Gum A was Hubba Bubba. I found this gum was a lot thicker, and less smooth. This allowed it to hold a bubble easier, but it wasn’t very stretchy, so it didn’t blow very big bubbles.
Gum B was Big League Chew. I found this gum was smoother and very thin, making it easier to blow a big bubble but the bubbles popped very quickly. Since it was thinner, it stretched further than gum A.
How does gum stretchability relate to bubble size?
After comparing data, we found that Big League Chew stretched further and blew the bigger bubble. It makes sense that the stretchier one would make a bigger bubble, since it allows it to expand further when you blowing a bubble.
With your lab partner, list 5 variables that may affect the outcome of this experiment.
- If you chewed the gum for the same amount of time for each piece
- If you have the same amount of gum from each brand
- How long ago the gum was chewed before stretching it. (Ours was sitting out for a while, allowing it to not be stretched very easily)
- If the same person chewed both pieces
- How well someone can blow a bubble
Explain how the data you collected can be described as both qualitative and quantitative.
The data we collected can be described as quantitative from when we measured the circumference of the bubble and the length from how far the gum stretched. It can be described as qualitative by describing the colour of the gum, the shape, the consistency, and how it smelt (characteristics).
Were SI units used in this lab? Explain.
Yes, they were used to weigh the gum, since we weighed them in grams. We also used SI units when we measured the size of the bubble and the length the gum stretched, since we measured them in centimeters.
