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. What is a wave? | A disturbance in a medium that transfers energy from one place to another. | 2. Describe the transfer of energy through a slinky held by you and your bff. | hand 1, slinky, hand 2 | 3. An earthquake travels through what medium? | the ground | 4. What does a wave carry? | Energy | 5. Draw a wave diagram and label the crest, trough, amplitude, wavelength and rest position. | diagram with properties labeled | 6. What happens to the wavelength of a wave if the frequency increases? | it gets shorter or decreases | 7. What causes amplitude to increase? | energy is added to the wave | 8. What happens to a sound wave if the amplitude increases? | the sound gets louder | 9. What is wavelength? | the distance between two identical points (crest and crest or trough and trough) | 10. What is a certain number of waves per second? | the frequency of the wave | 11. What is the relationship between frequency and wavelength? | the lower the frequency, the longer the wavelength. The higher the frequency, the shorter the wavelength. | 12. What is the relationship between amplitude and frequency? | there is none | 13. For sound, what is the relationship between the rate of vibration and pitch? | the faster the vibration, the higher the pitch | 14. If you have a long string on a harp, what will be the pitch and rate of vibration? | low pitch, slow vibration | 15. What is the relationship between frequency and pitch? | the higher the frequency, the higher the pitch | 16. What is the Law of Reflection? | the angle of incidence equals the angle of reflection | 17. What is refraction? | the bending of light waves due to a change in speed | 18. If the light travels from water to air, what will happen to the speed and direction of the light ray? | it will speed up, causing it to bend away from the normal line | 19. If you look at a red apple in white light, what colors are reflected and which are absorbed? | red is reflected and all the rest are absorbed |
