AP® Environmental Science Beta
Tools
Environmental science trainers: calculations, energy flow, cycles, populations, soil, climate, energy, air and water pollution, toxicity and climate change.
Trainers
Work through a model or a representation, then answer questions about it.
- Calculation studioSetup, answer and units, each graded the way the readers grade them.Percents and Percent ChangeOpen
- Energy flowMove energy up a food chain and watch 90% leave as heat.Energy Flow and the 10% RuleOpen
- CyclesTap a process, then perturb a reservoir and watch the flows shift.The Carbon CycleOpen
- Population growthGrow a population to its carrying capacity, and past it.Population Growth and Resource AvailabilityOpen
- Age structureBuild a population pyramid and read its future.Age Structure DiagramsOpen
- Soil textureFind a soil on the texture triangle and see how it holds water.Soil Composition and PropertiesOpen
- Earth and climateMove through the year with the tilted Earth, then switch between El Niño and La Niña.El Niño and La NiñaOpen
- Energy chainFollow energy from fuel to outlet, step by step.Fossil FuelsOpen
- Air pollutionRun smog through a day and trap it under an inversion.Photochemical SmogOpen
- Water pollutionAdd fertilizer to a lake and follow the oxygen down.EutrophicationOpen
- Dose and responseRead LD50 off a curve and watch a toxin climb a food chain.Dose Response CurveOpen
- Climate changeKeep the greenhouse effect and the ozone layer apart for good.The Greenhouse EffectOpen
Every tool records what you answer: missed questions go into your review queue, and your accuracy shows here and on the dashboard.
