We sit up a ramp that was 10.9 cm high and 34.4 cm long. We had playdough where the two ramps meet and the ramps went to the end of the table. We released a steel ball from the top of the ramp and let it fall of the table and hit the floor. We used carbon paper to determine where the ball hit the floor first. We then measured from the edge of the table to the spot to see how far the ball had went. We had 5 trials and took the average of the 5 trials for our point.
