Today as scientists we made thoughtful predictions on what material a toy race car would travel down the fastest. Scientists recorded their predictions and then together as a class we tested our theories. We had a small ramp and four different materials. These materials included crepe paper, tissue paper, felt and textured fabric. We tested the car travelling down the ramp on all four materials. Using a stopwatch we recorded the exact time it took the car to travel from the top of the ramp to the bottom. After testing our theories we then recorded the results and and our findings on why the car travelled at different speeds.

Ask your scientist if they remember what force was involved in this activity.
