Goal: Colorado academic standards: Science, Grade 2

## 1. Earth and Space Science · Wind and water can change the shape of the land; models can show the shape and these changes to the land.

- [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
- [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 and Space Science · Some events on Earth occur quickly; others can occur very slowly.

- [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. Life Science · A range of different organisms lives in different places.

- [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

## 4. Life Science · Plants depend on water and light to grow and on animals for pollination or to move their seeds around.

- [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
- [What Plants Need to Thrive](https://ai.page/c/what-plants-need-to-thrive/index.md): Explore and compare the requirements of plants for life and growth: air, light, water, nutrients from soil, and room to grow

## 5. Physical Science · Matter exists as different substances that have observable different properties.

- [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
- [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
- [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
