Biomagnification Calculations Lab (APES Unit 8) DDT/Mercury + FRQ + Key
Biomagnification shows up on the APES exam almost every year—and students often miss the math and the “why.” This AP Environmental Science activity fixes both. Students complete progressively rigorous toxin calculations through real food chains (DDT + mercury), calculate bioaccumulation factors (BAF), analyze a graph showing exponential increase, and finish with AP-style FRQ practice plus real-world policy evaluation (DDT ban, Minamata disease, mercury advisories, PCB cleanup). ✅ Mirrors t

Quiz on Chapters 7-8 of Lois Lowry's The Giver
This is a brief, 7-question quiz on Chapters 7-8 of Lois Lowry’s The Giver. It is meant as a quick check of comprehension shortly after the chapters have been read, so it asks only fact-based questions about plot, character, and setting. No analysis or interpretation is expected. Taking and reviewing the quiz at the beginning of class serves as an excellent transition point into a deeper discussion of the chapters. Of the seven questions on the quiz, THREE are open-ended and can be answered wel

IB DP Environmental Systems & Societies Lab - Soil properties
Lab activity for ESS topic 5.1
Students are introduced to 3 different methods to classify soils and determine their moisture and organic (carbon) content.
Soil classification uses the gravimetric method of placing soil samples in glass gas flasks or graduated cylinders with water, shaking it well and letting the particles fall out of suspension and determine boundaries between sand, silt and clay. These then are plotted on tri-linear soil classification diagrams.
