Cell Biology Labs
Our simulated cell biology labs let students visualize and tinker with processes at the molecular level, complementing wet lab experiments where they can only see macro-level phenomena. Developed with National Science Foundation funding to study and address student misconceptions, OsmoBeaker® guides students through experiments to see how interactions between molecules lead to diffusion and osmosis. Our research shows this approach leads to improved understanding (Meir et al, 2005). The Mitosis & Meiosis interactive tutorial includes innovative elements that help students study and understand confusing aspects of these important processes.

OsmoBeaker: DiffusionThis 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: OsmosisThis 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. ...
