Does Your Chewing Gum Lose Its Flavor?

Each learner chews a piece of gum until it loses its flavor, and then leaves the gum to dry for several days. By weighing the gum before and after chewing, they can determine the amount of mass lost which corresponds to the amount of sugar in the gum. Learners are then asked to design their own experiment to answer a question of their choosing related to the activity. Learners can follow this with a related activity: "How much Sugar is in Bubble Gum?" Resource contains detailed suggestions to assist learners who are designing their own experiment. Time requirement is intended to be spread over several meetings.

Materials List (per group of students)


  • a few sheets of aluminum foil (or small plastic weighing boats, if available)
  • a few permanent markers
  • one piece of gum per student; packaged bubble gum (e.g., Bubble Yum or Bubblicious brands) containing sugar works best for the initial experiment; use only one brand and flavor of gum for the whole class
  • several triple-beam balances accurate to 0.1 g (or electronic balances)
  • additional gum will be needed for the second set of student-devised experiments; amounts and types depend on what students choose to investigate
