1. Space Systems: Stars and the Solar System

1. Shadows: Represent data in graphical displays to reveal patterns of daily changes in shadow length and direction, day and night cycles, and seasonal star patterns
2. Star Brightness & Distance: Support an argument that the apparent brightness of the sun and stars is due to their relative distances from Earth, understanding the sun is a relatively close star
3. Gravity Pulls Things Down: Understand gravity as a force that pulls objects towards the centre of the Earth, that 'down' means towards Earth’s centre regardless of where you stand on the sphere, and that gravity keeps the Moon orbiting Earth and planets orbiting the Sun

2. Earth's Systems

1. Communities Protecting Resources: Obtain and combine information about ways individual communities use science ideas to protect the Earth's resources and environment
2. Salt Water vs Fresh Water: Describe and graph the amounts of salt water and fresh water in various reservoirs to provide evidence about the distribution of water on Earth
3. Earth's atmosphere: Develop a model to describe ways the geosphere, biosphere, hydrosphere, and atmosphere interact as connected Earth systems

3. Matter and Energy in Organisms and Ecosystems

1. Matter Cycling in Ecosystems: Develop a model to describe the movement of matter among plants, animals, decomposers, and the environment in an ecosystem
2. Plants Grow from Air & Water: Support an argument that plants get the materials they need for growth chiefly from air and water, not from the soil
3. Energy from Food & the Sun: Use models to describe that energy in animals' food was once energy from the sun, transferred through plants or other organisms

4. Structure and Properties of Matter

1. Pure Substances & Mixtures: Distinguish between pure substances and mixtures, identify formulations as useful mixtures with precise compositions, and use melting and boiling points to test for purity
2. Classifying Materials: Plan and conduct an investigation to classify different kinds of materials by their observable properties
3. Conservation of Mass: Measure and provide evidence that the total weight of matter is conserved regardless of the type of change (heating, cooling, or mixing)
4. Matter Is Made of Particles: Develop a model to describe that matter is made of particles too small to be seen, and that this explains properties of solids, liquids, and gases
