Student lesson
- Mains is dangerous and can kill.
- Water and electricity do not mix.
- Fuses and breakers protect circuits.
- Stay away from power lines.
Words to know
the high-voltage supply to buildings
a safety part that melts if current is too high
a switch that trips if current is too high
a safety wire that carries fault current away
1. Discover: The safety poster
Class 6 designs a poster for younger children: “Never touch sockets. Never use electricity with wet hands. Stay away from fallen wires. Tell an adult at once.” The teacher adds: “Fuses and circuit breakers protect homes too.”
Think: Which rule would you tell a younger child first?
2. Understand: Staying safe
Idea 1: Dangers
Mains electricity is high voltage and can cause serious injury or death. Never touch sockets, plugs or bare wires, never use electricity near water, and never overload sockets.
Idea 2: Protection
A fuse melts if current is too high and cuts off the circuit. A circuit breaker does the same job and can be reset. An earth wire carries fault current safely away.
Idea 3: Outdoors
Stay at least 10 metres from fallen power lines, do not fly kites near them, never climb pylons and call the emergency number. Do not touch a person in contact with electricity; switch off the power if safe, or call for help.
3. Worked examples
Example 1 (I show you): List
Rules.
- No sockets.
- No water.
- Tell an adult.
Answer: Safety rules.
Example 2 (We do it together): Explain
Fuse.
- Melts.
- Cuts off.
- Protects.
Answer: Safety part.
Example 3 (You try): Plan
Emergency.
Show the steps and answer
- Do not touch.
- Call help.
- Switch off.
Answer: Safe response.
Did you know?
Even a current of about 0.1 amps through the body can be fatal, which is why mains is so dangerous.
Why this matters
Safe habits prevent accidents and fires.
4. Explore: Safety poster
Design a poster or short play that teaches younger children four electrical safety rules and one emergency step.
- List the rules.
- Plan the design.
- Make the poster.
- Present it.
Think about it: what did you notice?
What did you notice? Simple rules were the easiest to remember.

If a learner struggles
- Find the misconception: “Low current is always safe.” Mains is lethal.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: State electrical safety rules.
- 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 electrical safety rules. You do not need to be an expert to help.
- Check sockets with your child.
- Ask “What is unsafe?”
- Model safe habits.
- 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: state safety rules; explain dangers; explain fuses; respond to emergencies.
Prerequisite knowledge. Grade 5 ideas: simple circuits, conductors and insulators, and magnets.
Materials. Poster paper, markers. 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. Prepare posters.
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). Show a picture of an overloaded socket and ask, “What is unsafe?”
Explanation (10 min). Teach electrical safety.
Guided activity (10 min). Learners design.
Independent activity (10 min). Learners present.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. What is the danger? How do we stay 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. “Low current is always safe.” Mains is lethal.
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. State electrical safety rules. 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.
