Physics Runner vs. Bicyclist Speed Acceleration Lab

Are you looking for a fun lab with no prep to motivate your high school students to learn about graphing speed. Here it is!!
Upon completion of the lesson, students will be able to
Define acceleration and velocity.
Describe the differences between velocity and acceleration. Identify and utilize the formula for calculating the average acceleration of an object in given scenarios.
Students will go to the track and race a person against someone on a bike.
Your class will go out on the track and have a student do a 100-meter dash, recording their time at every 5-meter interval. (Have one person stand at each 5-meter mark and use their stopwatch.) Repeat that experiment, but with a bicycle starting from rest, in the highest (hardest to push) gear, and pushing with maximum force on the pedals.

After students collect the data, make one correctly labeled position vs. time graph which includes a curve representing the motion of each racer.
They will have the opportunity to learn about acceleration and make predictions if the track was longer.
