1. Technology and Engineering

Designing for Weather Hazards: Make a claim about the merit of a design solution that reduces the impacts of a weather-related hazard such as flooding, wind damage, or extreme temperatures
Properties of materials: Compare and group different kinds of rocks based on their appearance and simple physical properties such as hardness, texture, and colour
Building an energy-converting device: Apply scientific ideas to design, test, and refine a device that converts energy from one form to another
Natural resources: Obtain and combine information to describe that energy and fuels are derived from natural resources and that their uses affect the environment
Comparing Design Solutions: Analyse data from tests of two objects designed to solve the same problem to compare the strengths and weaknesses of each design
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
Material Properties Vocabulary: Use technical vocabulary to describe and compare material properties — conductor, insulator, thermal, electrical, transparent, opaque, translucent, soluble, insoluble, magnetic, flexible, rigid, density — and apply these terms precisely when selecting and justifying materials for particular purposes

Communities Protecting Resources: Obtain and combine information about ways individual communities use science ideas to protect the Earth's resources and environment
Changing Environments: Recognise that environments can change and that this can sometimes pose dangers and challenges to living things

Contact & Non-Contact Forces: Notice that some forces need contact between two objects (contact forces) while magnetic forces can act at a distance (non-contact forces)
Balanced & Unbalanced Forces: Plan and conduct an investigation to provide evidence of the effects of balanced and unbalanced forces on the motion of an object
Predicting Motion Patterns: Make observations and measurements of an object's motion to provide evidence that a pattern can be used to predict future motion

Structures for Survival: Construct an argument that plants and animals have internal and external structures that function to support survival, growth, behaviour, and reproduction
Inherited characteristics: Analyse and interpret data to provide evidence that plants and animals have traits inherited from parents and that variation of these traits exists in a group of similar organisms
Variation & Survival Advantage: Use evidence to explain how variations in characteristics among individuals of the same species may provide advantages in surviving, finding mates, and reproducing
Fossils as Evidence: Analyse and interpret data from fossils to provide evidence of organisms and environments that existed long ago
Animal Groups & Survival: Construct an argument that some animals form groups that help members survive, such as herds, packs, or colonies
Traits: inherited and environmental: Use evidence to support the explanation that traits can be influenced by the environment as well as inheritance
Life Cycles of Organisms: Develop models to describe that organisms have unique and diverse life cycles but all share the common stages of birth, growth, reproduction, and death

Seasonal changes (age 8+): Represent data in tables and graphical displays to describe typical weather conditions expected during a particular season
Weather vs climate: Obtain and combine information to describe climates in different regions of the world, distinguishing between weather and climate

Communication with Light & Sound: Design and build a device that uses light or sound to solve the problem of communicating over a distance
