Winter Experiment Project Blog Post 2 (Results)

Conclusion:

Data Table:

**The initial height that the bouncy ball was dropped from was 36 inches**
**The bouncy balls were measured from being bounced on carpet**

Results:
From the data you can tell that my hypothesis was proven to be true. In my previous blog entry, I predicted that as you add more borax the bouncy ball will bounce higher.  The control, which contained 1/2 teaspoon of borax solution, bounced on an average of 11.90 inches when dropped from 36 inches off of the ground.  Then when I decreased the amount of borax solution, the average height the bouncy balls bounced was 11.10 inches off of the ground.  This proves that when you decrease the amount of borax, the height of the bounce decreases.  Likewise, when I increased the amount of borax solution to 3/4 teaspoons and 1 teaspoon, the average heights increased to 12.50 and 13.35, respectively. That proves that as you increase the amount of borax solution, the bouncy balls increase in the average height that they bounce when dropped from 36 inches above the ground.  All of the bouncy balls were bounced in the same place, on carpet, and by the same person.  This helped control the experimental conditions to receive more accurate results.

Before Experiment:

*This is a picture of the cups that were used to make the bouncy balls before they were actually made.
Bouncy Balls:

*This is a picture of the bouncy balls in their plastic bags.  They were kept in plastic bags because the more the bouncy balls are exposed to the air, the less bouncy they get.  So to receive better results, they were kept in plastic bags when they were not being used.
After Experiment:

*This is a picture of the cups that were used to make the bouncy balls.
Measuring the Bouncy Balls:

*This picture shows the location where the bouncy balls were measured for the height they bounced when they were dropped from 36 inches above the ground.  All 5 balls of each group were bounced once and then the average was taken of those 5 measurements for each group.
