Cat. #AP10 Energy Dynamics
AP BIOLOGY INVESTIGATION 10
For 10 Groups. In this activity, students model how energy flows through a meadow ecosystem with an emphasis on the concepts of trophic levels and entropy. This is an alternative lab activity that does not require growing Brassica rapa or rearing the invasive pest, Pieris rapae . Following the exercise, students will be able to explain how biological systems use free energy, predict the effects of community changes on energy and nutrient flow, and apply mathematical equations to describe key abiotic and biotic interactions.
Requires 30-40 min.

Cat. #292 Dissolved Oxygen and Aquatic Primary Productivity
For 10 Groups. Dissolved oxygen levels are used to monitor the health and productiv- ity of aquatic ecosystems. In this kit, students familiarize themselves with the Winkler method by examining the relationship between temperature and dissolved oxygen concentrations. Using local water samples to examine primary productivity at different water depths, students can then observe the beginning stages of eutrophication.
Requires 2 hours.
