QR Challenge: Waves - Characteristics and Properties

Created using the ClassTools QR Treasure Hunt Generator

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. In a transverse wave, this is the magnitude of height of a wave from origin to crest.	Amplitude
2. This is the increase in density of a medium due to wave travel.	Compression
3. This is the peak, or highest point, of a wave.	Crest
4. A propagating wave in space with electric and magnetic components. It may travel in a vacuum.	Electromagnetic Wave
5. The capacity for doing work. It may be transformed from one form to another.	Energy
6. This is the number of complete movements of a wave per second.	Frequency
7. This is a wave whose energy travels in the same direction as the energy being transferred.	Longitudinal Wave
8. This is anything with mass that occupies space.	Matter
9. A wave which needs a medium (solid, liquid, gas) in order to propagate itself.	Mechanical Wave
10. This is the material in which a mechanical wave travels.	Medium
11. This is the rate of distance traveled per unit of time, without regard to direction.	Speed
12. This is a type of wave that travels in one direction, but the energy travels perpendicular to this direction.	Transverse Wave
13. This the bottom, or lowest point, of a wave.	Trough
14. This is the back and forth motion of matter.	Vibration
15. A rhythmic disturbance that carries energy through matter or space.	Wave
16. This is the distance from the peak to a peak of a successive wave.	Wavelength
