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.

Describe what the capacity of a storage device refers to | The capacity refers to how much data can be held by the device | 5. What factor does the speed of data transfer rely on? | The speed of data transfer relies on the method of connection used. | 6. Name two types of connection interface | Two types of connection are USB and Firewire | 7. What does Mbps mean? | Megabits per second | 8. Describe the purpose of temporary data storage | It is used to hold data while it is moving between the processor and peripherals. | 9. Where is the data held during temporaty data storage. | It is held in an area of RAM within the interface called a BUFFER. | 10. What is an interface? | An interface is the hardware and associated software needed to allow for communication between the processor and its peripheral devices. | 11. Explain how a print buffer is used to compensate for the difference in speed between a Processor and a printer | A processor can send data faster than a printer can print it, so the print buffer can store the data and free the computer to proceed with its other tasks. | 12. Descibe what data conversion is | Data conversion is changing the data received from or sent to peripheral devices from analogue to digital and vice versa | 13. What is an analogue signal? | An analigue signal is an eletrical signal that varies between two limits. | 14. What is a digital signal? | A digital signal has two values - on or off (1 or 0) |
