Scientific Method Bubble Gum Lab (conclusion)

  1. How does gum stretchability relate to bubble size?

It doesn’t because even though Gum A formed a bigger bubble (for both groups), it was, in our experience, about 10 times shorter, when stretched, than Gum B.

2. 5 variables that may affect outcome;

  • Amount of each gum (A and B)
  • Amount of air/how quickly you blow into bubble
  • Number of chews
  • Time which each piece of gum layer out before chewing
  • Loss of substance (gum B stuck to the outside of mouth during procedure)
  • Mouth structure (if partner 1 chewed A and partner 2 chewed B)

3. Explain how the data you collected can be both qualitative and quantitative;

Two ways I could explain my results after stretching each piece of gum would be; B was stretchier and longer than A (qualitative), or B was longer than A by about 270cm (quantitative).

4. Were SI units used in this lab?

5. Yes, we used centimetres to measure the length/diameter of the gum throughout the lab.
