1. Engineering Design

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

2. Earth's Systems

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

3. Earth's Place in the Universe

1. 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. Biological Evolution: Unity and Diversity

1. How animals adapt to environments: Identify how animals and plants are adapted to suit their environment and understand that adaptation may lead to evolution over time

5. Ecosystems: Interactions, Energy, and Dynamics

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

6. Matter and its Interactions

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

7. Geography

1. Geography & Local Weather: Know that different places around the world have very different typical weather — tropical places are hot and wet all year, deserts are very dry, polar regions are freezing cold — and that geography (distance from the equator, altitude, nearness to the sea) affects local weather
