It is assumed that you have first completed the Non-communicable disease introductory lesson.


In this lesson students consider the importance of regular exercise to help to prevent heart disease. They work in small groups to come up with some initial ideas for tech devices to help people take more regular exercise before evaluating their ideas and choosing their favourite(s).

Creative thinking

  • Working in small groups with large pieces of paper, invite students to brainstorm ideas for the challenge to design a device to help people take more regular exercise (slide 6). Encourage them to be really creative at this stage and explain they can refine their ideas to focus on the micro:bit later.
  • Depending on their age and time available, you could ask them to come up with / give them a group name (e.g. Code Cookies, Tech Terriers).

Presenting ideas

  • Ask students to present their ideas back to the class and prompt thinking with questions tailored to your class (some ideas below - slide 7):
  • Which idea(s) would be most effective and why?
  • Who is your target user and why would they use it?
  • What barriers might there be to some of the ideas (cost, materials, technology, know-how etc) and how might these be addressed?
  • Would it be accessible for everyone? If not, how could it be adapted?

Evaluating initial ideas

  • Give students 5 minutes to evaluate their ideas (slide 7) and narrow them down or amend them to come up with a ‘top 3’ (or their favourite idea if you prefer). You may wish to use the worksheet to support this and talk through the example.

Lesson wrap up

  • Ask students to present their top 3 / favourite idea to the class and encourage the class to give feedback (2 stars and a wish / WWW/EBI etc). At this stage, their ideas may be wildly unworkable...don’t worry too much about that, it’s more about getting them to think creatively and have confidence giving/getting feedback.
  • Recap today’s learning (slide 8).

Extension / homework

  • Students could add to or begin a written or video blog, which could form part of their assessment.
  • You could start or add to a working wall for this topic and ask students to complete a design poster for their top 3 / favourite idea.



  • Consider groupings carefully to enable all students to participate. Pupils may need support with their evaluations of ideas and can be encouraged to make simple evaluative statements (e.g. which idea do they think is ‘best’? Why do they like that one most?).

Stretch & challenge:

Challenge students to consider their ideas more deeply and make more sophisticated evaluative statements. E.g. which idea is most fit for purpose and why? Which idea would be easiest for people to use and why is that likely to be important? Why would people use this as opposed to ideas currently on the market? How could people be encouraged to use it?

Opportunities for assessment:

  • Informal assessment of students’ ability to evaluate their ideas through questioning.
  • Formal assessment if wished of worksheets / blog.
