1. Engineering, Technology, and Applications of Science

1. Modelling with Sketches: Develop a simple sketch, drawing, or physical model to illustrate how the shape of an object helps it function as needed to solve a given problem
2. 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
3. Simple tests and experiments: Perform simple tests and use observations and ideas to suggest answers to questions

2. Earth and Space 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. 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
3. Preventing Erosion: Compare multiple solutions designed to slow or prevent wind or water from changing the shape of the land
4. 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)

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

4. 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. Classifying Materials: Plan and conduct an investigation to classify different kinds of materials by their observable properties
