Product Description
Students investigate change in mass of bubble gum over ten minutes of chewing time. Graph shows a sharp exponential drop in mass at first, followed by a leveling out of mass loss. The lab helps students relate the sensory experience of flavor change to the shape of a graph.

Cause and effect (independent and dependent variables) are analyzed in this controlled experiment, and then graphically represented and communicated.

Extensions include hypothesizing the data that would emerge from samples of chewing gum.

This lesson easily relates to NGSS Crosscutting Concepts of cause and effect, as well as designing and investigating a problem. Can be easily modified to suit grade level.

A "Gum Lab Assessment" is also an available product.
