We used cars and different materials to find out the effects of each material on the speed of the cars. The materials we used were tissue, tinfoil and a tea towel. We discovered that the car moved slowest on the tea towel.

 

Then we used the cars with ramps to see how the angle of the ramp impacted on the speed of the cars. We found that the car moved fastest on the steepest ramp.

Science is fun!
