Goal: Base Nacional Comum Curricular (BNCC), Ensino Fundamental: Ciências (Science), 7º ano

## 1. Science

- [Body Temperature Regulation](https://ai.page/c/body-temperature-regulation/index.md): Explain how the human body detects and responds to environmental changes including temperature, including the role of the skin in temperature regulation (sweating, shivering, vasodilation, vasoconstriction)
- [Conduction, convection, and radiation](https://ai.page/c/conduction-convection-and-radiation/index.md): Describe and compare the three mechanisms of heat transfer — conduction (particle vibration through solids), convection (fluid movement in liquids/gases), and radiation (infrared waves) — and explain that the rate of transfer depends on temperature difference
- [The Biodiversity Crisis](https://ai.page/c/the-biodiversity-crisis/index.md): Quantify the current biodiversity crisis: extinction rates 100-1000x the background rate; explain methods for measuring biodiversity loss (species-area relationship, population viability analysis, IUCN Red List categories); evaluate rewilding case studies — Yellowstone wolf reintroduction triggering a trophic cascade that changed river courses; Iberian lynx recovery; describe minimum viable population theory and conservation triage; examine ethical debates in deciding which species to prioritise
- [Earth's Atmosphere & CO2](https://ai.page/c/earth-s-atmosphere-and-co2/index.md): Describe the composition of Earth's atmosphere (mainly nitrogen and oxygen, with small amounts of CO₂ and other gases), explain how human activity increases CO₂, and describe the impact on global climate
