QR Challenge: 7th Ch. 6 Plate Tectonics

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. all the continents were once part of a supercontinent	Pangaea
2. continents are in constant motion on the surface of Earth	continental drift
3. the mountain ranges in the middle of the oceans	mid-ocean ridge
4. the process by which new oceanic crust forms along a mid-ocean ridge and older oceanic crust moves away from the ridge	seafloor spreading
5. a state in which magnetized object, such as compass needles, will orient themselves to point north	normal polarity
6. occurs and the magnetic field reverses direction	magnetic reversal
7. a state in which magnetized objects would reverse direction and orient themselves to point south	reversed polarity
8. Earth's surface is made of rigid slabs of rock, or plates, that move with respect to each other	plate tectonics
9. the cold and rigid outermost rock layer	lithosphere
10. forms where two plates separate	divergent plate boundary
11. where two plates slide past each other	transform plate boundary
12. form where two plates collide	convergent plate boundary
13. the denser plate sinks below the more buoyant plate in a process	subduction
14. the circulation of material caused by differences in temperature and density	convection
15. rising mantle material at mid-ocean ridges creates the potential for plates to move away form the ridge with a force	ridge push
16. as a slab sinks, it pulls on the rest of the plate with a force	slab pull
