•A person will be able to squeeze a clothespin more times in a minute if the person exercises first.

Methods:

•Dependent variable- number of clothespin squeezes per minute

•Controlled variable- amount of time exercising and resting, number of trials, type of exercise, same type of clothespin , intensity of the exercise, and the age of test subjects

Materials:

•Clothespins

•Timer/stopwatch

•Paper and pencil

•Test subjects(students)

Both the table and the graph support that if a person exercises first , he/she will be able to squeeze a clothespin more times in a minute than a person who rests
