0 of 19 concepts ready to learn · Markdown, for your AI

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. Language Standards · Determine or clarify the meaning of unknown and multiple-meaning words and phrases based on grade 3 reading and content, choosing flexibly from a range of strategies.

1. Choosing the Right Material: Identify and compare the suitability of everyday materials for particular uses, explaining why specific materials are chosen for specific purposes

9. Writing Standards · Write narratives to develop real or imagined experiences or events using effective technique, descriptive details, and clear event sequences.

1. Drawing conclusions from evidence: Report on findings from enquiries using oral and written explanations, draw simple conclusions, make predictions, and suggest improvements

10. Writing Standards · Write opinion pieces, supporting a point of view with reasons.

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

11. Science

1. 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
2. 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
