## 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!

## 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.

5. Time yourself on how quick you can run 100m, how long would it take to run 1km? Give reasoning.
6. Watch this video. https://www.youtube.com/watch?v=dJpIU1rSOFY. Find out the greatest magnitude earthquake recorded? Is it in the Southern or Northern hemisphere?
7. Watch this video. https://www.youtube.com/watch?v=qLvLFdy6lVI. Why do you think it only takes 15cm of water to knock down a person and 60 cm to move a car?
8. How do they work out the speed in which the water is flowing? Why do you think this?
9. Construct an infrastructure, using proper measurements that you think will be secure during a flood, provide a reason (draw).
10. Build an earthquake resistant building using the materials provided. Take into consideration the height, length and structure of the building, why did you build the infrastructure like this? (take a photo using your camera
