After we have experimented with both types of gum to see which brand would blow a bigger bubble on average, we found that Gum A (Hubba-Bubba) had a longer bubble diameter than Gum B (Big League Chew). After 3 trials each, Gum A had an average diameter of 7.3 cm, whereas Gum B had an average diameter of 4.3 cm.

Then, we partnered up with another group and stretched the two types of gums to see whether the gum’s stretch-ability was related to the possibility of bubble sizes. Gum A was stretched to 2.8 m, whereas Gum B was stretched to just 0.6 m before it tore in two. With the data, we found that if the gum stretched more, the bubble size potential would be larger.

However, the data may be inaccurate as bubble blowing is always inconsistent. Also when blowing or stretching, there is also a bit of luck that takes part. If you’re lucky, then it stretches more. If you’re not, it doesn’t. Then as you’re chewing, the more you chew, the more your jaws get tired because of the constant chewing. Also, when chewing for long times, the condition of the gum starts to change, which alters the experiment. Finally, when measuring, the numbers might be inaccurate. It is difficult to accurately measure a bubble that pops after 2 seconds.

The data is both qualitative and quantitative because the observations of the gums are descriptive, therefore qualitative. Then the lengths of the diameters and gum stretched are specific lengths and measurable, therefore quantitative. The SI units used were cm for the diameter, grams for the weight measuring, and metres for the stretched gums.
