📝 Summative Quiz
⏱ 5 minutes
Task 11 — What Have You Learned?
Five questions across the whole lesson — science, technology, health, and AI ethics. One question per screen, no going back. Instant feedback where possible.
Summative Quiz — 5 questions
Think back across the whole lesson before you begin
Before you answer, take a moment to recall everything you explored today:
🌈
What you observed in the opening video about light and colour👁
What you learned about the eye's cone cells and the brain's role in colour🔬
What your group investigated — science, engineering, or health💡
What you discovered about screens, digital habits, and AI
📋 Rules: One question per screen · No going back · Q1–Q2 auto-marked with instant feedback · Q3–Q5 saved for teacher review · No time pressure — take your time.

Question 1 of 5
Auto-marked
What are the three types of colour-detecting cells in the human eye, and what light wavelength is each primarily sensitive to?
💡 Think back to the retina diagram and the slides from Phase 2.
A
Rods (red), Cones (green), Neurons (blue)
B
S-cones (blue), M-cones (green), L-cones (red)
C
Blue cones (UV), Green cones (visible), Red cones (infrared)
D
Pixels (red), Photons (green), Rods (blue)
Correct! The three cone types are S-cones (short wavelength — blue), M-cones (medium — green) and L-cones (long — red). Your brain compares signals from all three simultaneously to produce every colour you experience.
Not quite. The correct answer is S-cones (blue), M-cones (green) and L-cones (red). Rods detect brightness, not colour. The S, M, L naming refers to Short, Medium and Long wavelength sensitivity.
Question 2 of 5
Auto-marked
On a digital screen, what RGB combination produces the colour yellow?
💡 Think about the RGB mixer — remember, mixing light works differently from mixing paint.
A
Red + Blue (R:255 G:0 B:255)
B
Green + Blue (R:0 G:255 B:255)
C
Red + Green (R:255 G:255 B:0)
D
All three at full brightness (R:255 G:255 B:255)
Correct! Red + Green light = Yellow. This surprises most people because mixing red and green paint produces brown. But mixing light is additive — the colours combine rather than absorb. All three at full brightness produces white.
Not quite. The answer is Red + Green (R:255, G:255, B:0). Mixing red and green light produces yellow — which feels counter-intuitive because mixing paints gives brown. R+B = Magenta, G+B = Cyan, all three = White.
Question 3 of 5
Teacher review
Why does the Dress Illusion cause different people to see different colours, even when looking at the same image?
💡 Think about the role of the brain — and what assumption it is making about the light in the image.
0 / 200
🔍 Your teacher will review this answer using a 4-point rubric: (1) names the role of the brain; (2) mentions assumptions about lighting or context; (3) links to the concept of colour perception vs colour reality. Saved to your portfolio.
Question 4 of 5
Teacher review
Name one scientifically supported health effect of too much screen exposure, and explain the biological reason it happens.
💡 Think about blue light, melatonin, eye strain, and the circadian rhythm from Phase 3 Group C.
0 / 200
🔍 Assessed on: (1) valid health effect named; (2) correct biological mechanism explained (e.g. blue light → S-cone stimulation → melatonin suppression → delayed sleep onset). Saved to your portfolio.
Question 5 of 5 · AI Ethics
Teacher review
Describe one situation where using AI for science research is genuinely helpful, and one situation where you should be cautious about what the AI tells you.
💡 Think about your group's AI fact-check experience. What did the AI get right? What was incomplete or uncertain? This is the central learning outcome of the lesson.
A
One situation where AI is genuinely helpful for science research:
0 / 150
B
One situation where you should be cautious about the AI's response:
0 / 150
🔍 5-point rubric: (1) valid helpful use case; (2) valid cautious case; (3) reasoning linked to lesson experience; (4) understanding of AI limitations; (5) nuanced rather than binary thinking. This is the central DigComp learning outcome.

What happens in Task 11
A 5-question summative quiz covering the full lesson arc. Questions appear one at a time with no back navigation. Q1–Q2 are multiple choice, auto-marked with instant animated feedback and a minimum 3-second display time before the next button appears. Q3–Q4 are short text responses saved for teacher review. Q5 is a two-part AI ethics question — the central DigComp learning outcome. After submitting Q5, the personalised completion card animates in.
