The Building's Senses

1. What your child learns and why

Your child discovers that the sensors in buildings are like senses: the camera “sees”, the intercom microphone “hears”, the smoke alarm “smells”, the heat alarm “feels warm”, and the magnetic door contact “feels touch” — whether the door is closed. The aim is curiosity and a sense of order, not worry: a building keeps people safe by noticing and telling them. The lesson deliberately does not talk about burglars or fires.

2. Three questions for dinner

• “Which senses of the building did you see today — at home or at school?”
• “If a building has a nose, where is it? Why there?” (On the ceiling — smoke rises.)
• “And which sense do you use first when you walk into a new room?”

3. 15 minutes together, no screen — the sense hunt

1. Draw a simple map of your home or school: rooms are squares, doors are gaps.
2. Walk around together. Your child puts a sign for each “sense”: 👁️ camera · 👂 intercom · 👃 smoke alarm · 🖐️ heat alarm · ☝️ magnet on the door. Mark the green “exit” signs too.
3. Ask: “Is there a room without any sense? What would you put there?”

4. What success looks like

• Your child names at least three sensors and says which sense each one is like.
• The map has at least three signs and at least one green “exit” sign.

5. Common difficulties

• Mixes up a camera and a motion sensor → “The camera has a glass eye — a lens. A motion sensor usually has a milky white window.”
• Wants to press the “test” button → “An adult presses it. You watch and listen.”

Say: “You are an inspector — you look and write it down.” Avoid stories about burglars and fires, and comparisons with other children.

6. Safety

Looking only: do not touch the sensors and do not climb on chairs towards the ceiling. An adult presses the “test” button of a smoke alarm — the UK Home Office advises doing this at least once a month. Some children are not woken by the sound of an alarm, so the adults at home agree who wakes the children.

7. Where to go next

Next lesson: DB-PZ-02 “I Sense, I Think, I Signal” — what happens to a sensor's signal. Previous: DB-IS-01 “What Is a Sensor?”.

You don't need to know the answer. Say: “Let's find out together.”
