Answer:
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.
EXPERIMENT
1
Locate a large level surface on which to perform the experiment.
2
Place the ramp on the floor and mark where it is to ensure it has the same starting point for all rolls.
3
Hold the marble at the top of the ramp and release it.
4
When the marble comes to a stop, mark its position with a piece of red tape labeled “wood 1.”
5
Repeat Step 3 and mark the marble’s stopping position with yellow tape labeled “wood 2.”
6
Repeat Step 3 and mark the marble’s stopping position with a piece of green tape labeled “wood 3.”
7
Cover the ramp with the towel and repeat Steps 3-6, labeling the tape “towel.”
8
Repeat Step 7 for the sandpaper, wax paper, paper towel, cling wrap, foam and foil, marking the name of each covering on the different colored tapes.
9
Measure from the base of the ramp to each piece of tape and record the measurements for the first, second, and third rolls on each surface.
10
- Calculate the average distance rolled for each surface and graph the results.
