Facilitator’s Guide: AIR Unit 3 — Sailing Home
Two lessons to close the AIR arc: read two sources that disagree, build a sensing robot, then finish with the Xello career check-in.
📅 2 lessons🤖 RVR + micro:bit🏆 110 points in the module
The unit at a glance
| Module item | What happens | Points |
|---|---|---|
| Lesson 1: Conflicting Viewpoints | A short video, then two articles that reach opposite conclusions about ocean plastic. Students fill an AEIOU organiser on the worksheet, capturing what each text claims and what it leaves out. | 5 |
| Lesson 2: RVR + micro:bit Temperature Bot | A walkthrough video, then students mount a micro:bit on the RVR and code a temperature bot — the sensor reports a number, their code decides what counts as too hot. The only lesson in the course that uses both devices at once. | 100 |
| Closing | ||
| Xello Check-in: Explore Career Matches Lesson | The Xello lesson on why the career matches came out the way they did, then a screenshot of the completion screen. Runs last. | 5 |
Materials + prep
- AI Ethics Debate is an optional extension in Enrichment · Parked Alternates. Use it when you want another discussion day. The core route closes with Temperature Bot and the Xello check-in.
- RVRs charged and micro:bits with battery packs, together, for Lesson 2. Both devices, same day, same table.
- Both Lesson 1 articles opened and skimmed. They genuinely disagree, and knowing which evidence each one selects is what makes the discussion work.
- Google Assignments launched once for Lessons 1 and 2 so you have seen the worksheets.
- Xello through ClassLink for the closing check-in.
Watch-fors
- Lesson 2 assumes two earlier units. It expects students to know the RVR from RVR Robotics (AIR Unit 2) and the micro:bit from AIR Unit 1: Leaving Land. Run those first, or budget a period for re-teaching the download step before anybody mounts anything.
- The Xello check-in has prerequisites inside Xello. It needs the Matchmaker quiz from the SW1 check-in and three saved careers from the SW2 check-in. Without both, the lesson stays locked and the student cannot finish — check that before the period, not during it.
Grading
Lesson 2: RVR + micro:bit Temperature Bot is the unit’s Major grade, at 100 points. Lesson 1 and the Xello check-in are Minor grades, 5 points each, so the module holds 110 points. Lessons 1 and 2 come back as Google Assignments worksheets. The Xello check-in is a screenshot upload.
