JCE Classroom Activity
Popcorn—What's in the Bag?
Marissa B. Sherman and Thomas A. Evans
Department of Chemistry and Biochemistry, Denison University, Granville, OH 43023
Cover
March 2006
Vol. 83 No. 3
p. 416A
Abstract
Three independent activities explore microwave popcorn, the nature of the packaging, and the popcorn produced. The contents of the package before popping are examined to identify unique features of the packaging. (2) Popped popcorn is added to hot water to explore solubility behavior. (3) Mass loss on popping is investigated in a graphing exercise. The role of water is central to the results of each activity.

Featured on the Cover.

Supplement
A diagram of a popcorn kernel, a discussion of the starch–iodine test, additional questions to explore, and typical quantitative results are available.
