Conflicting Claims About the Effect of Exercise on the Rate of Clothespin Squeezing

* Hypothesis:
If a person does not exercise before to squeeze a clothespin, then they will be able to squeeze the clothespin more times in a minute than if they do exercise first. Without exercise the person will have more energy to squeeze the clothespin more times than the other who exercises first and might get tired more rapidly. * Materials:

* Clothespin
* Stop watch
* Pen or Pencil
* Paper to write down your results

* Methods:
Hold a spring-type clothespin between your thumb and index finger. Pinch the ends together completely (until the two ends touch) and release them. Do this rapidly as possible for one minute. Record the numbers of time twice without exercise and twice after been exercising. You must try the activity again, doing it the same way and using the same two fingers (thumb and index).

* Data Collected:
As it shows, in the table below the information collected from 3 students in Ms.Collins 3A-4 period Biology class. In which is showing the data after trying twice the same activity for one minute; in which it supports the hypothesis from the investigation. (With and without exercise) Dependent Variable Results

Name of the student| 1st time without exercise| 2nd time without exercise| Emilka | 120| 67|
Isabel| 144| 117|
Leyska| 149| 80|

Independent Variable Results
Name of the student| 1st time with exercise| 2nd time with exercise| Emilka| 100| 40|
Isabel| 120| 105|
Leyska| 111| 60|

* Discussion and Conclusion:
As my hypothesis was saying- If a person does not exercise before to squeeze a clothespin, then they will be able to squeeze the clothespin more times in a minute than if they do exercise first. The data table showed above does prove that when you exercise first you will get tired more easily than a person who does not exercise first and your number of squeezing will...
