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. Pulls on the crust, stretching rock so it becomes thinner in the middle | tension | 2. Landform created by tension | mid ocean ridge | 3. Type of plate boundary where tension stress occurs | divergent boundary | 4. Squeezes rock until it folds or breaks | compression | 5. Landform created by compression | mountain ranges | 6. Type of plate boundary where compression occurs | convergent | 7. Pushes rock in opposite directions | shearing | 8. Landform created by shearing | faults | 9. Type of plate boundary where shearing occurs | transform | 10. Strain in which a rock is permanently changed | plastic | 11. Vibrations in the ground that result from movement along faults, or breaks in Earth’s lithosphere | earthquake | 12. Fault caused at a divergent plate boundary | normal fault | 13. Two blocks of rock slide horizontally past each other in opposite directions | strike slip fault | 14. A strike slip fault occurs at which type of plate boundary | transform | 15. Force pushes two blocks of rock together with the rock above the fault moving up | reverse fault | 16. A reverse fault occurs at which type of plate boundary | convergent | 17. Point beneath Earth’s surface where rock under stress breaks to cause an earthquake | focus | 18. Point on the surface directly above the focus | epicenter | 19. Move slower than P and S waves, but can produce severe ground movement with a wavelike motion | surface waves | 20. Compression waves that travel through solids and liquids, compressing and expanding the material they pass through, temporarily changing volume | Primary waves | 21. Only travel through solids and temporarily change the shape, but not the volume of the material they pass through; move slower than P waves | Secondary waves | 22. Devices that measure and record ground motion and helps determine the distance seismic waves travel | seismometer | 23. Weak spot in earth’s crust where molten material, or magma, comes to the surface | volcano | 24. Area where material from deep within the mantle rises then melts, forming magma; a volcano forms above a hot spot when magma erupts through the crust (ex. Hawaiian Islands) | Hot Spot | 25. Magma has low silica content, flows easily and erupts quietly with gases bubbling out gently and lava oozing quietly | quiet eruption | 26. An eruption that hurls out ash, cinders and magma bombs | explosive eruption | 27. Fountain of water and steam that erupts from the ground when buildup of pressure is released | geyser | 28. Formed when groundwater is heated by a nearby body of magma or hot rock and eventually rises to the surface to collect in a natural pool | hot spring | 29. Geothermal Activity | Occurs when magma, a few kilometers, beneath Earth’s surface, heats underground water | 30. Which forces squeeze rocks together, causing them to fold or fracture | compression | 31. When rocks deform plastically under compression stresses they | break | 32. At which type of plate boundary boundary, do the world’s largest mountains grow | convergent | 33. The sudden release of energy stored in rocks creates | earthquakes | 34. The main reason there are so many earthquakes around the Pacific ocean basins is | the tremendous number of convergent plate boundaries | 35. To find an earthquake epicenter, a seismologist needs to know | the distances from three different seismic stations to the epicenter | 36. As stresses build in a region | the rocks deform plastically and then break | 37. Mountain ranges rise where there are | compressive stresses | 38. A useful earthquake prediction will include the quake's | timing,magnitude | 39. One reason fewer people die in developed nations than developing ones in the same magnitude earthquake is | the quality of construction is better | 40. Shear stress is the most common stress at transform plate boundaries | true |
