Another Look at the Fizz Keeper: A Case-Study Laboratory Exercise for High School Students
Mekelburg, Christopher R.; Szczepankiewicz, Steven H.; Hellerer, Matthew
Journal of Chemical Education, v87 n7 p705-707 Jul 2010
This case study places the high school student as a researcher for Carbonation Creators (fictional entity), a company responsible for making the Fizzy Forcer (a device to improve carbonation in previously opened bottles of soft drinks). The company faces a class-action lawsuit claiming that the Fizzy Forcer does not retain carbonation levels in previously opened bottles of soft drink as promised. The company invites the student to test the Fizzy Forcer. The case and laboratory exercise introduce LeChatelier's principle with a guided laboratory procedure and help to clarify some of the common misconceptions surrounding chemical equilibrium. (Contains 3 notes and 2 figures.)
