The purpose of this experiment is to find out whether the texture of a surface will affect the distance rolled by a marble, and if so, which ramp surface a marble will roll the farthest on.
- Wooden ramp with beveled end and a channel down the center
- 1 marble
- Lengths of textured fabric, cut to fit the ramp (cloth towel, paper towel, foil, sandpaper, wax paper, cling wrap, foam)
- Red, yellow, and green masking tape
- Permanent marker
- 50' measuring tape
