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. How does the speed of a vehicle effect the force needed when braking? | Faster the vehicle, the greater the force required on the brakes to stop in a certain distance | 2. How do you calculate the resultant force? | Add all forces acting on the system together | 3. Massx Acceleration= | Resultant Force | 4. On a distance/time graph, you can calculate the speed by? | Working out the gradient of the line | 5. On a velocity/time graph, you can calculate the acceleration by? | Working out the gradient of the line | 6. What are the units for acceleration? | m/s2 | 7. How do you calculate acceleration? | change in velocity/time taken | 8. What equation links Current, power and potential difference? | P=IV | 9. What do we mean when we say a device transforms energy? | changes it from one form to another Eg kinetic to sound | 10. H - What is the triangle which links time, current and charge in coulombs? | Q=IT | 11. H - What is a coulomb? | 6.4 billion billion electrons | 12. H - What is one amp in electrons? | 6.4 billion billion electrons passing a point each second | 13. What is an isotope? | an element with a different number of neutrons | 14. Where does background radiation come from? | cosmic rays, medical procedures, air, food and drink, ground (any one of these for one mark) | 15. What is the plum pudding model? | Electrons randomly distributed within the atom | 16. Give an example of an isotope used in a nuclear reactor? | uranium 235, plutonium239 | 17. Whats the difference between fusion and fission? | Fusion joins small nuclei Eg H to make He, fission is the breakdown of large unstable nuclie, like in a nuclear reactor | 18. How does a chain reaction occur in a nuclear reactor - draw a picture. | see board for answer | 19. Draw and explain PD current graphs for a lamp and a diode | see board | 20. How many volts is the UK mains supply? | 240V | 21. How do materials that are insulators become statically charged? | Electrons are rubbed off the surface which means that the surface becomes positive and the thing doing the rubbing becomes negative due to the electrons |
