Part of: [Delaware: Science](https://ai.page/roadmap/de-sci.md)

Goal: Delaware academic standards: Science, Grade 2

## 1. Earth's Systems

- [Shapes of land and water](https://ai.page/c/shapes-of-land-and-water/index.md): Develop a model to represent the shapes and kinds of land (mountains, valleys, plains) and bodies of water (rivers, lakes, oceans) in an area
- [Where water is found on Earth](https://ai.page/c/where-water-is-found-on-earth/index.md): Identify where water is found on Earth and understand that water can exist as solid (ice) or liquid, recognising water in oceans, rivers, glaciers, and underground
- [Preventing Erosion](https://ai.page/c/preventing-erosion/index.md): Compare multiple solutions designed to slow or prevent wind or water from changing the shape of the land

## 2. Earth's Place in the Universe

- [Rapid earth changes](https://ai.page/c/rapid-earth-changes/index.md): Use information from several sources to provide evidence that Earth events can occur quickly (earthquakes, volcanic eruptions) or slowly (erosion, mountain building)

## 3. Biological Evolution: Unity and Diversity

- [How animals adapt to environments](https://ai.page/c/how-animals-adapt-to-environments/index.md): Identify how animals and plants are adapted to suit their environment and understand that adaptation may lead to evolution over time

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

- [Plants and animals in their habitats](https://ai.page/c/plants-and-animals-in-their-habitats/index.md): Use a model to represent the relationship between the needs of different plants and animals and the places they live, connecting organism needs to habitat features
- [What Plants Need to Grow](https://ai.page/c/what-plants-need-to-grow/index.md): Understand that plants need water, light, and a suitable temperature to grow and stay healthy

## 5. Matter and its Interactions

- [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
- [Taking Apart & Rebuilding](https://ai.page/c/taking-apart-and-rebuilding/index.md): Observe that an object made of a small set of pieces can be disassembled and made into a new object, understanding that the pieces still exist
- [Testing Materials for Uses](https://ai.page/c/testing-materials-for-uses/index.md): Give reasons, based on evidence from comparative and fair tests, for the particular uses of everyday materials including metals, wood, and plastic
- [Classifying Materials](https://ai.page/c/classifying-materials/index.md): Plan and conduct an investigation to classify different kinds of materials by their observable properties
