Problem:
Does prior exercise affect the ability to squeeze a clothespin?
Hypothesis:
After exercise, people will be able to squeeze the clothespin faster than those without prior exercise.
Materials:
For this experiment a timer and a clothespin were used.
Methods:
To begin this experiment an individual was asked to squeeze a clothespin as many times as possible within one minute and the results were recorded. Then this same individual was asked to exercise (run in place, preferably) vigorously for 45 seconds. After this period of exercise the same individual squeezed the clothespin as many times as possible within one minute and the results were recorded. At least 10 minutes later, a second trial was completed using the same exact steps, also recording data. These steps were done with 4 subjects separately. In this experiment the independent variable was the prior exercise and the dependent variable was the amount of times the clothespin was squeezed. The constants in this experiment included the amount of exercise, the time allotted to each individual to squeeze the clothespin and similar clothespins.
Results: Graph 1
This graph shows the differences in averages of the number of times the clothespin was squeezed with and without prior exercise.
Table 1
This table shows the data collected from each individual person. The data includes two trials of squeezing the clothespin in a minute without prior exercise and two trials of squeezing the clothespin with prior exercise. The data shows that, on average, the individuals were able to squeeze the clothespin more exercise with prior exercise.
Discussion:
The data directly supports the hypothesis. With a small margin of error it is fair to state that, in fact, prior exercise increases the number of times individuals can squeeze a clothespin, on average. Both the averages and the sub-averages of squeezing the clothespin with prior exercise were greater than those without prior exercise. This is
