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 part of the EM spectrum has the highest energy? | Gamma | 2. What part of the EM spectrum has the lowest energy? | Radio | 3. What part of the EM spectrum is used to communicate with satellites? | Microwave | 4. What part of the EM spectrum causes skin cancer? | UltraViolet | 5. What is a transverse wave? | A wave where the oscillations (vibration) are perpendicular to the wave direction | 6. What is a longitudinal wave? | A wave where the oscillations (vibration) are in line with the wave direction | 7. In which direction does the energy in a wave travel? | In the wave direction | 8. What would you hear if a sound wave had a greater amplitude? | It gets louder | 9. What would you hear if a sound wave had a greater wavelength? | It has a lower pitch | 10. What would you hear if a sound wave had a higher frequency? | It has a higher pitch | 11. A water wave travels through a pond with a velocity of 1m/s and a frequency of 5Hz. What is the wavelength? | 0.2m | 12. The speed of sound is 330m/s (in air). When Ricky hears this sound his ear vibrates 660 times a second. What was the wavelength of the sound? | 0.5m | 13. Red light has a wavelength of around 6x10-7m. If its frequency is 5x1014 Hz what is the speed of light? | 300 000 000m/s | 14. What is the equation to calculate the speed of a wave? | speed = frequency x wavelength | 15. What is the equation to calculate the frequency of a wave? | frequency = speed / wavelength |
