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.

| 1. The general equation for strain is change in length divided by the original length of the object. Two of the most common types of stress and strain are tensile and compressive stress and strain. If we were to create two separate equations for tensile and compressive stress, what would the difference between them be? | 1 | 2. Why do we say that force is a vector quantity? | 2 | 3. When solving a statics problem, what is the very first step we take? | 3 | 4. In the absence of friction, how much energy would be lost as a rollercoaster car goes down the first of several 'hills'? | 4 | 5. A heated pot of water exhibits what kind of energy? | 5 | 6. Power is a measure of how much...? | 6 | 7. Entropy is a measure of how much...? | 7 |
