This bundle includes everything you need to teach the biogeochemical cycles for AP Environmental (APES). More specifically 1.7 The Water Cycle (I teach this one first), 1.4 The Carbon Cycle, 1.5 The Nitrogen Cycle, and 1.6, The Phosphorous Cycle. If you are new to teaching AP Environmental Science or would like to revamp/spice-up your class, you will love these new, fresh PowerPoints that will keep your kids excited and engaged from beginning to end.What You Will Receive:1. 3 PowerPoint presenta
