Conclusion:
Our two hypothesis ended up having opposite results, Gum A resulted in a bigger bubble size but Gum B had more of an ability to stretch. Our first hypothesis was for what brand of gum will be the best at blowing bubbles. “If we chew both pieces for 3 minutes each, then Gum A will blow bigger bubbles because it is thicker” We then tested both brands and recorded our data. We recorded 3 trials for each piece of gum. The average size bubble for Gum A came to 10cm and Gum B came to 3.25cm. We concluded that Gum A was the best at blowing bubbles because it was thick and did not easily break. Our next hypothesis was for gum stretch ability. “If the gum is stretchy then the bubble will be bigger because it will not easily break” Our data showed that Gum B had more ability to stretch. When we tested its ability it stretched to 130cm and Gum A stretched to 49cm. Gum B was able to stretch more in part 2 of our experiment because it was more of a stretchy texture oppose to Gum A which was thicker. Since Gum A’s texture was thick, it made its ability to stretch harder and it didn’t stretch as far as Gum B. When blowing bubbles, Gum A was the best since its texture was thick and didn’t break easily. I think our hypothesis should be refuted because of the opposite results. The 5 variables listed below could have affected our results greatly.
Some variables that may have affected our outcome of this experiment:
- The number of times the gum was chewed by each person in 3 minutes. If it’s not the same, it can affect the results.
- Having different chewing techniques (speed, etc.)
- The speed of pulling in part 2. The person could have been walking back faster while testing Gum A than Gum B
- Ability in blowing bubbles
- More tests with part 2. We could have averaged it and found a better answer.
Qualitative: Our observations to help write our hypothesis and conclusions.
Quantitative: Recorded our data of the size of bubbles and the length the gum stretched using table graphs.
SI units: There were SI units used in this experiment, centimeters, and grams. We used centimeters to measure the size of the bubble and the length the gum stretched. Also used grams to weigh the gum before we began.
