THE RACE TRACK: Practically any flat, unobstructed area will do, but in terms of convenience, the College Quadrangle will serve admirably. As noted in the figure below, which shows the center of the Quadrangle between Ingersoll and Boylan Halls, the distance between the concrete walkways in front of these two buildings is exactly 50 meters. Thus, by using, say, the Ingersoll sidewalk as the "start" of our race track, and the Boylan sidewalk as the "finish line" we have a race track of 50m length.

TEST PROCEDURE: To gather the necessary data, the test subject travels the length of the race track, i.e. from the Ingersoll to Boylan sidewalk. This is done, first at a walk, then with the test subject jogging, and finally at a run (but not "breakneck speed" - be careful).

Counters: Each time the test subject travels down the race track, several other members of the research team will count the number of strides made by the test subject in going from one end of the race track to the other. These results will be reported to all members of the class participating in the experiment.

Timers: Several additional members of the research team will act as timers. Their job will be to use the seconds dial on their wristwatches to measure the time needed by the test subject to traverse the race track. Results will be reported to all members of the class participating in the experiment.

PROCEDURAL ALERT: You will need to set up a signalling system so that timers will know exactly when the test subject starts moving along the race track, and when he/she crosses the finish line.
