Part of: [South Carolina: Science](https://ai.page/roadmap/sc-sci.md)

Goal: South Carolina academic standards: Science, Grade 7

## 1. Ecosystems: Interactions, Energy, and Dynamics

- [Food Webs & Interdependence](https://ai.page/c/food-webs-and-interdependence/index.md): Construct and interpret food webs showing the interdependence of organisms in an ecosystem, explaining how a change in one population affects others
- [Biodiversity & Resilience](https://ai.page/c/biodiversity-and-resilience/index.md): Explain what biodiversity means, why high biodiversity makes ecosystems more resilient, and describe the ways human activity threatens biodiversity (habitat destruction, pollution, invasive species, climate change)
- [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

## 2. From Molecules to Organisms: Structures and Processes

- [Energy from Food & the Sun](https://ai.page/c/energy-from-food-and-the-sun/index.md): Use models to describe that energy in animals' food was once energy from the sun, transferred through plants or other organisms
- [Photosynthesis](https://ai.page/c/photosynthesis/index.md): Explain photosynthesis as the process by which plants use light energy to convert carbon dioxide and water into glucose and oxygen, and describe how mineral nutrients are absorbed through roots

## 3. Energy

- [Speed and energy](https://ai.page/c/speed-and-energy/index.md): Use evidence to construct an explanation relating the speed of an object to the energy of that object
- [Energy stores and transfers](https://ai.page/c/energy-stores-and-transfers/index.md): Identify the main energy stores (kinetic, gravitational potential, elastic potential, thermal, chemical, nuclear, electromagnetic) and the pathways by which energy is transferred between stores (mechanically, electrically, by heating, by radiation)

## 4. Matter and Its Interactions

- [Reactions That Release or Absorb Heat](https://ai.page/c/reactions-that-release-or-absorb-heat/index.md): Distinguish between exothermic reactions (release energy, temperature rises) and endothermic reactions (absorb energy, temperature falls), with everyday and industrial examples
- [Conservation of Mass](https://ai.page/c/conservation-of-mass/index.md): Measure and provide evidence that the total weight of matter is conserved regardless of the type of change (heating, cooling, or mixing)
- [Atoms, Elements & Compounds](https://ai.page/c/atoms-elements-and-compounds/index.md): Explain the differences between atoms, elements, and compounds; describe the simple Bohr model of the atom (nucleus with protons and neutrons, electrons in shells); and write and interpret chemical symbols and simple formulae
- [Pure Substances & Mixtures](https://ai.page/c/pure-substances-and-mixtures/index.md): Distinguish between pure substances and mixtures, identify formulations as useful mixtures with precise compositions, and use melting and boiling points to test for purity
