Designing an Experiment

What are the CONSTANTS in this experiment?

Find 5 adults and 5 kids willing to do as many push-ups as they can in one minute. Have each person start in a plank pose and give them a countdown before starting a timer. Count how many full push-ups each person can do in one minute. Let them know when a minute is up so they know when to stop. Compare the amount of push-ups completed and find the average for adults and the average for kids.

• The adults

• The kids

• Amount of time tested

• Number of push-ups

• Starting in plank pose
