Key ideas
Concentration can be given in g/L, percentage, ppm, or mol/L (molar concentration = moles of solute / litres of solution).
The pH scale runs from acidic (low) through neutral (7) to alkaline (high); each step is a tenfold change.
Rapid combustion releases heat and light; it needs fuel, oxygen, and heat (the fire triangle).
A covalent bond results from atoms sharing electrons.
Energy is conserved: it is transformed, not created or destroyed.
Watch out for
- Thinking ppm and percentage are interchangeable units.
- Thinking a strong acid is the same as a concentrated acid.
- Thinking combustion can occur without oxygen.

The official wording · 3 outcomes
- 2.1
- Describes a given population
- 2.2
- Defines a community as a group of populations that interact
- 2.3
- Represents the photosynthesis reaction in a balanced equation
Key ideas
A population is described by density, distribution, and biological cycles.
Photosynthesis: carbon dioxide + water, using light, yields glucose + oxygen.
Biotic and abiotic factors and resource availability affect natality, mortality, immigration, and emigration.
Respiration reverses it: glucose + oxygen yields carbon dioxide + water + energy.
This also covers: describes the influence of biotic or abiotic factors on the biological cycles of a population; explains how the availability of resources affects reproduction and survival.
Watch out for
- Thinking only predators limit a population, not climate.
- Thinking plants only photosynthesize and never respire.
- Thinking density equals total number.

- Describes the geographical and climatic factors that affect the distribution of biomes
- 3.9
- Describes technologies used to produce electricity using the energy resources in the lithosphere, hydrosphere and atmosphere
Key ideas
Ore is rock rich enough in a mineral to be worth extracting; a mineral is the pure substance itself.
The carbon cycle moves carbon through photosynthesis, decomposition, dissolution, and fossil-fuel combustion.
A catchment area is the land that drains into a waterway.
The greenhouse effect traps outgoing heat, keeping Earth warm enough for life.
Latitude, humidity, temperature, and salinity determine where biomes occur.
Watch out for
- Thinking any rock containing a metal is ore.
- Thinking carbon is created or destroyed rather than cycled.
- Thinking a catchment area is only the river itself.

Skill 4.5
The official wording · 5 outcomes
- 4.1
- Describes the characteristics of the links in a technical object
- 4.2
- Explains the choice of a motion transmission system in a technical object
- 4.3
- Defines power supply as the ability to generate electrical current
- 4.4
- Describes the role of a protective device in a circuit
- 4.5
- Explains the choice of a material based on its properties
Key ideas
Links can be direct or indirect, rigid or flexible, removable or permanent, partial or complete.
A motion transmission system is chosen for its speed, torque, and reliability (a gear assembly to avoid slipping).
Power supply is the ability to generate current (battery, solar cell, alternator, thermocouple, piezoelectric).
Objects face constraints (tension, compression, torsion, deflection, shearing); a material is chosen so its properties resist them.
Good design chooses characteristics to fit the object's function and justifies the assembly solution.
Watch out for
- Thinking a permanent link is always better than a removable one.
- Thinking any motion system works equally well for any object.
- Thinking all metals conduct equally regardless of dimensions.
