• Use the lesson's key objectives to create a list of success criteria together.

## Explore

### (small groups, 20+ minutes)

• Have your pupils use the example ideas from the activity brief as inspiration for their design ideas.
• Have each group select one design idea (of their own, or inspired by the example ideas) and build it.
• If they need additional help or guidance, refer them to the “Build it!” section of the activity brief.
• Have your pupils program their models to move and/or react.
• If they need additional help or guidance, refer them to the “Code it!” section of the activity brief.
