Polymer Lab Group Investigation

My group decided to take a different spin on the original polymer lab we had done with the Elmer's Glue and the Borax. The way we changed this lab, was by making two different polymers, one with 50 percent more glue (60ml), and one with 50 percent less glue (20ml) than the original amount (40ml). The problem her was, the polymer became saturated, so unfortunately, the smaller amount of glue made no difference due to it not absorbing all of the borax. We decided to just test the polymer with more glue, due to there being a different mixture with more glue and absorbing more borax.

To stay consistent, we still used a quarter sized ball, and tested the rebound... here are the results: The original ball we made had bounced an average of 14.8cm per bounce. When more glue was involved, the ball bounced a considerable difference of 2.7cm, being at an average 17.5cm. Also, when chilled, the ball improved another .3cm than when room temperature, although the ball bounced inconsistent, probably due to the oddly shaped ball from sitting in the fridge for ten minutes.

What we pulled from this experiment was that with more glue involved, the polymer felt more solid, which probably made the ideal "bouncy ball" that obviously made it bounce higher than before. Also, when chilled, the ball became slightly more solid, which also probably helped the rebound of the polymer.

Here you can see the bigger polymer (60ml glue) to the right already formed and in ball shape, and the smaller polymer (20ml glue) still being formed to the left.
