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

Goal: South Dakota academic standards: Science, Grade 2

## 1. Earth and Space Science

- [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
- [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)

## 2. Life Science

- [Habitats & Basic Needs](https://ai.page/c/habitats-and-basic-needs/index.md): Identify that most living things live in habitats to which they are suited and describe how habitats provide for basic needs and how organisms depend on each other
- [Pollination & Seed Dispersal](https://ai.page/c/pollination-and-seed-dispersal/index.md): Understand the life cycle of flowering plants including pollination, seed formation, and seed dispersal
- [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

## 3. Physical 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
- [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
- [Comparing Design Solutions](https://ai.page/c/comparing-design-solutions/index.md): Analyse data from tests of two objects designed to solve the same problem to compare the strengths and weaknesses of each design
- [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
