3. Students can now begin their experiment. One member of each student group should control the
s
pinning of the ride and the others should be responsible for making displacement marks on the
paper under the ride.
4. The student controlling the ride counts 10 teeth on the large yellow Gear and marks the 10th tooth
from their starting point with a water-based marker. The student then turns the original blue Gear
so it sits directly above this marked tooth on the large yellow Gear. The ride should be held in this
position as the new seat locations are marked.
5. The other members of the group place a dot on the paper under the new location of the seats that
are marked with masking tape. Label the new dots with ‘Y 2’ and ‘R 2’ respectively.
6. Repeat steps 4 and 5 a total of nineteen more times. Change the labels on the dots to reflect the
trial number (Y 3, R 3, Y 4, R 4, etc). This will allow the ride to make just over three rotations.
Caution: the individual that is counting teeth on the large yellow Gear will eventually reach a point
where s/he passes previously marked teeth. That student may choose to wipe off previous marks
or to be a very careful counter to avoid confusion.
7. When all points are marked, remove the ride from the paper and prepare to make measurements.
Students should prepare a data chart in their journals in which they will enter their measurements.

8. Students will:
a. Measure the distance from ‘Y start’ to ‘Y 2’ and, opposite Point #2, enter the value in centimeters
(cm) under the column labeled ‘Yellow Seat Displacement.’
b. Measure the distance from ‘R start’ to ‘R 2’ and, opposite Point #2, enter the value in centimeters
(cm) under the column labeled ‘Red Seat Displacement.’
c. Measure the displacement for each of the other points for the seat on the yellow Rod and the
points for the seat on the red Rod. Each measurement is always made from the start points.
