Make a Micro:bit Monster and put it to work collecting data for you! In this lesson, learners will code a micro:bit to show a face and make sounds, as well as sense the ambient temperature. The learners can then design a papercraft monster to fit round the micro:bit, and decide where in the classroom or school they will put their monster.

They will then collect temperature readings from their monster over a time period, chart these on the provided graphs, and compare their graphs with others to answer questions such as: what is the hottest/coldest part of the classroom?; what is the hottest/coldest time of day in each location?; is the outside temperature too warm to wear a coat at breaktime?; when the classroom goes above/below a certain temperature, does it correlate with our ability to learn?


Learners at Duns and Chirnside Primaries in the Scottish Borders making their Data Monsters.

Materials required:

    • A set of microbits (learners can work in pairs if need be)
    • Laptops or ipads to create the code
    • Scissors, tape or glue, and coloured pens for creating the papercraft monsters
    • Printable handouts, papercraft templates, and graph templates, all available below.

Extension activities

    • Decide the temperature (and light range?) that your monster likes. Have it make a happy sound or face when it’s in its optimal range, and/or a sad sound or face when it’s outside of this range (for clues, see Microbit sunlight sensor resource).
    • Build a house for your monster to keep it in its optimal light and temperature zone.
    • If you’ve placed your monster outside your classroom, have it send its temperature readings to a central microbit via radio signal, so that you don’t have to keep leaving the room to check. (For help with this, see Microbit thermometer resource)

Micro:bits for P1-4!

The above activity is ideal for Level 2 learners (P5-7) but if you have a mixed-level class, or want to try using micro:bits with your P1-4 learners, we have a resource for you, successfully tested with First (and even Early) Level learners! Micro:bit Monsters for Early/First Level.
