Sample questions

A few real prompts from the game to help you choose an activity for your class.

  1. Match each body system to its job.

    • the respiratory system
    • the digestive system
    • the excretory system
    • the muscular system
    Read the explanation

    The body runs on several systems working together.

  2. Match each organ to how you care for it.

    • lungs
    • the stomach
    • kidneys
    • heart
    Read the explanation

    Cared for properly, an organ serves you far longer.

  3. Match each habit to the system it damages.

    • smoking
    • eating very salty food
    • eating at all hours
    • not exercising
    Read the explanation

    A risky habit strikes one system directly.

Game teaching guide

What children will practise

Know the body's systems, respiratory, digestive, excretory, muscular and circulatory, how to care for key organs, which habits damage each system, and warning signs that call for a doctor.

What's in the worksheet

4 matching rounds, 4 pairs each - System to job, e.g. respiratory brings in oxygen, excretory removes waste - Organ to care, e.g. kidneys with enough water and less salt, stomach with regular meals and chewing well - Habit to damaged system, e.g. very salty food with the excretory system, no exercise with the circulatory system - Organ to warning sign, e.g. heart with palpitations and tiring easily

How to use it in class

Use in the 'our bodies' unit; about 6 minutes. - Keep a picture of internal organs beside the game and have children point to lungs, heart, stomach and kidneys on themselves - Play in teams; for round 3, have teams explain why salty food concerns the excretory system - If round 1 goes badly, add actions, breathing in and out, rubbing the tummy, moving an arm - Play it linked to the class to record results in the mark book.

Common sticking points

- Round 3: Grade 3 children often think the excretory system means going to the toilet for a poo, so they do not link it with the kidneys; explain the kidneys filter waste into urine - Round 3: the circulatory system is not in round 1, so children may not know it and leave it to last - Round 2: regular exercise (the heart's care) also helps the lungs, so the two may be swapped - Round 4: kidneys with abnormal urine is usually fine if round 3 went well
