What high school student wouldn’t love an experiment that requires the chewing of bubble gum? This lesson plan has everything you need to determine the percentage of sugar in bubble gum. Students need an understanding of the periodic table and an ability to calculate molar mass. They also need to use graphing techniques to analyze the data they collect. Included on the website are links to documents and a PowerPoint presentation that explains percentage composition. Address the national standard of scientific inquiry with this lesson, and remind your students to not put the chewed gum under their desks.
