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

Goal: Nebraska academic standards: Science, Grade 2

## 1. Earth’s Systems: Processes That Shape the Earth · Gather, analyze, and communicate evidence of the processes that shape the earth.

- [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. Interdependent Relationships in Ecosystems · Gather, analyze, and communicate evidence of interdependent relationships in ecosystems.

- [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
- [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

## 3. Structure and Properties of Matter · Gather, analyze, and communicate evidence of the structure, properties, and interactions of matter.

- [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
- [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
