Conclusion:

After making our observations about each bubble gum we hypothesized that Brand A (Hubba Bubba) would make bigger bubbles because of its harder texture which we thought should make the gum stronger and not pop as easily. We began the trials which afterwards proved that Brand A made bigger bubbles. For the next part we hypothesized that if Brand A’s bubble size was larger then the stretch ability should be longer too because it is more durable. After the trials we saw that Brand A also had better stretch ability. So, both hypothesis’s were supported. Finally we concluded that if bubble gum makes large bubbles then the stretch ability will also we good because of the strength of the gum.

We also listed 5 variables that could have affected the outcome of this experiment. First the texture whether the come was soft or hard. How well the bubble was blown because in some trials you could have just not blown the bubble as well as you could have. Then how much the gum was chewed. Maybe she chewed one gum more or faster then the other making it tougher? Another variable could be the number of trials because maybe with more trials the averages could have changed a lot. Then also how long the gum sat and hardened before actually testing the stretch ability.

Our data can be described as qualitative because of our observation of the texture and appearance of them gum but it can also be described as quantitative because of the measurements of the bubbles diameter and length of how far it can stretch. SI units were used in this lab like centimeters and grams. We measured the diameter of bubbles and length of the stretched out gum with centimeters and weighed the gum with grams on the scale at the start of the lab.
