Grade 12 Environmental Science
A senior year built around one question: how do humans affect the planet, and what should we do about it? Across 36 weeks you build the framework - Earth systems, ecology, energy flow, biogeochemical cycles - then apply it to the biggest issues of our century: biodiversity loss, climate change, energy choices, pollution, and policy. Tap-only on phone or tablet; nothing to type.
Earth Systems and Human Impact
- Week 1 - Earth as a system. Four spheres. Water cycle. Atmosphere. Biomes.
- Week 2 - Ecology. Populations, communities, keystone species, invasives.
- Week 3 - Energy flow. Producers, consumers, decomposers, the 10% rule.
- Week 4 - Biogeochemical cycles. Carbon, nitrogen, phosphorus, water, sulfur.
- Week 5 - Biodiversity. HIPPO threats. Conservation. Ecosystem services.
- Week 6 - Climate change. Greenhouse effect, consequences, mitigation, Paris Agreement.
- Week 7 - Energy resources. Fossil fuels, nuclear, renewables, efficiency.
- Week 8 - Pollution. Air, water, land, ocean acidification.
- Week 9 - Environmental policy + sustainability + Q1 synthesis at 85% mastery.
Ecosystems Deep Dive

- Year synthesis - one interactive sequence reviewing the year (no paper).
Self-paced and self-checked. Every activity is auto-graded by the runner; there is no human or AI grader. Mastery is reached when you can do the tap-mechanics for a week reliably.
