QR Challenge: structure of the eye
Teacher Notes
A. Prior to the lesson:
1. Arrange students into groups. Each group needs at least ONE person who has a mobile device.
2. If their phone camera doesn't automatically detect and decode QR codes, ask students to
- Download a QR reader (e.g. I-Nigma | NeoReader | Kaywa) onto their mobile devices
- Bring these devices into the lesson.
3. Print out the QR codes.
4. Cut them out and place them around your class / school.
B. The lesson:
1. Give each group a clipboard and a piece of paper so they can write down the decoded questions and their answers to them.
2. Explain to the students that the codes are hidden around the school. Each team will get ONE point for each question they correctly decode and copy down onto their sheet, and a further TWO points if they can then provide the correct answer and write this down underneath the question.
3. Away they go! The winner is the first team to return with the most correct answers in the time available. This could be within a lesson, or during a lunchbreak, or even over several days!

Questions / Answers (teacher reference)
Question | Answer |
| 1. question1 the large space in the eye filled with a thick transparent jelly that helps give the eyeball its shape | vitreous humour
|
2. question 2 the small space at the front of the eye filled with transparent gel that gives the cornea its shape | aqueous humour
| 3. question 3 tough clear structure that covers the pupil and the iris that bends light onto the lens behind it | cornea
| 4. question 4 the place where all the nerves from the retina join to form the optic nerve. there are no rods/light sensitive cells here so no image is formed | blind spot
| 5. question 5 muscle that controls how much light enters the pupil | iris
| 6. question 6 muscle that controls the shape of the lens, connected to the lens by suspensory ligaments | ciliary muscles
| 7. question 7 flexible curved transparent structure behind the pupil that can change shape refracting light from near and far objects differently focusing light onto the retina, cataracts can form in this if it loses its transparancy | lens
| 8. question 8 bundle of fibres that carry sensory information from the retina to the brain | optic nerve
| 9. question 9 opening to allow light through to the retina, the size of which is controlled by the circular and radial muscles of the iris | pupil
| 10. question 10 the thick, tough white outer covering of the eyeball | sclera
| 11. question 11 attached lens to ciliary muscle | suspensory ligament
| 12. question 12 black layer that prevents internal reflection of light | choroid
| 13. question 13 contains the receptor cells rods which are sensitive to light and cones which are sensitive to colour | retina
| 14. question 14 this yellow spot directly behind pupil has the biggest concentration of cone cells and is where we are most sensitive to colour | fovea
| 15. question 15 thin protective covering filled with blood vessels that works as part of the non-specific immune response | conjunctiva |
