1. Earth and Human Activity

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. Earth's Systems

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

3. Biological Evolution: Unity and Diversity

1. 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
2. How animals adapt to environments: Identify how animals and plants are adapted to suit their environment and understand that adaptation may lead to evolution over time
3. Fossils as Evidence: Analyse and interpret data from fossils to provide evidence of organisms and environments that existed long ago

4. Heredity: Inheritance and Variation of 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. Traits: inherited and environmental: Use evidence to support the explanation that traits can be influenced by the environment as well as inheritance

5. Ecosystems: Interactions, Energy, and Dynamics

1. Animal Groups & Survival: Construct an argument that some animals form groups that help members survive, such as herds, packs, or colonies

6. From Molecules to Organisms: Structures and Processes

1. 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

7. Motion and Stability: Forces and Interactions

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. 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)
3. 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
4. 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

8. Individual and Collective Responses to Environmental Change: Environmentally literate students construct and apply understanding of individual, collective, and societal responses to human-induced envi

1. Changing Environments: Recognise that environments can change and that this can sometimes pose dangers and challenges to living things

9. Environmental Impact of Human Activity: Environmentally literate students construct and apply understanding of the environmental impact of human activities on Earth’s systems and resources.

1. Human impact on environments: Use vocabulary for human impact on the environment — pollution, habitat destruction, deforestation, biodiversity, conservation, renewable energy, non-renewable energy, fossil fuel, carbon footprint, sustainability, endangered, extinct — and apply these when discussing environmental issues and human choices

10. Human Dependence on Earth Systems and Natural Resources: Environmentally literate students construct and apply understanding of how Earth’s systems and natural resources support human existence.

1. 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
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
