Student lesson
- Temperature is measured in degrees Celsius.
- Heat flows from hot to cold.
- Insulators slow heat loss.
- Most materials expand when heated.
Words to know
energy flowing because of a temperature difference
how hot or cold something is
a tool that measures temperature
material that slows heat transfer
1. Discover: The warm lunchbox
Selase wraps one jar of warm water in wool and leaves another bare. After 20 minutes the wool jar is 41 °C and the bare jar 33 °C. “Wool is a good insulator,” he says.
Think: Why wrap food?
2. Understand: Heat
Idea 1: Heat and temperature
Temperature says how hot something is, in °C, using a thermometer. Heat is energy that flows from a hotter place to a colder one.
Idea 2: Insulation
Insulation such as wool, foam or air gaps traps heat. It keeps drinks warm and homes cool.
Idea 3: Expansion
Most materials expand when heated and contract when cooled. Bridges have small gaps to allow for this.
3. Worked examples
Example 1 (I show you): Read
Thermometer.
- Eye level.
- Scale.
- Unit.
Answer: Read at eye level in °C.
Example 2 (We do it together): Choose
Warm drink.
- Wool.
- Foam.
- Insulator.
Answer: Wrap in wool.
Example 3 (You try): Explain
Gaps.
Show the steps and answer
- Expand.
- Bridge.
- Warm.
Answer: Allow for expansion.
Did you know?
The Eiffel Tower grows about 15 centimetres taller in hot summer weather because the iron expands.
Why this matters
Heat knowledge helps us cook, build and save energy.
4. Explore: Insulation test
Wrap identical jars of warm water in wool, foil, paper and nothing, and record temperature every five minutes.
- Fill jars with warm water.
- Wrap each.
- Measure temperature.
- Record every five minutes.
Think about it: what did you notice?
What did you notice? Wool kept the water warmest.

Mastery and remediation
| Objective | Bronze (Developing) | Silver (Proficient) | Gold (Advanced) |

Courseversity badge thresholds (overall quiz score): Gold = 90–100%; Silver = 80–89.9%; Bronze = 70–79.9%. A badge is never a full record of progress.
If a learner struggles
- Find the misconception: “Heat and temperature are the same.” Different.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Explain heat and temperature.
- Guided practice: work through one example together and let the learner try the next one.
- Reassess: use the quiz again or the worksheet.
- Move on when the learner shows Silver-level evidence independently.
For parents and guardians
In this lesson your child tests insulation. You do not need to be an expert to help.
- Compare warm cups.
- Ask “Which is warmer?”
- Warm water only.
- Ask “how do you know?” after each answer, and listen.
- Praise effort, not only right answers. Mistakes are how we learn.
- Ten to fifteen minutes a day is better than one long session.
Teacher package
1–5. Objectives, prerequisites, materials, preparation, duration
Lesson objectives. Learners will: distinguish heat and temperature; measure temperature; test insulators; explain expansion.
Prerequisite knowledge. Grade 4 ideas: light, sound, simple circuits, heat and temperature, and forces.
Materials. Jars, thermometer, wool, foil. Low-resource options: use chalk or charcoal on a board or wall, drawings in the sand, and objects from the classroom instead of printed materials.
Preparation. Warm water.
Suggested duration. 45–60 minutes. It can be split into two shorter sessions.
6–9. Teaching procedure, explanation notes, guided and independent activities
Introduction (5 min). Touch wool and metal and ask, “Which feels warmer?”
Explanation (10 min). Teach heat.
Guided activity (10 min). Learners test.
Independent activity (10 min). Learners graph.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. Hot or cold? Which insulates?
Teacher explanation notes. Start with real objects and safe, hands-on observation. Then talk about what was seen, then draw and write. Always say “how do you know?”. Keep to the safety notes, and use local, safe materials.
10–12. Differentiation, formative assessment, common misconceptions
Support. Use real objects and pictures, short sentences and a partner. Let learners point, show or draw instead of writing. Extension. Ask learners to find a new example at home and explain how they know.
Formative assessment. Listen to learners read and explain, ask “how do you know?”, and check the independent work.
Misconceptions. “Heat and temperature are the same.” Different.
13–15. Assessment questions, answer keys, marking scheme
Use the quiz, the 10-mark exam practice and the worksheet on this page. All answers and marking guides are in the answer sections above. Re-check every answer before use.
16–19. Remediation, enrichment, homework, teacher reflection
Remediation. Explain heat and temperature. Enrichment. Look for one new example near your home or school, draw it and explain it to someone. Homework. See above.
Teacher reflection. After teaching, record: which ideas learners understood; which misconceptions occurred; which activities worked; which learners need more practice; and what to improve next time.
