Free, College Board–aligned digital laboratories that connect environmental science concepts to real human impact. Every lab blends reading, data, simulation, and AP-style FRQ practice across all nine curriculum units.
Labs follow the College Board's AP Environmental Science curriculum framework. Each unit emphasizes data analysis, mathematical reasoning, and human-environment interactions.
Energy flow, biogeochemical cycles, and ecosystem services
Species diversity, ecological tolerance, and ecosystem resilience
Sample two habitats with virtual quadrats, calculate Simpson's Diversity Index, analyze a case study, and tackle APES-style free response questions on biodiversity and habitat fragmentation.
Compare predation, competition, symbiosis, and parasitism using real-world case studies.
Population dynamics, demographics, and human population growth
Apply the Lincoln-Peterson Index to estimate population size in a virtual pond. Test the assumptions of the method, analyze a salamander case study, and battle the Mark-Recapture Boss.
Compare exponential vs. logistic growth, calculate doubling time using the rule of 70, and predict carrying capacity.
Interpret age-structure pyramids and link the demographic transition model to economic development.
Plate tectonics, soil, atmosphere, and global wind patterns
Agriculture, mining, fishing, urbanization, and ecological footprints
Compare industrial monoculture, sustainable agriculture, and the Green Revolution's costs and benefits.
Quantify forest loss, model carbon release, and evaluate reforestation as a climate solution.
Calculate ecological footprint, examine urban heat islands, and design more sustainable city plans.
Fossil fuels, nuclear energy, renewables, and energy efficiency
Compare energy density, cost, and emissions across coal, oil, gas, solar, wind, hydro, and geothermal sources.
Calculate household kWh usage, identify efficiency upgrades, and project annual cost and CO₂ savings.
Model fission reactors, compare risks at Chernobyl and Fukushima, and weigh nuclear vs. fossil emissions.
Air quality, smog, acid deposition, and indoor air pollution
Water pollution, solid waste, pesticides, and bioaccumulation
Sample three Long Island sites (pond, stream, bay) for pH, DO, nitrates, phosphates, and turbidity. Calculate a composite Water Quality Index, analyze the Great South Bay Brown Tide collapse, and graph nitrogen loading in Moriches Bay.
Run a serial-dilution radish-seed bioassay, build a sigmoidal dose-response curve, calculate LD50, and analyze the Atrazine-and-frogs case study on sub-ppb endocrine effects.
Track DDT and mercury concentrations up a food chain and predict top-predator health impacts.
Examine ocean and river plastic patches and evaluate river-removal and ocean-removal cleanup methods.
Climate change, ozone depletion, ocean acidification, and mitigation strategies
Analyze Keeling Curve data, model greenhouse gas forcing, and predict warming under different emissions scenarios.
Trace CFC chemistry in the stratosphere and evaluate the Montreal Protocol's success at restoring the ozone layer.
Investigate how rising CO₂ lowers ocean pH and threatens coral reefs, shellfish, and marine food webs.
