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. Inheritance and Variation of Traits: Life Cycles and Traits

1. 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
2. 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
3. Traits: inherited and environmental: Use evidence to support the explanation that traits can be influenced by the environment as well as inheritance
4. 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

3. Forces and Interactions

1. 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)
2. 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
3. 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

4. Interdependent Relationships in Ecosystems

1. Changing Environments: Recognise that environments can change and that this can sometimes pose dangers and challenges to living things
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. Fossils as Evidence: Analyse and interpret data from fossils to provide evidence of organisms and environments that existed long ago
4. Animal Groups & Survival: Construct an argument that some animals form groups that help members survive, such as herds, packs, or colonies

5. Weather and Climate

1. 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
2. Seasonal changes (age 8+): Represent data in tables and graphical displays to describe typical weather conditions expected during a particular season
3. Weather vs climate: Obtain and combine information to describe climates in different regions of the world, distinguishing between weather and climate
