1. Earth's Systems

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
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
Preventing Erosion: Compare multiple solutions designed to slow or prevent wind or water from changing the shape of the land

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)

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

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