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's Systems: Processes that Shape the Earth

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. Interdependent Relationships in Ecosystems

1. Plants and animals in their habitats: 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
2. What Plants Need to Grow: Understand that plants need water, light, and a suitable temperature to grow and stay healthy

4. Structure and Properties of Matter

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