- Place the first material on the ramp.
- Place the toy car at the top of the ramp.
- Release the car.
- Measure how far the car travels.
- Record the results in the table.
- Repeat the test for each material and record the results.

No. This variable cannot be controlled.
Yes. This variable should be kept the same as it will affect how far the car travels.
Yes. This variable should be kept the same as it will affect how far the car travels.
No. This variable does not need to be kept the same as it does not have an effect on the distance the car travels.
