Goal: Base Nacional Comum Curricular (BNCC), Ensino Fundamental: Ciências (Science), 4º ano

## 1. Science

- [Heating & Cooling Changes](https://ai.page/c/heating-and-cooling-changes/index.md): Observe and describe that some materials change state when heated or cooled, and measure the temperature at which changes occur in degrees Celsius
- [Reversible Changes](https://ai.page/c/reversible-changes/index.md): Demonstrate that dissolving, mixing, and changes of state are reversible changes where no new materials are formed
- [Food Chains & Energy Transfer](https://ai.page/c/food-chains-and-energy-transfer/index.md): Construct and interpret food chains identifying producers, predators, and prey, and understand energy transfer between trophic levels
- [Matter Cycling in Ecosystems](https://ai.page/c/matter-cycling-in-ecosystems/index.md): Develop a model to describe the movement of matter among plants, animals, decomposers, and the environment in an ecosystem
