Sound Pollution Assessment Lab

Created by

Sound pollution, or noise pollution, is unwanted or harmful sound that disrupts the environment. The decibel (dB) scale measures sound intensity logarithmically, meaning each 10 dB increase represents a tenfold increase in sound intensity. Prolonged exposure to sounds above 85 dB can cause hearing damage, while levels above 120 dB can cause immediate harm. Smartphone apps use the device's microphone to estimate sound levels, but their accuracy can vary based on microphone quality, calibration, a

Biomagnification Calculations Lab (APES Unit 8) DDT/Mercury + FRQ + Key

Created by

Allison Smith

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
