Most of the flavoring in gum is due to the sugar or other sweetener it contains. As gum is chewed, the sugar dissolves and is swallowed. After a piece of gum loses its flavor, it can be left to dry at room temperature and then the difference between its initial (unchewed) mass and its chewed mass can be used to calculate the percentage of sugar in the gum. This demonstration experiment is used to generate new questions about gums and their ingredients, and students can then design and execute new experiments based on their own questions.

The engineeirng connection in this lesson is when students design experiments to test their hypothesis. Scientists practice engineering whenever they design new experiments to test hypothesis. students will be able to describe why a control is important in a scientific experiment students will be able to distinguish between variables and controls in a scientific experiment students will be able to describe an experiment to determine whether sugarless gum loses as much mass after chewing as regular gum does 5TeachEngineering.orgMary R.
