What amount of glue makes slime bounce the most?
Problem
What amount of glue makes slime bounce the highest?What Amount of Glue Makes Slime Bounce Highest?
Hypothesis
My hypothesis was that the slime with the most glue would bounce highest.
Procedure
Follow online recipe for slime, making four distinct batches
Put a different amount of glue in each batch of slime
Roll each tablespoon of slime into a neat ball
Calculate bounce height by taking a slow motion video of the test and recording the number at the peak height of the bounce.
Record data in log
Conclusion
My hypothesis turned out to be incorrect, because it happened that the slime with the least amount of glue bounced highest each time instead of the most as I originally thought. I do think my experiment was as accurate as possible because of the way I observed the data itself; Taking a slow motion video of each test provided a better way of being able to record the data. In the future if I were to expand on this topic I would test more batches of slime to get a more varied and accurate reading.
Abstract
For my science fair project I tested what amount of glue makes slime bounce the highest. My hypothesis was that the more glue was added to the mixture the higher the slime would bounce. I thought this because in making slime, glue is what gives it its structure and keeps it together. The reason I chose to test this is because I have previously made slime for fun and wanted to see if there were any scientific discoveries to be made while also having a good time.
My experiment consisted of four tests, each with slime of a different color and a different amount of glue used when making it. The different slimes were dropped three times from a height of 30.48 centimeters, or one foot. To ensure I captured precise measurements, I took a slow motion video of each set of tests with each different slime, recording the data when the slime reached its highest peak in the air. In order to see the numbers clearly, I taped a ruler to a piece of posterboard and wrote the numbers on the poster board larger so I could make sure I was definitely getting the correct number.
For the first set of tests, using the blue slime, made with ½ cup of glue, the data reads that the average for all three tests was 9.7 centimeters. The second test, with purple slime, using ⅓ cup of glue, concluded that the average height for this slime was 8 centimeters. The third color slime I tested was yellow slime, and I used ¼ cup of glue to create it. This slime bounced an average of 20.7 centimeters over three tests. Lastly I tested a green slime made with 1 full cup of glue. The average of the heights for this slime was 17.3 centimeters.
My hypothesis turned out to be incorrect; instead of the slime with the highest glue content bouncing the highest like I had originally thought, the slime that had the lowest amount of glue won out in the end. This was due to the ratio of Borax and water to glue since all I changed was the amount of glue for each test. This is proved by the fact that my hypothesis was that the slime with one full cup of glue did not bounce as high as I had thought it would, averaging only 17.3 centimeters, while the slime with the least amount of glue, ¼ cup, bounced highest at an average of 20.7 centimeters. To improve this experiment in the future I would have done more tests on each slime and done different variations in slime; for example, ten different slimes as opposed to four. I also would have attempted a more precise way to measure the data.
