1. Engineering, Technology, and Applications of Science

1. Simple Design Problems: Define a simple design problem reflecting a need or want that includes specified criteria for success and constraints on materials, time, or cost
2. Comparing Possible Solutions: Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints
3. Fair testing (age 8+): Plan and carry out fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved

2. Energy

1. How energy travels around: Observe and provide evidence that energy can be transferred from place to place by sound, light, heat, and electric currents
2. Natural resources: Obtain and combine information to describe that energy and fuels are derived from natural resources and that their uses affect the environment
3. Building an energy-converting device: Apply scientific ideas to design, test, and refine a device that converts energy from one form to another
4. Speed and energy: Use evidence to construct an explanation relating the speed of an object to the energy of that object
5. What happens when things collide: Ask questions and predict outcomes about the changes in energy that occur when objects collide

3. Waves: Waves and Information

1. Patterns & Codes for Information: Generate and compare multiple solutions that use patterns to transfer information, such as codes and signals
2. Waves & How They Move: Develop a model of waves to describe patterns in terms of amplitude and wavelength, and understand that waves can cause objects to move

4. Earth's Systems: Processes that Shape the Earth

1. Natural Disaster Solutions: Generate and compare multiple solutions to reduce the impacts of natural Earth processes on humans, such as earthquakes, floods, or volcanic eruptions
2. Finding patterns in data: Analyse and interpret data from maps to describe patterns of Earth's features, recognising that many features result from processes that occur over long periods
3. Erosion and weathering: Make observations and measurements to provide evidence of the effects of weathering or the rate of erosion by water, ice, wind, or vegetation
4. How fossils form: Identify evidence from patterns in rock formations and fossils in rock layers to support an explanation for changes in a landscape over time

5. Structure, Function, and Information Processing

1. Senses, Brain & Responses: Use a model to describe that animals receive information through their senses, process it in their brain, and respond in different ways
2. Structures for Survival: Construct an argument that plants and animals have internal and external structures that function to support survival, growth, behaviour, and reproduction
3. How We See Objects: Develop a model to describe that light reflecting from objects and entering the eye allows objects to be seen
