Investigating the Process of Diffusion Using an Analytical Puzzle
Villani, Philip; Dunlop, Rachel; Damitz, Brian
American Biology Teacher, v69 n7 p411-415 Sep 2007
The process of diffusion is described as the movement of a substance from an area of high concentration to an area of low concentration. In this article, the authors present a novel way to introduce students to diffusion through the use of an analytical puzzle. This exercise engages students in active learning through a thought provoking exercise that challenges them to evaluate the results of a complex demonstration, think critically about what it is they are observing, and formulate hypotheses for their observations. With some minor modifications, this simple demonstration could easily be developed into an investigative experience for students. (Contains 4 figures.)
