AP Environmental Science study plan

AP Environmental Science · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Global Change

  • Explain how increased atmospheric greenhouse gas concentrations alter Earth's energy balance and global mean temperature

  • Distinguish among positive and negative feedback loops in climate systems and predict their net effect on warming

  • Interpret the causes and consequences of sea level rise, including thermal expansion and ice sheet loss

  • Compare the relative contributions of different greenhouse gases to radiative forcing

Your checkpoint

A one-page concept map linking greenhouse gas sources, radiative forcing, feedback loops, and at least four documented global-change consequences

Week 2

Global Change & Atmospheric Pollution

  • Analyze how climate change shifts species ranges, phenology, and ecosystem services

  • Connect global change to ocean acidification chemistry and calcifying organism impacts

  • Identify major greenhouse gas sources by sector and evaluate one mitigation strategy per sector

  • Trace the formation and environmental effects of tropospheric ozone and photochemical smog

Your checkpoint

A 12-question self-made practice set on global change and atmospheric pollution with worked answer explanations

Week 3

Populations

  • Calculate population growth rates using birth, death, immigration, and emigration data

  • Distinguish exponential from logistic growth and identify carrying capacity in given scenarios

  • Interpret age-structure diagrams to predict future population trends

  • Explain demographic transition stages and their associated birth and death rate patterns

  • Relate population growth to resource consumption and environmental impact

Your checkpoint

A solved problem set of 10 quantitative population calculations, including at least three age-structure interpretations

Week 4

Earth Systems and Resources

  • Describe the rock cycle and distinguish the formation processes of igneous, sedimentary, and metamorphic rock

  • Explain plate tectonic processes and their association with earthquakes, volcanoes, and mineral distribution

  • Analyze soil formation, horizons, and the causes of soil erosion and salinization

  • Trace the water cycle and explain how groundwater withdrawal and recharge interact

  • Identify the properties and formation of key nonrenewable and renewable soil and mineral resources

Your checkpoint

A completed 25-question mixed-format quiz on Earth systems and resources, scored with a written error log

Week 5

Energy Resources and Consumption

  • Compare the energy density, emissions, and availability of fossil fuels and renewable sources

  • Calculate energy efficiency and energy return on investment for given scenarios

  • Explain the environmental impacts of extracting, processing, and combusting each major fuel type

  • Evaluate the trade-offs of nuclear power, including waste storage and accident risk

  • Recommend a regional energy portfolio justified by resource availability and environmental constraints

Your checkpoint

A written comparative analysis recommending an energy mix for a hypothetical region, with quantitative justification

Week 6

Land and Water Use

  • Classify land use types and evaluate the sustainability of agricultural, forestry, and urban practices

  • Analyze the causes and consequences of deforestation, desertification, and urbanization

  • Explain irrigation methods and their associated waterlogging and salinization risks

  • Evaluate fishery management and aquaculture practices against sustainability criteria

  • Compare integrated pest management with synthetic pesticide use in terms of environmental outcomes

Your checkpoint

A land-use case study write-up applying at least four sustainability criteria to a single hypothetical region

Week 7

Aquatic and Terrestrial Pollution & The Living World: Ecosystems

  • Identify major point and nonpoint sources of aquatic pollution and their effects on dissolved oxygen

  • Explain biomagnification and bioaccumulation using a food chain example

  • Distinguish primary, secondary, and tertiary wastewater treatment processes

  • Describe the pathways and health effects of major terrestrial pollutants, including heavy metals and persistent organic pollutants

  • Trace energy flow and nutrient cycling through trophic levels in an ecosystem

Your checkpoint

A labeled diagram and written explanation of a pollutant's path from source through treatment or environment to a human health effect

Week 8

The Living World: Biodiversity & The Living World: Ecosystems & Global Change

  • Compare species richness, evenness, and ecosystem resilience across given examples

  • Explain the causes and consequences of habitat fragmentation and invasive species

  • Evaluate biodiversity conservation strategies, including protected areas and restoration

  • Synthesize content across all nine domains by mapping each to its recurring exam themes

  • Diagnose and correct remaining weak areas identified from prior practice results

Your checkpoint

A full-length timed practice exam completed under test conditions, with a prioritized review list of remaining weak domains
