The results from this experiment concluded that the gum B was more stretchy and could blow bigger bubbles, thusly proving both hypotheses correct.

In part one, we hypothesized that the squishier gum would blow a larger bubble. Gum B was was squishier than Gum A, although this may be because Gum B was in one solid piece, not broken up like Gum A. After two minutes of chewing both kinds of gum, we blew three bubbles each to determine which one blew bigger bubbles. This part of the experiment is a variable because one of us may have been not as good at blowing up bubbles as the other, therefore affecting how the data turned out. In the end, The average size of bubble produced by Gum A was 5.6cm, whereas the average size of a Gum B bubble was 8.2cm. Based on this small sample size, we can conclude that Gum B effectively produced larger bubbles than Gum A, although it cannot be directly correlated with its squishiness.

In part two, we tested the stretchiness of two kinds of bubble gum.  Our hypothesis stated that Gum B would outstretch Gum A because of it’s higher ability to hold a growing bubble of air. Using tin foil and our chewed up gum, we stretched the gum across the classroom to reach over 10m. Due to space restrictions, we could only get the gum to stretch 10m, but based on how much it was stretching, I speculate that it could’ve stretched at least 2m more. Gum A, on the other hand, only stretched 4m.

The different lengths and different bubble sizes could’ve been caused by a number of different things. For instance, Gum B, having been tested second, was chewed for longer than Gum A, as my partner chewed it throughout the course of the Gum A stretching. Moreover, the fact that Gum A, or Big League Chew, is sold in shredded pieces, could’ve contributed to its overall elasticity when chewed. The gums, while seeming very similar, could have been made from a world of different materials. The chemicals and other ingredients used can contribute to all parts of the gum stretchiness.

In conclusion, the hypotheses tested proved true, however, the reasons supplied behind why they worked can vary, and may not be correct due to many different variables playing a part in this experiment
