## 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

• Bring these devices into the lesson.

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!

### Question

1. 1.The Earthquake - Magnitude of the quake: 9.0
2. 2.The Earthquake - Energy released by the quake: 480 megatons (a magnitude 9.0 earthquake releases as much energy as 32,000 magnitude 6.0 earthquakes)
3. 3.The Earthquake - Energy released by the quake compared to the nuclear attack on Hiroshima: 600,000,000 times the energy of the Hiroshima bomb
4. 4.The Earthquake - Size of the quake: 5th biggest in World history
5. 5.The Earthquake - Duration of strong shaking from the quake: up to 5 minutes
6. 6.The Earthquake - There were four warning earthquakes (foreshocks) in the days leading up the quake of magnitude: 6.0, 6.1, 6.1 and 7.2
7. 7.The Earthquake - Number of aftershocks: more than 900 (aftershocks from a 9.0 magnitude quake can last for years)
8. 8.The Earthquake - First aftershock: There were 3 aftershocks of magnitude 7.0 or greater within 45 minutes of the quake
9. 9.The Earthquake - The quake moved entire island of Japan (Honshu): 2.4 meters (8 feet) closer to North America
10. 10.The Earthquake - The quake shifted the Earth's axis: 10 cm (4 in) at least
11. 11.The Earthquake - The quake made earth days shorter by: 1.8 microseconds
12. 12.The Earthquake - Japan's earthquake warning system sent a warning to Tokyo residents: 1 minute before the quake hit Tokyo
13. 13.The Earthquake - The quake moved a 180 km wide stretch of seabed up: 8 meters (26 feet)
14. 14.The Tsunami - Peak tsunami height: 40.5 meters (133 feet) at Miyako — that's equivalent to a 13 storey building. The Japanese tsunami scale considers a 3 meter tsunami to be a major tsunami.
15. 15.The Tsunami - How far the tsunami made it inland: up to 10 km (6 miles) at Sendai
16. 16.The Tsunami - Total land area covered by the tsunami: 561 kilometers sq. (217 sq. miles)
17. 17.The Tsunami - Total area of icebergs the tsunami wave broke off of Antarctica: 125 square kilometers
18. 18.The Tsunami - Number of people who evacuated after the tsunami warning in the worst hit areas: only 42%
19. 19.The Tsunami - Designated tsunami evacuation sites that were hit by the wave: at least 101
20. 20.The Aftermath - Estimated cost of the disaster: US\$300 billion (biggest in World history)
21. 21.The Aftermath - Number of buildings destroyed: 45,700
22. 22.The Aftermath - Number of automobiles and trucks destroyed: 230,000
23. 23.The Aftermath - Number of people killed and missing: 15,828 deaths and 3,760 people missing
24. 24.The Aftermath - Number of children killed: 378 deaths and 158 children missing.
25. 25.The Aftermath - Number of children orphaned: 236 children
