1. Grade 3

1. Drawing conclusions from evidence (age 9+): Report and present findings including conclusions, causal relationships, explanations, and a degree of trust in results using oral and written forms
2. 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
3. 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
4. Drawing conclusions from evidence: Report on findings from enquiries using oral and written explanations, draw simple conclusions, make predictions, and suggest improvements
5. 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
6. 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
7. Seasonal changes (age 8+): Represent data in tables and graphical displays to describe typical weather conditions expected during a particular season
8. Weather vs climate: Obtain and combine information to describe climates in different regions of the world, distinguishing between weather and climate
9. Weather Forecasting: Know that meteorologists are scientists who study and forecast the weather using satellites, radar, weather balloons, and computer models, and that weather forecasts help people plan their activities and prepare for dangerous weather
10. 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
11. Changing Environments: Recognise that environments can change and that this can sometimes pose dangers and challenges to living things
12. 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
13. 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
14. 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
15. Structures for Survival: Construct an argument that plants and animals have internal and external structures that function to support survival, growth, behaviour, and reproduction
16. Traits: inherited and environmental: Use evidence to support the explanation that traits can be influenced by the environment as well as inheritance
17. Classifying Materials: Plan and conduct an investigation to classify different kinds of materials by their observable properties
18. Offspring resemble parents: Observe that young plants and animals resemble their parents but are not identical, recognising inherited similarities and individual differences
19. Animal Groups & Survival: Construct an argument that some animals form groups that help members survive, such as herds, packs, or colonies
20. 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
21. 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)
22. 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
23. Force & Motion Vocabulary: Use technical vocabulary for force and motion — balanced forces, unbalanced forces, resultant force, acceleration, deceleration, speed, moment, lever, fulcrum, mechanical advantage — and apply these when explaining and predicting how forces affect the motion and position of objects
24. 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
