Purpose:
Which brand of bubble gum, Gum A (Hubba Bubba) or Gum B (Big League Chew), can produce the largest bubbles.
My partner (Alyson) and I first hypothesized which bubble gum would produce larger bubbles and we both agreed it would be Gum A (Hubba Bubba). Next she started chewing both gums and blowing bubbles while I measured the size in circumference. In conclusion, the data did not support my hypothesis that Gum A (Hubba Bubba) produced larger bubbles in circumference (20.7 cm) than Gum B (Big League Chew) (19.3 cm). This was because the difference between the average bubble size was not significant enough to say Gum A produced larger bubbles. The reason for that is because the Standard Deviation (2.5 cm and 1.5 cm) between the measurements was larger than the difference between the two averages and therefore is not significant enough to say one was significantly better than the other.
Next we Hypothesized that the stretchier gum would produce the larger bubble although both bubbles were very similar in size. We than tested gum stretchability by pulling the gum from two sides and slowly backing apart measuring the length before the gum snapped. The data we collected showed that Gum B (133 cm) was stretchier in length almost by three times than Gum A (55 cm). I cannot determine if my hypothesis is correct or not because in theory the stretchier gum would produce larger bubbles but the Stretchier Gum (Gum B) did not produce larger bubbles, they produce almost the same. This may be because both gums were stretchy enough to produce about 20 cm sized bubbles, or perhaps my partner was not capable of blowing any larger bubbles and that is why we could not see any significant difference between gums. Maybe if we had someone else who was capable of blowing larger bubbles, than we might see that Gum B could produce larger bubbles. Another reason why the gum stretchability did not correlate with the bubble size could maybe be because we may not have done enough tests both for bubble size and stretching. If we took more measurements than maybe we would have seen one gum was significantly larger than the other and if Gum A (being significantly less stretchy) could have been comparable with Gum B.
