all have brought different and necessary resources that were needed in the building process. 

C) Have you filled out all the requirements of the project? Particularly the simple machines and energy transfers? Why or Why not? 
-We have filled everything out except the wiring for the light that needs to turn on when the golf ball lands.

Day 4 - Group 4

A) Do you anticipate being successful in your testing? Why or Why not?
- Yes, of course we do, but I wouldn't be surprised if it does not because there are a lot of variables in the rig that if one thing goes wrong, then everything else stops working.

B) How has each group member specifically contributed since Wednesday?
-We have all been meeting up in our free periods to help equally. Parker has come up with some ideas such as hitting the light switch with the zip line and had contributed work time with it. Mac came up with the idea of the actual zip line part of it and worked to do that. Luke has been there to help out all the periods and to lend a hand. Lastly, Pete came up with the idea of the pin that gets released from the race car track and designed that aspect of the Rube Goldberg.

C) Have you filled out all the requirements of the project? Particularly the simple machines and energy transfers? Why or Why not?
- Yes we have. We want full points incase the golf ball does miss the target.

Parker Cicerlli, Mac Elliott, Pete Hanrick, Luke Laufenberg

Day 3 - Group 4

A) What changes did you have to do to your original design and why?
-We had to go way off ur original design after the first few steps. It looked good on paper, but once you out wood and metal together and start building, you run into accuracy issues, weight problems, and true functionality problems.

B) What other challenges have you faced up to this point?
- Some challenges we faced was trying to get the marble to hit the mouse trap every single time, and get it accurate enough, another was getting the cork to come out of the glass bottle  via the mouse trap.

C) Outside of simple machines and energy transfers, discuss two other physics concepts in detail that are demostrated in your project.
-One is circuits; we dealt some time with putting together a fan that gets turned on by a switch that gets flipped via a "zip line."
Another is force with collisions when the zip line attached to a duct tape ball hits the golf ball, there is an inelastic collisions because the ball moves with the golf ball for a split second to give it that push.

Group 20: Blog #5

A. Yes we were successful in our test because, we have tested it multiple times and we have made necessary adjustments throughout and these adjustments have helped us in making our project more consistent and has allowed us to fix certain structures into becoming more stable.

B. Plan out the project ahead of time instead of planning it out as we go along. This would decrease the amount of time we had fixing mistakes and would enable us to finish quicker so that we could focus on other priorities for the project.

C. That in order to make ball continue its momentum, you must have multiple ramps and elements that make the ball roll faster. The electrical component must be activated by some object like the dropping of a ball so that it can activate the circuit which would cause a light to turn on. The ball must be launched at different angles in order for it to travel different distances (30cm, 50cm, 70cm).

A) Do you anticipate being successful in your testing? Why or Why not?
Of course. We are working very hard to make everything perfect. We test it constantly everytime we construct a new piece so we will know what works and what doesn't. 

B) How has each group member specifically contributed since Wednesday?
Each group member participates and contributes really well. Joseph and joe made the pully, which took a while to develop. And andrew and I spent all day Monday reconstructing the beginning of the project since we were having difficulties. Everyone has been contributing equally with ideas. Overall, it's been a fun expierence.

C) Have you filled out all the requirements of the project? Particularly the simple machines and energy transfers? Why or Why not? 
In the process. Right now, we have 2. We have where gpe converts into ke. Also, we have a collision that transfers a car into a cup, that raises the pulley.

Blog Post Question 3- Group 41

A) While building the final catapult part we had to alter what causes it to launch, we had to change from a string pulling and launching to, a different mechanism that is actually strong enough to pull it. When making the plinko machine, giving a wood post to stop the marble from falling out. Since we couldn't hold up the fan we wanted at the end of the plinko machine we had to string it up and hot glue it with the end of the ramp with the marble.

B) Making the marble actually go through the entire plinko without it flying out or hitting a screw and missing the fan. Building a funnel system that it good enough to take a lot of time out. Finding a sufficient way to launch the golf ball.

C) Kinematics, finding a good angle to launch the ball to the certain lengths on the ground, in actually predicting how the golf ball can output the amount of force needed to launch it far enough. The water moving through the funnel and tube, shows the water moving through and taking the shape of the container it is in.

Day 4- Group 25

A) Do you anticipate being successful in your testing? Why or Why not?

I anticipate our group to be successful in our testing, but the duration of the project may be an issue due to the fact that the current state of our project is still not in the finishing touches, but rather our group is still in the building phase of the project.

B) How has each group member specifically contributed since Wednesday?

Each group member has made a significant contribution since Wednesday. We have met with one another outside of class, during free periods, and lunch to discuss and create new ideas to add to the project to increase efficiency and accuracy. We all find time throughout the day to work on the project, whether it is individually or as a group, we find a way to make it work and maximize the limited time given to work on the project.

C) Have you filled out all the requirements of the project? Particularly the simple machines and energy transfers? Why or Why not?

We have not filled out all the requirements of the project yet. We have 3 simple machines and are in the process on creating our fourth simple machine. The reason we do not have at least five different simple machines because the incorporation of the simple machines with one another must actually work, rather than just putting different simple machines together and not able to complete the intended task.

So far our project has trouble with consistency, but that why we keep testing and tweaking things. Nick has shown up during free periods and after school to work on the project, mark has done the same. Louie and Richard provide good work during class time because they cannot show up after school due to schedule conflicts. We have a circuit, our simple machine and our energy transfers, I am mostly worried about the launcher and time.

