Test #2

Hypothesis: If CD's are used as wheels, then the vehicle will follow a straight path

Procedure:

1. Insert pen through 2 CD's
2. Hot glue the CD's to each side of the pen evenly
3. Glue pen and CD's (wheels and axles) to vehicle
4. Repeat steps 1-3 for other set of wheels

Results:

When the car was released, the CD's allowed the vehicle to move in a straight, steady path. It also helped the car move faster and smoother. 

Conclusion:

The hypothesis was proven correct. One of the rules for this assignment states that the vehicle must stay in a 2 tile wide path. Using CD's will be an advantage since the CD's allow the car to move in a straight path. Overall, it had a positive impact on the vehicle leading to the conclusion of using CD's as wheels.
