1. Earth and Space Sciences

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

2. Physical Science

1. 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
2. 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
3. Comparing Design Solutions: Analyse data from tests of two objects designed to solve the same problem to compare the strengths and weaknesses of each design
4. Classifying Materials: Plan and conduct an investigation to classify different kinds of materials by their observable properties

3. Life Science

1. 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
2. Pollination & Seed Dispersal: Understand the life cycle of flowering plants including pollination, seed formation, and seed dispersal
3. What Plants Need to Grow: Understand that plants need water, light, and a suitable temperature to grow and stay healthy
