Gum Chewing Experiment: Mass Changes in 10 Minutes

Explore what happens to the mass of gum after it is chewed for ten minutes. This experiment focuses on constants, team involvement, accurate weighing, proper units of measurement, and correct mathematical calculations. Learn how to create effective graphs and double-check your plots. Additional enrichment includes cost analysis and determining which gum offers the best value for money. Consider the validity of the experiment and document your work in your science journal.

Presentation Transcript

  1. By Golly, By Gum!

  2. What happens to the mass of gum after it is chewed for ten minutes?

  3. Constants • The things that stay the same in the experiment

  4. Chew on this….. • Are all team members actively involved? • Are you weighing correctly? • Are you listing units of measurements on your data table? • Is your math correct?

  5. Don’t let graphs blow you away! • Double check your plots. • Make sure your spacing is correct. • Subtitles need to be labeled. • http://nces.ed.gov/nceskids/graphing

  6. Enrichment • Cost Analysis • How can you find out which gum gives you the best “bang for your buck?” • Please show all of your work in your science journal • Was this a valid experiment? Why or Why Not?
