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
4. Cut them out and place them around your class / school.
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!
4. A detailed case study in how to set up a successful QR Scavenger Hunt using this tool can be found here.
Question | Answer |
| 1. The process by which our sensory receptors and nervous system take in stimuli from our environment | Sensation | 2. The process of converting one form of energy into a form your brain can use | Transduction | 3. The minimum stimulation needed to detect a particular light, sound, pressure, taste or odor 50% of the time | Absolute Thresholds | 4. Stimuli below our absolute threshold for conscious awareness | Subliminal | 5. The minimum difference between two stimuli required for detection 50% of the time(aka, Just Noticeable Difference) | Difference Threshold | 6. The principle, that to be perceived as different, two stimuli must differ by a constant minimum proportion, rather than a constant amount | Weber's Law | 7. When you walked into school today, you noticed a bad odor. Over time, you stopped noticing the odor. What principle explains this? | Sensory Adaptation | 8. What does a light's wavelength (the distance from one wave peak to the next) determine? | It's hue/color | 9. What does a light wave's amplitude (height) determine? | Intensity/amount of energy it contains | 10. The doughnut-shaped ring of muscle that adjusts the size of the pupil (and determines eye color) | Iris | 11. Controls the amount of light entering your eye | Pupil | 12. Protective covering of your eye | Cornea | 13. The inner surface of your eye, on which the image is focused | Retina | 14. Which receptor cells in the eye allow us to see color? | Cones | 15. Cats can see well in the dark. Therefore, they have more of a certain type of receptor cell in their eyes. What are these receptor cells called? | Rods | 16. What causes the blind spot that results from the lack of receptor cells in a part of your eye? | The optic nerve leaving the eye | 17. The tight membrane in your ear that vibrates when receiving sound waves | Eardrum | 18. A snail-shaped tube in the inner ear which contains liquid and hair cells. These hair cells trigger nerve impulses | Cochlea | 19. Hearing loss results from any prolonged exposure to sounds above how many decibels? | 85 | 20. What are the senses of taste? | Sweet, sour, salty, bitter, umami | 21. Smell can change our perception of taste. This phenomenon is called what? | Sensory Interaction | 22. The system for sensing the position and movement of body parts | Kinesthesis | 23. The sense of body movement and position, including the sense of balance | Vestibular Sense |
