1. Links Among Engineering, Technology, Science, and Society

  1. Building an energy-converting device: Apply scientific ideas to design, test, and refine a device that converts energy from one form to another

2. Engineering Design

  1. Comparing Design Solutions: Analyse data from tests of two objects designed to solve the same problem to compare the strengths and weaknesses of each design
  2. 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

3. 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

4. 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. Reading Weather Maps: Read and interpret weather maps, data tables, and graphs — identifying symbols for sun, rain, wind, and temperature; spotting trends and patterns in weather data over weeks, months, or seasons; and using data to make simple predictions
  4. Cloud Types: Identify the three main cloud types — cumulus (fluffy, fair weather), stratus (flat layers, overcast or drizzle), and cirrus (thin wisps, high up) — and understand that clouds form when water vapour in the air cools and condenses into tiny droplets
  5. The Water Cycle: Understand the water cycle: the Sun heats water in oceans and lakes causing it to evaporate into water vapour, the vapour rises and cools to form clouds (condensation), and water falls back to Earth as rain, snow, or hail (precipitation) — then the cycle repeats

5. Earth's Place in the Universe

  1. Naming the Planets: Name the planets in our solar system in order from the Sun and use vocabulary for space — planet, star, sun, moon, satellite, orbit, solar system, galaxy, universe, asteroid, comet — applying these correctly when describing the structure of the solar system and objects we see in the sky

6. Biological Change: Unity and Diversity

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

8. From Molecules to Organisms: Structures and Processes

  1. Structures for Survival: Construct an argument that plants and animals have internal and external structures that function to support survival, growth, behaviour, and reproduction

9. Energy

  1. Magnetic Materials: Observe how magnets attract or repel each other and attract some materials and not others
  2. Speed and energy: Use evidence to construct an explanation relating the speed of an object to the energy of that object
  3. What happens when things collide: Ask questions and predict outcomes about the changes in energy that occur when objects collide

10. Motion and Stability: Forces and Interactions

  1. Magnetic Poles: Describe magnets as having two poles (north and south) and predict whether two magnets will attract or repel based on which poles face each other

11. Matter and Its Interactions

  1. Properties of materials: Compare and group different kinds of rocks based on their appearance and simple physical properties such as hardness, texture, and colour
  2. Heating & Cooling Changes: Observe and describe that some materials change state when heated or cooled, and measure the temperature at which changes occur in degrees Celsius
  3. Matter Is Made of Particles: Develop a model to describe that matter is made of particles too small to be seen, and that this explains properties of solids, liquids, and gases
