0 of 22 concepts ready to learn · Markdown, for your AI

1. Earth and Space Science

  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

2. Life Science

  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. 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
  4. 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
  5. Fossils as Evidence: Analyse and interpret data from fossils to provide evidence of organisms and environments that existed long ago
  6. Traits: inherited and environmental: Use evidence to support the explanation that traits can be influenced by the environment as well as inheritance
  7. Animal Groups & Survival: Construct an argument that some animals form groups that help members survive, such as herds, packs, or colonies
  8. 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. Physical 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. 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

4. EARTH AND HUMAN ACTIVITY

  1. 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

5. EARTH’S SYSTEMS

  1. Climate Zones: Understand that Earth has distinct climate zones — tropical (hot and wet near the equator), temperate (moderate, with four seasons), polar (freezing cold), arid/desert (very dry), and mountain (cold at high altitude) — and that each zone supports different ecosystems and ways of life
  2. Local weather patterns: Use and share observations of local weather conditions to describe patterns over time, recording temperature, rainfall, and other conditions

6. BIOLOGICAL EVOLUTION: UNITY AND DIVERSITY

  1. 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

7. HEREDITY: INHERITANCE AND VARIATION OF TRAITS

  1. Inheritance Vocabulary: Use vocabulary for variation and inheritance — inherited characteristic, acquired characteristic, variation, offspring, trait, species, breed, genetic, environment — and apply these when comparing organisms and explaining similarities and differences within and between species

8. MOTION AND STABILITY: FORCES AND INTERACTIONS

  1. Forces Vocabulary: Name and describe forces using precise vocabulary — force, push, pull, twist, stretch, squash, contact force, non-contact force, gravity, weight, friction, air resistance, upthrust — and distinguish between forces that require physical contact and forces that act at a distance
  2. Friction & Surfaces: Compare how things move on different surfaces, noticing that some surfaces create more friction than others
