📣 Phase 5 — Propagation 🎤 Presentations ⏱ 4 minutes

Task 9 — Group Presentations

Each group shares their investigation findings in 90 seconds. Show the visual, state one key finding, name one AI limitation you found. Audience: listen for one new idea, one question, and one connection to your digital life.

Step 1 — Scientist mindset
🔬
When scientists share findings
A framework for listening and presenting
When scientists share findings, they do more than present results. They explain what they learned, how they checked information, and where uncertainty remains.

As you listen to each group, pay attention not only to the answer — but also to the evidence they used and the limits of the AI support they relied on. This is critical thinking in action.
👂 Audience — listen for: one new idea you had not considered · one question you still have · one connection to something in your daily digital life

Step 4 — Group outputs

A summary of what each group investigated and their AI fact-check verdict. During the live lesson, the teacher's "Present" button switches a group's output to full-screen on the projector.

🔬
Group A — Scientist
How the eye detects colour
Key finding: Humans have three types of cone cells (S, M, L) each sensitive to blue, green and red light. The brain compares their signals simultaneously — like mixing three spotlights — to produce every colour we see.

Surprising fact: Mantis shrimps have 16 photoreceptor types, yet may be worse at distinguishing colours than humans.

Group B — Engineer
How screens produce colour
Key finding: Every screen pixel contains three sub-pixels (R, G, B). By controlling the brightness of each (0–255), screens produce 16+ million colour combinations — by exploiting the same three cone types in our eyes.

Surprising find: Red + Green light = Yellow. Mixing light is the opposite of mixing paint.
🔍 AI claim checked: ⚠️ Incomplete — omitted OLED vs LCD distinction

Group C — Health
Screens & eye health
Key finding: Blue light from screens suppresses melatonin by signalling to the brain that it is still daytime. Timing matters more than total hours — 20 minutes of bright screen at 11pm disrupts sleep more than 3 hours at 6pm.

Best habit: Stop screens 1 hour before sleep.

Step 5 — Wonder Feedback (for audience members)
Bridge to Task 10
"You have heard from all three groups. Now the whole class will co-create a Wonder Map together — adding one sticky note each to capture what mattered most from the entire lesson."
← Task 8 Continue to Task 10 →

What happens in Task 9

Each of the three investigation groups presents their output in 90 seconds using a structured scaffold: group angle, key finding, AI claim they checked and verdict. A 90-second countdown timer is visible only on the presenting group's devices. After each presentation, audience members complete a 3-prompt Wonder Feedback card. Students submit one feedback card per group (two total, since they do not submit feedback for their own group).

📋 Presentation structure — all groups

0–10s "Our group investigated [angle]."
10–50s Show visual output · state one key finding
50–80s "One AI claim we checked was… The AI was accurate / incomplete / misleading because…"
80–90s Closing connection: "This matters in daily life because…"

💬 Wonder Feedback Protocol

Three prompts per presentation — designed to build listening and critical thinking simultaneously: (1) one thing that changed your thinking, (2) one question you still have, (3) one connection to your daily digital life. Anonymous option available. Responses are delivered to the presenting group after the lesson ends via their portfolio.

♿ SEN Adaptations
  • Presentation mode text-to-speech available on the output panel display
  • Feedback form available in simplified language version with shorter sentence starters
  • Voice recording option for all three feedback response fields
  • Timer visible only to presenting group — no additional pressure for audience members
  • Scaffold prompts read aloud automatically on tap in accessibility mode
🖨️ No-Tech Format
  • Groups present using printed or hand-drawn outputs held up for the class
  • Feedback given on paper sticky notes using the 3 prompts written on the board
  • Teacher manages the 90-second timer verbally ("30 seconds remaining…")
  • Sticky notes collected and given to presenting group at end of lesson
📊 Teacher notes
  • Teacher has a remote navigation panel on their device to switch between group outputs on the projector
  • Wonder Feedback responses are collected anonymously (if toggle selected) or with first name only
  • All responses saved to teacher dashboard and delivered to presenting group after lesson ends
  • Gallery wall peer feedback option: teacher can export all feedback cards as a single printable PDF