Our design for the pulley changed from having something on the pulley tip the next ramp, to having the pulley simply tip the ramp with the force exerted on the string itself. So far there have been problems with cooperation and some ideas that weren't accepted. For our launcher we are using gravity to supply the force for the launch. Also our launch distance will be determined by the angle of the ramp.

1. I don't expect to be successful in our testing to begin because it will be tough to get the distance right and be able to adjust it. However, I think once we work out the kinks, we will be able to get it. 
2. Charlie has put up an extra wall and fixed the first step of our rube. Nathan, Zach, and I have completed and built a couple of more steps. 
3. We have a couple of energy transformations: kinetic to kinetic and potential to kinetic. Also, we have a lever, a pulley, and am inclined plane but we don't have our electrical components yet because we haven't figured out how to work it. So we have most of the requirement but not all of them.

we plan to use a pulley, a lever and an inclined plane. The pulley is powered by a fan motor that is turned on by the marble hitting a switch. The lever is activated by the pulley pulling on the side of a tube tilting it, sending the next marble into action down an inclined plane. we have electric energy to Kinetic energy, GPE to KE, KE to Electric. Nick has come in after school, and engineered the pulley and tested and tweaked until everything is perfect. Mark wired the fan and set it up to the Pulley along with the switch. Louie set up some of the ramps and always has good ideas. Richard has also helped with the structure as a whole and Is always providing ideas and staying positive.

A. Well we realized that the pulleys took up a lot of room on our first board so we decided that in order to fully create a project which is both pleasing and accomplishes the task while including the requirements we would need to extend it so we added another board, which allowed us more freedom to at simple machines and time wasters.

B. Well when rolling the marble down ramps and up pulleys we realized that there are times when the marble will fall off track so we found a sweet spot to realize the marble from so that it wouldn't fall off. There were also times when the strings on the pulleys would get stuck and that would cause the entire project to malfunction so we made sure that before we tested the project we had to check to make sure every part was in place and ready to go.

C.
In order to meet the requirement of having an electric component in our project we used what we learned about conductors earlier in the semester and created a way to use a marble wrapped in foil in order to let energy travel to a fan, thus turning it on and allowing for our project to continue along its path. Another concept we used relates to the slingshot lab we did in the beginning of the year and we used it in order to help us calculate how we can hit whichever target the judges ask us to hit.

I anticipate that we will be successful at testing because of all the minor adjustments we made to make sure that everything is able to fall into place with minimal amount of error. Occasionally it might fall out of place and fail, but that is when we attempt to find solutions to where it will not make the same mistake and come out with better results to finish the task.

Every member in the group has contributed in their own way. Some would work on how they would involve all the requirements need to make a successful machine, while others would help build. Of course we would all collaborate and see if one's idea is better than the other and at other times we would all jump in and give the assistance need to help build our visual idea.

I feel that we have filled out all the requirements asked for in the rubric because that is the first thing we focused on and how we were going to build it around those ideas. We made sure that we were using ever simple machine right and asked questions if we were not sure.

Blog 4 Questions:

A) Yes because we are constantly testing and making sure everything is working properly. We continually test to assure no mistakes are made before the final test. We have everything calculated specifically, and we are very confident because we test the parts multiple times.

B) Each of us have contributed our own personal ideas onto the project. We have personalized it to where we have made it an equal combination of our ideas. Hunter mostly helped start us off, Michael Lohr, Landon and I have been mostly working on the big part of our project that we have left while Hunter has been working on the electrical circuit completion.

C) Yes, we have we are just improving the parts that we are not too confident about. We are using a mouse trap and a fan to transfer energy. We have planned out all requirements but we still have a couple installments to make and improvements to make.

A. I do anticipate being successful in our testing because through trial and error, we have found the correct marble paths and trajectories the marble must travel in order to successfully complete our Rube Goldberg project/circuit. Tune-ups and minor tweaks will continue to be necessary as our group gets closer to completing our Rube Goldberg project.

B. For the most part, our group has been able to productively work and cooperate together, but some communication issues have started to occur as the final week of our project begins. For instance, Drew had work during the time that we were working on the project Sunday afternoon, so he let us know he wouldn't be able to make it. Also, he asked how he could continue to help and "make-up" for missing the group time Sunday. Drew ended up working on 2 blogs and gathering material to support the group that day. Second, Nick has been very helpful with his time and craftmenship. Nick has been brainstorming on the idea of how we are going to launch the golf ball and taking advantage of his free time to build simple machines or electrical circuits required for the project. Nick has been very helpful with his skill of building and assembling materials for fhr Rube Goldberg project. Third, Pascal has also been very helpful with his craftmenship and resources. Pascal has always looked for an opportunity to use another piece of equipment in our design. He has worked very hard on the suction and pulley system with the glass battle and his materials he has brought in make the project a lot easier and productive. He did forget or denied to call us back about working on the project Monday the 27th though. Last, I personally have been helping all the guys with assembling machines ans attaching them to the board, and going to Lowes or other stores to buy material. I have also been brainstorming a lot of the ideas and figuring how all the individual pieces will work together.

C. We have taken into account and have started to build our energy transformations and simple machines. We do need to run through the checklist again though to make sure that we have done them correctly and have not forgotten a requirement.
