  1. We had to change the design of the funnel in our project. The marble wasn't directly going into the funnel so we pushed the incline plane out from the board so that the ball can go into it without hitting it and falling out. 
  2. We have had some issues with keeping the pieces in place. If they move the slightest bit, the marble may not go onto the next step. It is a very touchy project and we have to get each component just right. 
  3. We have been able to incorporate some of the funnels and tubes into our design. Also, we have added in dominoes and PVC piping in order to make the path of the marble more complex. However, the majority of our project consists of simple machines. We also have a lot of stopping and starting of the marble as well as acceleration.

    What changes did you have to do to your original design and why?
    We half a quarter of the project done, and it only lasts 6 seconds. We are now working on ways to slow down our marble and stall for time. We added a side wall for support and more space. Our pulley system didn't work at first and we are still tinkering with it to make it work.
    B) What other challenges have you faced up to this point?
    B) Besides time, lack of supplies has slowed us down. The drills are almost never charged and someone always has the tool you need. Right now time is our biggest issue because we thought it would take longer for the marble to roll.

    C) Outside of simple machines and energy transfers, discuss two other physics concepts in detail that are demostrated in your project.
    First we have a pulley system that when activated by the marble sets off a mouse trap that has a string tied tightly to a lever that when released drops a marble onto our inclined planes, the tension of the string keeps the lever from dropping the marble early.
    Secondly, when we first drop our marble through a tube it comes flying out too fast and misses the corkscrew it's supposed catch on. To slow it down we put tape on the wood so the friction increases and gives our marble a better path to roll upon.
