This week in Science, we conducted a comparative test to answer a question: How does the material under the wheels affect the distance a car can travel?
First, we discussed what different forces might act on the toy cars to make them move.
Then, we selected lots of different materials, attached them to a ramp, and placed toy cars on them. After that, we identified how the surface affected the car by measuring the distance travelled from the bottom of the ramp.
We used rulers and meter sticks to measure the distance accurately. To make our test fair we kept everything the same except for the surface we were testing.
We found out that the material under the wheels has a significant effect on the distance a car can travel. The rough, bumpy surfaces slowed down the movement of the car.
