Inspired by Dale Basler’s stop-motion video project in physics, I recently had my freshman biophys students make videos that examine the factors affecting the rate of a chemical reaction. We used a lab from an Addison-Wesley Chemistry lab manual entitled “Factors Affecting Reaction Rates”. This lab was ideal, as the instructions are already neatly divided
Teaching abstract concepts in science is often challenging. One concept that my life science students have difficulty with is osmosis. Osmosis is hard to conceptualize, and many students do not seem to understand the concept even after the standard lab experience. Consequently, I began trying to think of how I could approach this concept differently.
