OsmoBeaker
The Osmosis and Diffusion labs in OsmoBeaker® use simulated molecular-level experiments to explore some of the trickiest concepts for introductory biology students to understand, helping them overcome common misconceptions. These labs use medically relevant examples that allow students to visualize and tinker with the mechanisms underlying diffusion and osmosis. Our National Science Foundation funded research shows that students understand these critical processes better after using OsmoBeaker (Meir, et al. 2005) .
OsmoBeaker Labs
OsmoBeaker: Diffusion
This lab confronts common misconceptions about diffusion using engaging simulated molecular-level experiments. The lab first focuses students' attention on how individual molecules move under different conditions. It then sets up a fun experiment that allows them to explore whether nerve cells could use diffusion to move materials from the cell body to the synapses at the tips of their axons. ...

OsmoBeaker: Osmosis
This popular lab places students in the role of a doctor providing intravenous fluids to a patient. They must compose an intravenous fluid that does not cause the patient's red blood cells to expand or shrink. Using simulated cells, students explore osmosis with no, one, two, and many solutes. ...
