Student lesson
- Electricity gives us light, heat, sound and movement.
- Appliances change electricity into other energy.
- Mains electricity is dangerous.
- Learners only use batteries for investigations.
Words to know
a form of energy that makes machines work
a machine that uses electricity
the electricity supply from sockets
something that could cause harm
1. Discover: The power cut
When the lights go out, Efua’s family lights a lantern. The fan stops, the fridge is silent, and the radio dies. “Without electricity we notice how much we use,” Efua says. Her father reminds her, “And we never touch sockets or wires. Mains electricity is dangerous.”
Think: What did you use today that needs electricity?
2. Understand: Electricity
Idea 1: What electricity does
Electricity makes lamps give light, heaters give heat, radios make sound and fans move. A machine that uses electricity is an appliance.
Idea 2: Where it comes from
Power stations, solar panels and batteries make electricity. Mains electricity comes through wires to sockets in buildings.
Idea 3: Staying safe
Mains is a serious hazard. Never touch sockets, plugs or wires, never use electricity near water and never put objects into sockets. In class we use only small batteries.
3. Worked examples
Example 1 (I show you): Sort
Lamp.
- Gives light.
- Uses electricity.
- Appliance.
Answer: A lamp changes electricity into light.
Example 2 (We do it together): Sort
Fan.
- Moves air.
- Movement.
- Appliance.
Answer: A fan changes electricity into movement.
Example 3 (You try): Safety
Wet hands and sockets.
Show the steps and answer
- Water conducts.
- Very dangerous.
- Never.
Answer: Never touch electricity with wet hands.
Did you know?
Lightning is a huge natural electric spark and can heat the air around it to five times hotter than the surface of the Sun.
Why this matters
Electricity improves our lives, but only if we respect it.
4. Explore: Electricity audit
List appliances in a typical home and say what energy each gives.
- List ten appliances.
- Say what each does.
- Sort by light, heat, sound or movement.
- Share safety rules.
Think about it: what did you notice?
What did you notice? Almost every room has electrical appliances.

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: “Electricity is safe to touch.” Mains is dangerous.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Explain electricity uses and safety.
- 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 learns electricity uses and safety. You do not need to be an expert to help.
- Name appliances together.
- Ask “Is it safe?”
- Keep wires out of reach.
- 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: name uses of electricity; sort appliances by what they do; explain why we must respect mains electricity; list basic electrical safety rules.
Prerequisite knowledge. Grade 3 physical ideas: forces, magnets, materials and measuring in fair tests.
Materials. Notebook, pencil. 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. Print appliance cards.
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). Switch off the lights and ask, “What stops working?”
Explanation (10 min). Teach electricity.
Guided activity (10 min). Learners sort.
Independent activity (10 min). Learners discuss safety.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. What energy? Is it safe?
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. “Electricity is safe to touch.” Mains is dangerous.
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 electricity uses and safety. 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.
