3. Prerequisite ladder
- Classification readiness: matter → pure substance → mixture → element
- Particle readiness: atom → ion → molecule → compound
- Energy-form readiness: energy → energy transfer → energy transformation → system
- Thermal readiness: thermal energy → heat → temperature → waste energy

- Energy-process readiness: photosynthesis → glucose → oxygen → cellular respiration
- Solar readiness: solar radiation → albedo → radiation → energy balance
- Transfer readiness: conduction → convection → radiation → wind
4. Mini-lesson explanation
- Concept launch linked to the session KCO targets.
- Worked model delivered with explicit think-aloud reasoning.
- Error analysis using this unit's common misconceptions.
Teacher explanation prompts:
- Ask learners to tally atoms before and after to justify conservation.
- Have learners draw the input, useful output, and waste for each device.
- Ask learners to trace one carbon atom through photosynthesis and respiration.
- Have learners label incoming, reflected, and outgoing energy on one diagram.
5. Worked examples
Worked example: Conservation of mass
Problem: 10 g of A reacts fully with 15 g of B. Find the product mass.
- Mass is conserved
- reactant total = 10 + 15
- product mass = same total
Answer: 25 g
Worked example: Read a formula
Problem: What does H2O tell you?
- Subscripts give atom counts
- 2 hydrogen atoms, 1 oxygen atom
Answer: water: 2 H and 1 O
Worked example: Efficiency from energy
Problem: A device outputs 125 J of useful energy from 500 J input. Find efficiency.
- efficiency = useful/input x 100
- = 125/500 x 100
Answer: 25%
Worked example: Efficiency of a motor
Problem: A motor gives 300 J useful work from 1200 J input.
- 300/1200 x 100
Answer: 25%
Worked example: Diffusion direction
Problem: Which way do particles move in diffusion?
- from high concentration
- to low concentration
- no energy required
Answer: high to low concentration
Worked example: Photosynthesis equation
Problem: Write the word/symbol equation for photosynthesis.
- reactants: carbon dioxide + water + light
- products: glucose + oxygen
Answer: 6CO2 + 6H2O + light -> C6H12O6 + 6O2
Worked example: Weather vs climate
Problem: Explain the difference between weather and climate.
- weather = short-term conditions
- climate = long-term average of weather
Answer: weather is short-term; climate is long-term average
Worked example: Convection drives wind
Problem: How does convection produce wind?
- uneven heating warms some air
- warm air rises, cool air sinks
- this circulation is wind
Answer: circulation from rising/sinking air
6. Guided practice
| Prompt | Answer |
|---|---|
| Give an example of a pure substance. | distilled water (or an element such as oxygen) |
| What does the formula NaCl tell you? | one sodium atom and one chlorine atom |
| List two pieces of evidence of a chemical change. | e.g., colour change and gas produced |
| Define efficiency. | the percentage of input energy that becomes useful output |
| A flashlight converts chemical energy mainly into what? | light (and some thermal) energy |
| How do heat and temperature differ? | temperature is average kinetic energy; heat is energy transfer |
| What controls what enters and leaves a cell? | the cell membrane |
| Which gas is released by photosynthesis? | oxygen |
| Where does cellular respiration mainly occur? | the mitochondria |
| What is Earth's main energy source? | the Sun (solar radiation) |
| Why is the equator warmer than the poles? | sunlight strikes it more directly |
| What does albedo measure? | the fraction of solar energy a surface reflects |
7. Misconception contrast
| Misconception | Correct concept |
|---|---|
| Mass disappears during a reaction. | Mass is conserved; it is only rearranged into products. |
| An atom and an ion are the same. | An ion is a charged atom that gained or lost electrons. |
| Heat and temperature are the same. | Temperature is average particle energy; heat is transferred energy. |
| Lost energy is destroyed. | Energy is transformed into waste forms, not destroyed. |
| Plants only photosynthesize and do not respire. | Plants do both: they make glucose and also respire to release its energy. |
| Diffusion requires energy input. | Diffusion is passive; it needs no energy input. |
| Weather and climate are the same. | Weather is short-term; climate is the long-term average. |
| One hot day proves the climate is warming. | Climate claims need long-term trends, not a single event. |
