Student lesson
- The heart pumps blood round the body.
- Arteries, veins and capillaries are vessels.
- Blood carries oxygen and nutrients.
- Pulse shows the heart rate.
Words to know
the muscle that pumps blood
a vessel taking blood away from the heart
a vessel bringing blood to the heart
a tiny vessel linking arteries and veins
1. Discover: The heartbeat
Esi places two fingers on her wrist and feels a gentle beat: her pulse. After walking up the school steps the beat is faster. “My heart is pumping more blood to my muscles,” she says.
Think: Why does the pulse speed up?
2. Understand: Circulation
Idea 1: The heart
The heart is a muscle with four chambers. It pumps blood to the lungs to pick up oxygen and then to the rest of the body.
Idea 2: Vessels
Arteries carry blood away from the heart. Veins bring it back. Capillaries are tiny tubes where oxygen and nutrients pass into cells.
Idea 3: Blood
Blood carries oxygen, nutrients and waste. Red cells carry oxygen, white cells fight germs and platelets help clot cuts. Resting pulse is about 70 to 100 beats a minute for adults and often higher for children.
3. Worked examples
Example 1 (I show you): Name
Away from heart.
- Artery.
- Out.
- Carry.
Answer: Artery.
Example 2 (We do it together): Name
Tiny vessel.
- Capillary.
- Exchange.
- Tiny.
Answer: Capillary.
Example 3 (You try): Explain
Pulse.
Show the steps and answer
- Heart pumps.
- Beat.
- Faster.
Answer: Pulse shows heartbeat.
Did you know?
The human heart beats around 100,000 times a day and pumps about 7,000 litres of blood.
Why this matters
A healthy circulatory system keeps every cell supplied.
4. Explore: Pulse check
Find your pulse at the wrist at rest, then after 30 seconds of gentle marching, and record both.
- Sit quietly one minute.
- Find pulse with two fingers.
- Count for 15 seconds.
- March gently and recount.
Think about it: what did you notice?
What did you notice? The pulse was faster after marching.
5. Practise

- An ___ carries blood away.
- A ___ brings blood back.

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: “Veins are red and arteries blue.” Colours are a diagram code.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Explain circulation.
- 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 about blood and the heart. You do not need to be an expert to help.
- Feel pulse together.
- Ask “Why faster?”
- Gentle 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: name the heart and blood vessels; describe blood’s journey; explain what blood carries; measure pulse.
Prerequisite knowledge. Grade 4 ideas: the skeleton, muscles, teeth, digestion basics, the heart and healthy habits.
Materials. Clock, 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. Practise pulse.
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). Feel a wrist pulse and ask, “What is this?”
Explanation (10 min). Teach circulation.
Guided activity (10 min). Learners test.
Independent activity (10 min). Learners explain.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. What pumps? What carries?
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. “Veins are red and arteries blue.” Colours are a diagram code.
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 circulation. 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.
