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.
