1. 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

2. Biological Evolution: Unity and Diversity

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)
2. 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

3. 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

4. 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

5. EARTH’S PLACE IN THE UNIVERSE

1. Fast & Slow Earth Changes: Understand that Earth's surface changes: some changes are quick (eruptions, earthquakes) and some are slow (wind, water wearing away rock)

6. ECOSYSTEMS: INTERACTIONS, ENERGY, AND DYNAMICS

1. Simple Food Chains: Describe how animals obtain their food from plants and other animals, using the idea of a simple food chain, and identify different sources of food
2. How Plant Parts Work: Identify and describe the functions of different parts of flowering plants: roots absorb water and nutrients, stems transport materials, leaves make food, flowers enable reproduction

7. MATTER AND ITS INTERACTIONS

1. Irreversible Changes: Explain that some changes result in the formation of new materials and are not usually reversible, such as burning, rusting, and reactions with acid
2. Choosing the Right Material: Identify and compare the suitability of everyday materials for particular uses, explaining why specific materials are chosen for specific purposes
3. Properties of materials: Compare and group different kinds of rocks based on their appearance and simple physical properties such as hardness, texture, and colour
