1. Science

1. Shapes of land and water: Develop a model to represent the shapes and kinds of land (mountains, valleys, plains) and bodies of water (rivers, lakes, oceans) in an area
2. Preventing Erosion: Compare multiple solutions designed to slow or prevent wind or water from changing the shape of the land
3. Rapid earth changes: Use information from several sources to provide evidence that Earth events can occur quickly (earthquakes, volcanic eruptions) or slowly (erosion, mountain building)
4. Where water is found on Earth: 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
5. What Plants Need to Grow: Understand that plants need water, light, and a suitable temperature to grow and stay healthy
6. Pollination & Seed Dispersal: Understand the life cycle of flowering plants including pollination, seed formation, and seed dispersal
7. Habitats & Basic Needs: 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
8. Local Plants & Animals: Identify and name a variety of plants and animals in their habitats, including microhabitats such as under a log or in a pond
9. Classifying Materials: Plan and conduct an investigation to classify different kinds of materials by their observable properties
10. Choosing the Right Material: Identify and compare the suitability of everyday materials for particular uses, explaining why specific materials are chosen for specific purposes
11. Testing Materials for Uses: Give reasons, based on evidence from comparative and fair tests, for the particular uses of everyday materials including metals, wood, and plastic
12. Taking Apart & Rebuilding: 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
13. Heating & Cooling Changes: Observe and describe that some materials change state when heated or cooled, and measure the temperature at which changes occur in degrees Celsius
