Abstract:The purpose of this experiment is to see if the number of times somebody closes a clothespin increases with or without exercise.It is our hypothesis that if you rest first then you should be able to squeeze clothespin more times in one minute then squeezing the clothespin with exercise. In our experiment one person exercised for two minutes and then squeezed the clothespin, then after the one minute they rested then squeezed the clothespin. Our hypothesis was proven correct since the person squeezed the clothespin more after he rested. …show more content…

•While exercising your lungs tries to increase the intake of oxygen as well as release the carbon dioxide.

Hypothesis: If you rest first, then you will be able to squeeze a clothespin more times in one minute.

Materials

•Timer

•2 clothespins

•One person

Procedure

Step 1:Get a timer, 2 clothespins, and 1 test subject

Step 2:Let the test subject do jumping jacks for 2:00 minutes.

Step 3:Set a timer for one minute.

Step 4:Make sure the person holds the clothespin between their thumb and index finger and squeeze until the two ends meet.

Step 5:Start timer and have the person squeeze the clothespin for one minute.

Step 6:Record how many times the clothespin was squeezed.

Step 7: Then let the person rest for 2:00 minutes

Step 8: Repeat steps 4 through 6

Step 9: Compare the data from both trials

Step 10:Repeat experiment to get more accuracy

Variables:
