Global Goal 15. life below water

Code Literacy



In this lesson you will:

  • Develop your 'code literacy skills' by coding a Micro:bit device
  • Consider solutions to the problems facing our oceans
  • Present your idea to the class
  • Discuss whether a knowledge of coding is something everyone should have.

Did you know...?

in 2015 world leaders signed up to 17 'Global Goals' aimed at making the world a better place by 2030. Goal 14 is Life Below Water'. What do you think this goal might aim to do? Brainstorm ideas.

Ready? Click the button to check:

Healthy oceans and seas are essential to our existence.They cover 70 percent of our planet and we rely on them for food, energy and water. Yet, we have managed to do tremendous damage to these precious resources. We must protect them by eliminating pollution and overfishing and immediately start to responsibly manage and protect all marine life around the world.

Watch the first 1 minute and 40 seconds of this video.
Were any issues you mentioned included?

Let's watch!

One of the targets is to reduce marine pollution.

How could we do this? Work in groups and brainstorm ideas. Try to come up with 12 ideas in three minutes!

Getting ideas

Narrowing down ideas

You have to create something that helps protect the oceans, and it must meet the following criteria:

  1. Be based around a Micro:bit, perhaps with a flashing light code.
  2. Be easy to make, requiring only a Micro:bit and everyday materials (aluminium foil, a lightbulb, string etc.)

In your groups, come up with a solution that meets this. You have 10 minutes!


Go to the Micro:bit website (purple button) and code you Micro:bit to do what you want it to do. No Micro:bit? Don't worry, you can use the simulator on the site.

Students will need access to one laptop per pair to work on this. If you don't have wifi in the classroom, don't worry, you can still code on the page if you have opened it previously.


Present your idea to the class. Listen to the other presentations and think of constructive feedback to give.

What do you think?

Have you noticed problems with the oceans where you live or on holiday? What were they?

What should be the key areas of focus?

Do you think digital technology can play a big role in solving these issues?

Should everyone learn some coding and be 'code literate'? Why?

you for participating!
