CLASSROOM CLIMATE CHECKER

Designing with an AI partner: how do you guide an AI tool to build what you actually need?

MICROCHAT + MICRO:BIT · AGES 9 TO 12 · 60 MIN

TOO HOT? TOO COLD? JUST RIGHT?

BIG IDEA

WITH YOUR CLASS

You're the designer

A

MicroChat is your AI partner. It suggests code. You test it and decide.

Accept

It works and does what we need.

Revise

It's close, but needs changes.

Reject

It's wrong or broken. Start again.

Fill in your Prompt Journey card as you go.

BIG IDEA

WITH YOUR CLASS

Same topic, different words

B

Which device would be more useful on our classroom wall? Why?

PROMPT A

"Make the micro:bit show the temperature."

Only checks when someone presses A

PROMPT B

"Make the micro:bit show the temperature in Celsius every 2 seconds."

Keeps checking on its own

KEY IDEA Working code is not the same as correct code. A human tester decides.

MISSION

WITH YOUR CLASS

Mission: set our climate ranges

D

At what temperature does our classroom start to feel too cold? Too hot? We decide the numbers.

Too cold

below ____ °C

Comfortable

____ to ____ °C

Too hot

above ____ °C

ROUND 1

WITH A PARTNER

Round 1: Try MicroChat's first draft

F

STARTER PROMPT

"Make the micro:bit check the temperature all the time. Show a happy face if the room is comfortable, a sad face if it is too hot, and a confused face if it is too cold."

Three faces, three ranges

Prompter: types the prompt into MicroChat.

Tester: runs tests and fills in the Round 1 column.

ROUND 1

WITH A PARTNER

Predict, then run

G

PREDICT

• Read the code before you run it.
• What will it show right now?
• What number makes it switch to a sad face?

RUN 3 TESTS

1 On the desk

2 In warm hands, 30 seconds

3 Near a cold water bottle

Record predicted vs actual.

ROUND 1

WITH A PARTNER

Investigate: who chose the numbers?

H

INVESTIGATE

• Find the if blocks in the code.
• What exact numbers did MicroChat choose for too hot and too cold?
• Do they match our class ranges?

Decide: Accept, Revise, or Reject?

Who chose these numbers?

ROUND 1

WITH A PARTNER

Modify, then make

I

MODIFY BY HAND

• Click the MakeCode button.
• Change the numbers to our class ranges.
• Download and test again.

Our ranges: too cold below ___ °C, too hot above ___ °C

MAKE WITH MICROCHAT

"Also show the exact temperature number."

• Where did MicroChat put the new block?
• Is that how you wanted it to work?

Stop and think

The code ran with no errors. So why did most of us choose Revise?

ROUND 2

WITH A PARTNER

Round 2: More climate features

K

Temperature is only one part of climate. Swap roles, then ask MicroChat:

"Give me 3 ideas to make my Classroom Climate Checker measure more about our classroom."

Light level

Bright enough to read?

Noise level

Too loud to focus?

Alert sound

Warn us when it's too hot

ROUND 2

WITH A PARTNER

Prompt with Keep and Add

L

KEEP

"Keep my temperature faces: sad above 24 and confused below 20. Keep the temperature number."

ADD

"Add: when I press button B, check the light level. Show a sun if it is bright enough to read and a moon if it is too dark."

PREDICT

What new blocks will appear? Will MicroChat keep your Round 1 work?

Classroom Climate Checker · Hour of AI

ROUND 2

WITH A PARTNER

Run, then investigate

M

RUN

Press B in bright light

Cover the micro:bit and press B

Check the temperature number and faces still work

INVESTIGATE

"Explain the blocks you added in simple words."

• How does the new code work?
• Does the explanation match what the micro:bit does?

Decide: Accept, Revise, or Reject?

Classroom Climate Checker · Hour of AI

ROUND 2

WITH A PARTNER

Modify, then make

N

MODIFY

"My code does ___, but I wanted ___. Please fix it."

• Write one follow-up prompt that names the problem.
• Test again.

MAKE: PEER TEST

Swap micro:bits with another pair

Don't explain how it works

They share one thing that worked well and one that was confusing

INQUIRY & REFLECTION

WITH YOUR CLASS

Compare your journeys

P

With another pair, compare your Prompt Journey cards. Where did you Accept, Revise, or Reject, and why?

Who caught the AI changing something you didn't ask for? How?

When should you accept what an AI suggests, and when should you check or change it?

Exit ticket: "If a friend was using AI to help build a project, I'd tell them ___."
