Lumbriculus: Contraction Rate of the Dorsal Blood Vessel In this introductory physiology lab, students determine the contraction rate of the dorsal blood vessel of the blackworm Lumbriculus. Students then design and conduct an experiment to determine the effect of temperature change or chemical exposure on the contraction rate. View »
Daphnia Heart Rate In this introductory physiology lab, students determine the heart rate of Daphnia magna and then test the effect of changing temperature on the heart rate. View »
Modeling the Coriolis Effect The Coriolis effect can be a tough concept to explain, but it's fairly easy to model. Try this simple and inexpensive balloon activity. View »
