There will also be micro:bit prizes for regional, individual, or team runners-up.

You can read the full challenge Terms & Conditions here.

This could be a device that will reduce the amount of plastic used in your school. Or a solution that encourages people to look after the trees in their community. We've created resources to inspire you based on Goals 14 and 15 but you can work towards any of the Goals.

Whatever the issue, we’re interested to hear how you would go about solving it. Use your imagination and be as creative as possible!

To enter the challenge, you will need:

• a written entry describing what your solution is for. Which Goal have you focused on? What have you created? Why have you created it? Who is it for and how will it help your community or another community? (no more than 500 words)
• a paper prototype showing how your idea will work. This should be a photograph of your plans. Perhaps draw your solution with notes on how it will work
• OR a .hex file of your prototype code
• you can also include a video or photos of your project in action if you want to

You can code your device using the MakeCode block and text-based editor or the Python text-based editor.

If you don’t have a micro:bit you can still enter the challenge. Test your ideas using the MakeCode editor simulator and send us your paper protoype.
