Today our science class did a ‘Scientific Method Bubble Gum Lab’.
What brand of gum is the best at blowing bubbles and why? Support your answer with observations and your data.
Big League Crew is the best at blowing bubbles. Hubba Bubba’s average bubble size was 21.5cm and Big League Crew’s average bubble size was 26.3cm. Blowing the bubble with Big League Crew was easier to blow the biggest bubble than Hubba Bubba, becuase it is soft and that made it stretch more.
How does gum stretchability relate to bubble size?
The bubble size depends on the gum stretchability. The stretchier the gum is, the bigger the bubble will be. Comparing the two gums, Big League Crew blew the biggest bubble and also it stretched out 617cm further than Hubba Bubba.
List 5 variables that may affect the outcome of this experiment.
- Mouth temperature
- Saliva
- Chewing time
- Bubble blowing capability
- How fast the person chew in a limited time
Explain how the data you collected can be described as both qualitative and quantitative
Observing the colour, shape, smell, and texture of the gum is a qualitative data. Measuring the length of the bubble and the length of the stretched gum is quantitative.
Were SI units used in this lab? Explain.
Yes, I used centimeter to measure the diameter of the bubble and the length of the stretched gum. I also used grams to weigh the gum.
