Students will explore friction using a simple machine and investigate how different materials create different amounts of friction.
MATERIALS
- 4 strips of cardboard, wood or other similar material (to make ramps)
- 1 to 4 toy cars (similar type / wheel size is best)
- 3 materials of different textures (e.g. sand paper, foil, towel, paper towel, plastic bag)
- Tape
- Books, blocks or boxes to prop up ramps (same objects for all ramps is best)
- Measuring tape and / or stopwatch (optional)
