Every skill in the course, with its official code.
Unit 1 · 4 skills
Life Science: Interactions within Ecosystems
How Ecosystems Interact
Parts of an ecosystem interact
I can explain how the parts of an ecosystem interact and affect each other.
Official code: LS1
Food chains and food webs
I can illustrate food chains and food webs.
Official code: LS2
Energy transfer in an ecosystem
I can analyse how energy is transferred through an ecosystem.
Official code: LS2
Reducing human impact
I can propose actions to reduce human impact on an ecosystem.
Official code: LS3
The official wording · 4 outcomes
- LS1
- Explain how different parts of an ecosystem interact and affect each other.
- LS2
- Illustrate and analyse how food chains and food webs can be used
- LS2
- the transfer of energy in an ecosystem
- LS3
- Propose actions to reduce the impact of human activities on a specific ecosystem.
Key ideas
An ecosystem has living (biotic) and non-living (abiotic) parts.
Biotic factors include producers, consumers, and decomposers.
Abiotic factors include light, temperature, water, and soil.
The parts interact and depend on each other.
A food chain shows one path of who eats whom.
Watch out for
- Thinking non-living factors do not affect living things.
- Thinking each organism lives independently of the rest.
- Drawing arrows in the wrong direction (they point toward the eater).

Unit 2 · 3 skills
Physical Science: Mixtures and Solutions
Mixtures, Solutions, and Separating
Pure substances and mixtures
I can distinguish pure substances from mixtures using the particle theory.
Official code: PS1
Characteristics of solutions
I can describe the characteristics and uses of solutions.
Official code: PS2
Separating mixtures and solutions
I can design experiments to separate mixtures and consider their impact.
Official code: PS3
The official wording · 3 outcomes
- PS1
- Distinguish between pure substances and mixtures using the particle theory of matter.
- PS2
- Describe the characteristics and applications of solutions.
- PS3
- Design and conduct out experiments to explore methods of separating mixtures and solutions and extend the impact of those methods on society and the environment.
Key ideas
The particle theory says matter is made of tiny particles.
A pure substance has only one kind of particle.
A mixture has more than one kind of particle mixed together.
Mixtures can be heterogeneous (uneven) or homogeneous (even).
A solution is a homogeneous mixture that looks uniform.
Watch out for
- Thinking all clear liquids are pure substances.
- Thinking a mixture always looks obviously mixed.
- Thinking the solute disappears - it is still there, dissolved.

Unit 3 · 4 skills
Physical Science: Heat
Heat and How It Moves
The effect of heat on matter
I can describe how heat affects different forms of matter.
Official code: PS4
Conduction and convection
I can explain how heat transfers by conduction and convection.
Official code: PS5
Radiation
I can explain how heat transfers by radiation.
Official code: PS5
A heating or cooling device
I can design a device to solve a heating or cooling problem.
Official code: PS6
The official wording · 4 outcomes
- PS4
- Conduct experiments to describe the effect of heat on different forms of matter.
- PS5
- Explain how heat is transferred by conduction, convection and radiation in solids, liquids, and gasses.
- PS5
- Explain how heat is transferred by conduction, convection and radiation
- PS6
- Create a prototype of a device that will provide a solution to a practical heating or cooling problem.
Key ideas
Heating adds energy to matter.
Heat can change a solid to a liquid to a gas.
Most materials expand when heated.
Different materials respond to heat differently.
Conduction transfers heat through direct contact, mainly in solids.
Watch out for
- Thinking heat only makes things hotter, not change state.
- Thinking all materials respond to heat the same way.
- Thinking heat only moves by touching (conduction).

Unit 4 · 3 skills
Earth and Space Science: Earth's Crust
Rocks, the Crust, and Soil
Rocks and minerals
I can identify rocks and minerals and how they relate.
Official code: ESS1
Gradual and sudden changes to the crust
I can explain gradual and sudden changes to the Earth's crust.
Official code: ESS2
Soil formation and degradation
I can investigate how soil forms and what causes it to degrade.
Official code: ESS3
The official wording · 3 outcomes
- ESS1
- Identify the characteristics and relationships among rocks and minerals.
- ESS2
- Explain how the Earth’s crust undergoes gradual and sudden changes over time.
- ESS3
- Investigate the characteristics of soil and conditions that affect its formation and degradation.
Key ideas
Minerals are natural solids with their own properties.
Rocks are made of one or more minerals.
Rocks are classified as igneous, sedimentary, or metamorphic.
Properties like colour, hardness, and streak help identify minerals.
The crust changes over time.
Watch out for
- Thinking rocks and minerals are the same thing.
- Thinking colour alone identifies a mineral.
- Thinking the crust only changes slowly.
