Osmosis ~ Diffusion Biology Lab



There is simply no substitute for a good hands-on laboratory activity to teach and reinforce the concepts of science.  When science students "see it for themselves" they are much more likely to retain a long-term understanding of the concept.

This lab, "The Effect of Concentration on the Rate of Diffusion" will explore the concentration gradient in a number of "cells" of varying concentrations.  Students will use a variety of scientific method skills:  Observation, hypothesizing, data collection, graphing, and forming conclusions.

Best of all, this lab uses only simple lab equipment and it is FREE!
