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. The angle of depression from the top of a castle to a boat is 25 degrees. If the distance from the boat to land, across the water, is 50m, then how high is it to the top of the castle? | 23.3 m | 2. A ship is 130 m away from the center of a barrier that measures 180 m from end to end. What is the minimum angle that the boat must turn to avoid hitting the barrier? | 35 degrees | 3. If the sin of angle A is 4/5, then what is the cos A? Hint:What is sin equal to in words? What can you use to find the missing piece of the triangle? | 3/5 | 4. Use the picture to the side to help you answer the question. Label the information you know to help determine what you are looking for. Two students want to determine the heights of two buildings. They stand on the roof of the shorter building. They measure the angle of elevation to the top of the taller building to be 44 degrees. From the same spot the students measure the angle of depression from the shorter building to the ground to find it measures 53 degrees. The students then measure the horizontal distance between the two buildings is 18 m. How tall is each building? | The shorter building is 23.88 m and the taller building is 41.26 m. | 5. Create your own problem and provide solution. | Answers will vary |
