Assemble a simple safety plan for a classroom or a room: where the smoke alarm goes, the exit sign, the route out, the meeting point outside, the evacuation scheme on the wall
Give the group roles (leader, last one who closes the door, counter at the meeting point) and explain why each matters
Explain the plan to others and make a version for someone else (younger class, family)
(ages 11–13) Check that the route works for everyone, e.g. a classmate who uses a wheelchair
KEY CONCEPTS
a plan joins everything from lessons 1–7: senses (sensors), the brain and the signal, the way out, and people with roles
smoke alarm on the ceiling, near the middle; heat alarm in the kitchen (London Fire Brigade)
plan a route, keep exits clear, think of a second route; get out, stay out, adults call 112 (UK Home Office; European Commission)
schools practise evacuation at least twice a year (Ordinance 8121з-647, art. 11)
the alarm push-button near the exit is for adults; children follow the teacher
STRUCTURE
goal → 1 Remember (3 questions from lessons 1, 4 and 7) → 2 Story (invented: a class designs its own plan before a drill) → 3 Worked example (a finished plan for a small library room: 5 places + 3 roles) → 4 Try it (Predict: what goes on the ceiling? → Run: assemble the classroom plan with 6 places, the plan is checked with kind hints → Change: give roles and print/see “Our plan”) + extra box for ages 11–13 (a route for everyone) → 5 Unplugged (present the plan to the class; walk the route slowly) → 6 Make your own (explain to someone else + make a plan card for someone: a younger class or the family) → 7 What I learned (3-question check + skill badge, no points) → 8 I have a question (form: the child writes ≤280 chars, the parent enters an e-mail and consents; double opt-in; plus "Was it useful?" / "We did the lesson" buttons — aggregate counts only)
ANSWERS
predict: the smoke alarm goes on the ceiling (smoke rises)
plan: ceiling → smoke alarm; above the door → green exit sign; wall by the door → evacuation scheme; corridor → clear route to the stairs; yard → meeting point; near the exit (for adults) → alarm push-button
roles: leader (goes first, calm pace), last one (closes the door behind the group), counter (counts at the meeting point with the teacher)
check: q1 c (the meeting point outside) · q2 a (closes the door behind the group) · q3 b (walk calmly, follow the teacher)
SAFETY
no experiments with fire or smoke; nobody touches real alarms, push-buttons or extinguishers; walking the route at school only with the teacher
the plan is a learning plan, not an official school plan; the official plan is the school's
no personal data: roles are chosen, not named; nothing stored; works offline

Project: The Smart Classroom
You already know the building's senses, the brain that gives a signal, the way out and the centre that never sleeps. Today you put everything into one plan — for your classroom or your room. You are the engineer.
⏱ 10–15 minCreatorThe Guardians · 8grades 1–7 · two levels
You will be able to assemble a safety plan for your classroom — alarm, exit, route, meeting point and roles — and explain it to others.
For the parent: a one-page guide — how to assess the project without a grade or label.

01Remember
Think about each question, then open the answer.
Which “sense” of the building notices smoke, and where is it?
The smoke alarm. It is on the ceiling, because smoke rises. (Lesson 1)
What are the three words of the escape plan?
Get out · stay out · an adult calls 112. (Lesson 4)
What does the operator in the centre that never sleeps do?
Receives the signals, checks them and decides what is urgent. (Lesson 7)
02Story
This story is made up.
Nia's class will have an evacuation drill. The teacher says: “This time you will make the plan.”
Bobby draws the classroom: the desks, the board, the door. “And where is the room's nose?” he asks.
“On the ceiling!” Nia laughs and draws a small white circle.
Then the children find the green sign above the door and the way along the corridor to the stairs. Outside they choose a meeting point — the big tree in the yard.
“We need roles too,” says the teacher. “Who will go first? Who will close the door? Who will count?”
On the day of the drill everything goes calmly and quickly. Nia is the leader. She walks with confidence, because the plan is theirs.
03Worked example
Here is a finished plan for a small reading room. It has five places and three roles:
Place
What is there
Why
The ceiling
Smoke alarm
smoke rises
Above the door
Green “Exit” sign
shows the way out
The wall by the door
Evacuation scheme
a drawing of the floor with the way to the exit
The corridor
A clear way to the stairs
nothing in the way
The yard
Meeting point
everyone gathers there and is counted
The roles: 🚶 leader — goes first, calmly · 🚪 last one — closes the door behind the group · 🔢 counter — counts with the teacher at the meeting point.
The plan says one more important thing: there is a second way if the first one is closed — for example another door or another staircase.
04Try it now
1 · Predict
What do we put on the classroom ceiling? Choose before you check.
2 · Run: assemble the classroom plan
This is a game. For each place, choose what goes there. Then press “Check the plan”. There is no wrong ending — only hints.
3 · Change: roles and “Our plan”
A plan comes alive when people know what to do. Choose the roles your group will have.
For older children · ages 11–13A good plan works for everyone. Imagine a classmate who uses a wheelchair. Your way out goes down stairs. What will you change? Hint: is there another exit on the same floor? Who will be with them? Write your solution into the plan.
05No screen: present the plan
You need: a big sheet of paper, felt-tip pens and the teacher or a parent with you.
Draw the plan of the classroom or room: ceiling, door, scheme, corridor, meeting point. Use the signs from lesson 1.
Share out the roles. Everyone can choose — or just watch this time.
Present the plan to the others: each person says one sentence about their part.
With the teacher, walk the route slowly, without hurrying. Count how many doors there are to the stairs.
For older children · ages 11–13Ask the teacher where the evacuation scheme for your floor is. Compare it with your plan. What did you guess right? What will you add?
✋
Calmly, with the teacher
We walk, we do not run. We do not touch real alarms, alarm buttons or fire extinguishers — they are for adults. We walk the route only with the teacher.
06Make your own
You are a creator now. Do two things:
Explain to someone. Tell the plan to someone who was not in the lesson — a younger brother or sister, a grandparent, a friend. Can you say it in five sentences?
Make it for someone. Make a plan card for a younger class or for your family: three drawings — the alarm, the way out, the meeting point.
Ask the person: “What was not clear?” and improve the card.
For older children · ages 11–13Make the plan as a one-page poster: map, roles, second way and how the route works for everyone. Present it to the class and collect three questions from classmates.
07What I learned
A plan brings everything together: the building's senses, the way out, the meeting point and the roles.
A good plan has a second way and works for everyone.
A plan is strong when everyone knows their part and can explain it.
In a group everyone has a role. Which role do you choose most often — leader, helper or counter?
Check yourself
1. Where does everyone gather after getting out?
2. What does the “last one” in the group do?
3. How do we walk the route in an evacuation drill?

Skill badge: “I make a plan for everyone” It is yours when you have made a plan and explained it to someone who then understands it. No points and no ranking — only a skill.
08I have a question
Do you still have a question? Write it here. It goes to your parent, not to strangers. Your parent confirms their e-mail first.
The form is loading… If it does not appear, write your question on paper and show it to a parent or teacher.
