Davis, Lawrence C.; Chou, Nancy C.
American Biology Teacher, v60 n4 p281-84 Apr 1998
Presents some simple demonstrations that students can construct for themselves in class to learn the difference between diffusion and convection rates. Uses cabbage leaves and gelatin and focuses on diffusion in ungelified media, a quantitative diffusion estimate with hydroxyl ions, and a quantitative diffusion estimate with photons. (DDR)
