AP Chemistry Lab: Formula of a Hydrate | CED 1.3 | One Period
Give your students an authentic AP Chemistry laboratory experience— without giving up multiple class periods.This CED-aligned Topic 1.3 hydrate lab challenges students to use gravimetric analysis, mole ratios, and error analysis to determine the empirical formula and percent water of an unknown hydrate. How is this possible? Students work in pairs of two and split the investigation to simulate a real-world lab experience. Group A analyzes Epsom salt (MgSO₄·xH₂O) while Group B analyzes a dif

Strong Acid Base Reaction Simulation
Students begin by typing in their name so it appears on their screen at all times. This focuses strictly on the reaction of NaOH with an unknown concentration of HCl. Students complete 4 trials which includes adding the NaOH dropwise and measuring, recording, and graphing the pH change. After 4 trials students calculation the concentration of HCl using the chemical reaction and mol ratio and not the dilution equation to ensure better understanding. Students will receive feedback if they are corr

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
