1. Earth’s Systems: Processes That Shape the Earth · Gather, analyze, and communicate evidence of the processes that shape the earth.

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)

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
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

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