Test #1

Hypothesis: If thread is used to pull back the hanger attached to the mouse trap, then it will unwind at an even pace

Procedure:

1. Cut an appropriate sized (in length) piece of thread
2. Tie thread through the hook attached to the hanger
3. Pull back thread and attach to axle
4. Wind the axle back
5. Let go of axle

Results:

As the thread was released, it unwinded slowly. Also, as it was unwinding the thread got tangled and slowed the car down.

Conclusion:

The results showed that the hypothesis was incorrect. The thread did not unwind at an even pace but rather got tangled and slowed the car down. The acceleration was negatively impacted overall by the thread. This leads to the conclusion of using fishing wire instead of thread.
