1. Nature of Science (K-8) · Science is not static. Science is constantly changing as we acquire more knowledge.

  1. Science Can Be Revised: Scientific knowledge is provisional — it is the best current explanation based on available evidence, and it can and should be revised when better evidence arrives

2. Nature of Science (K-8) · Science has been, and continues to be, advanced by individuals of various races, genders, ethnicities, languages, abilities, family backgrounds and incomes.

  1. Could there be another explanation?: For any result, ask: is there another explanation? — the first explanation that fits isn't always the right one, and good scientists actively look for alternatives

3. Nature of Science (K-8) · Science assumes the universe is a vast single system in which basic laws are consistent. Natural laws operate today as they did in the past and they will continue to do so in

  1. Asking scientific questions: Ask simple scientific questions and recognise that they can be answered in different ways including observation, testing, and research

4. Physical Science

  1. Naming types of energy: Name and use vocabulary for types of energy and energy transfer — kinetic energy, potential energy, heat energy, light energy, sound energy, electrical energy, chemical energy, stored energy, energy transfer, energy transformation — and describe energy changes in familiar situations using these terms
  2. Building an energy-converting device: Apply scientific ideas to design, test, and refine a device that converts energy from one form to another
  3. Speed and energy: Use evidence to construct an explanation relating the speed of an object to the energy of that object
  4. What happens when things collide: Ask questions and predict outcomes about the changes in energy that occur when objects collide
  5. 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
  6. Solids, Liquids & Gases: Compare and group materials as solids, liquids, or gases based on their observable properties and behaviour
  7. Classifying Materials: Plan and conduct an investigation to classify different kinds of materials by their observable properties
  8. Volume & Vibrations: Find patterns between the volume of a sound and the strength of the vibrations that produced it
  9. Measuring accurately: Make systematic and careful observations, take accurate measurements using standard units and equipment including thermometers and data loggers
  10. Conservation of Mass: Measure and provide evidence that the total weight of matter is conserved regardless of the type of change (heating, cooling, or mixing)
  11. Accurate Measurement: Take measurements with increasing accuracy and precision using a range of scientific equipment, taking repeat readings when appropriate
  12. 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

5. Life Science

  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
  2. 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
  3. 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
  4. 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
  5. 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
  6. 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. Offspring resemble parents: Observe that young plants and animals resemble their parents but are not identical, recognising inherited similarities and individual differences
  8. Seeds & Plant Growth: Observe and describe how seeds and bulbs grow into mature plants through stages of germination and growth
  9. Changing Environments: Recognise that environments can change and that this can sometimes pose dangers and challenges to living things
  10. Traits: inherited and environmental: Use evidence to support the explanation that traits can be influenced by the environment as well as inheritance

6. Earth and Space Science

  1. Preventing Erosion: Compare multiple solutions designed to slow or prevent wind or water from changing the shape of the land
  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
  3. Properties of materials: Compare and group different kinds of rocks based on their appearance and simple physical properties such as hardness, texture, and colour
  4. Rocks and soil: Recognise that soils are made from rocks and organic matter, and that different soils have different properties
  5. How fossils form: Identify evidence from patterns in rock formations and fossils in rock layers to support an explanation for changes in a landscape over time
