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

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!

C. TIPS / OTHER IDEAS

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. 1. Where do hydrothermal vents form?along mid-ocean ridges
2. 2. What are the primary producers at hydrothermal vents?chemosynthetic bacteria
3. 3. What is the temperature like in hydrothermal vent communities?hot due to the hot water coming from vents
4. 4. Where do the producers live at the hydrothermal vents?inside mussels and tube worms
5. 5. What are the structures called that spew the hydrogen sulfide at hydrothermal vents?black smokers
6. 6. What is the ultimate source of energy at hydrothermal vents?chemicals such as hydrogen sulfide
7. 7. What happens to pressure as depth increases?pressure increases also
8. 8. What is chemosynthesis analogous to and why? Chemosynthesis is analogous to photosynthesis because they use energy to make their own energy and do not rely on other organisms for their food.
9. 9. What is the fastest growing invertebrate on earth?tubeworms
10. 10. What is the bright red structure of the tubeworm called that filters oxygen, hydrogen sulfide and carbon dioxide from the water?plume
11. 11. What is a light produced by a chemical reaction that does not produce heat called?Bioluminescence
12. 12. What are some uses for Bioluminescence?counterullumination, lure prey, sacrificial tag, smoke screen, warning coloration, illuminate prey so they can see them, mate attraction
13. 13. Is bioluminescence primarily a marine phenomenon?yes
14. 14. What are the deepest parts of the ocean called?trenches
15. 15. What is the continuous mountain chain called found throughout the ocean botton?mid-ocean ridges
16. 16. The flat areas of the seafloor are known as ________.abyssal plains
17. 17. Who is responsible for discovering the continental drift theory?Alfred Wegener
18. 18. Which ocean do scientist believe is getting larger due to plate tectonics?Atlantic Ocean
19. 19. What is occurring at mid-ocean ridges?seafloor is being created
20. 20. What is happening at trenches?seafloor is being destroyed
21. 21. Name and describe the 3 layers of the earth.core-center, mantle-middle layer, crust-outer layer
22. 22. Name the 3 plate boundaries.convergent-plates come together, divergent-plates pull apart, faults-plates slip past each other
23. 23. What is oceanic crust made of?basalt
24. 24. What forms at a convergent boundary?trenches
25. 25. What forms at divergent plate boundaries?mid-oeaan ridges
26. 26. What type of rock makes up the continents?granite
27. 27. Where is new crust formed?mid-ocean ridge
28. 28. Where is crust destroyed?trenches
29. 29. What type of ecosystem is found around mid-ocean ridges?hydrothermal vents
