Part of Dimensional analysis - Classroom Activities

Part 2 of 2

Highlights: An extended groupwork activity on the HP equation that can help students get a handle on dimensional analysis. Includes a little calculus.

Abstract: This groupwork activity has students work through a moderately complex problem in dimensional analysis relevant to biologists: Debye shielding of charge in an ionic fluid. The lesson is highly scaffolded without being algorithmic. Appropriate either for a recitation or a large lecture class with groupwork structures available. Also could be given as a homework problem.
