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. True of false. RNA is a double strand. | False. It is a single strand. | 2. True of false. RNA contains uracil. | True. | 3. True of false. RNA contains deoxyribose sugar. | True | 4. What are the 3 types of RNA? | tRNA, mRNA, and rRNA | 5. a large D subscript o represents (radiosensitivity/radioresistance) | radioresistance | 6. In a linear nonthreshold dose response curve, the curve exhibits a (deterministic/stochastic) effect. | stochastic | 7. True or false. In a sigmoid, threshold dose-response curve, there is no recovery associated with lower doses. | false. There is partial recovery. Bushong 484 | 8. True or false. In a sigmoid, threshold dose-response curve, usually there is an upward point at the highest dose. | false. There is a downward turning point. | 9. in a sigmoid, threshold dose-response curve, the curve exhibits (deterministic/stochastic) behavior. | deterministic | 10. True or false. In a sigmoid, threshold dose-response curve, you have to reach a certain dose before you will get a specific effect. | true | 11. True or false. Cancer is a long term somatic effect. | true | 12. True or false. Cataracts are a long term somatic effect. | true. | 13. True or false. Life span shortening is a long term somatic effect. | true | 14. What are the three dose modifying factors of late radiation effects? (hint one is dose) | dose, dose rate, and species variation. | 15. What are the 3 stage of lethality or response? (think whole body exposure, syndrome stages) | prodromal, latent, manifest. | 16. Why do hydrogen and hydroxyl ions present minimal danger of biologic damage? | They can easily recombine to form a water molecule. | 17. The measure of cell radiosensitivity on a survival is curve is the definition of what? | Do | 18. The dose of radiation that will kill 63% of the irradiated population is the definition of what? | D37 | 19. The maximum sublethal damage, measured on the shoulder of the cell survival curve is the definition of what? | Dq | 20. Hemopoietic syndrome is an (early/late) effect. | early | 21. Erythema is an (early/late) effect. | early | 22. Childhood malignancy is an (early/late) effect. | late | 23. Bone cancer is an (early/late) effect. | late | 24. Nausea and vomiting are an (early/late) effect. | early | 25. Prenatal death is an (early/late) effect. | early | 26. Cataracts are an (early/late) effect. | late | 27. As radiosensitivity increases, LET (increases/decreases) | increases | 28. As the mass of a particles increases, LET (increases/decreases) | increases | 29. As LET increases, RBE (increases/decreases) | increases | 30. As radiosensitivity increases, OER (increases/decreases) | increases | 31. Radioprotectors (increase/decrease) sensitivity of the tissues. | decrease | 32. As dose rate decreases, RBE (increases/decreases) | decreases | 33. As the extrapolation number decreases, the cell's radiosensitivity (increases/decreases). | increases. The extrapolation number measures the cell's capacity to withstand damage. | 34. Death occurs in some, but not all (Hematopoietic/GI/CNS) | hematopoietic | 35. 10-50 Gy exposure (Hematopoietic/GI/CNS) | GI | 36. 2-10 Gy exposure (Hematopoietic/GI/CNS) | hematopoietic | 37. 50+ Gy exposure (Hematopoietic/GI/CNS) | CNS | 38. Death occurs within hours to 3 days (Hematopoietic/GI/CNS) | CNS | 39. Death occurs within 4-10 days (Hematopoietic/GI/CNS) | GI | 40. Decreased blood count is a key factor (Hematopoietic/GI/CNS) | hematopoietic | 41. Drastic decrease in fluids (Hematopoietic/GI/CNS) | GI | 42. Infection and death of crypt cells are a key factor (Hematopoietic/GI/CNS) | GI | 43. Burning sensation of the skin (Hematopoietic/GI/CNS) | /CNS |
