Teacher Notes

A. Prior to the lesson:

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

3. Print out the QR codes.

4. Cut them out and place them around your class / school.

B. The lesson:

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!

C. TIPS / OTHER IDEAS

4. A detailed case study in how to set up a successful QR Scavenger Hunt using this tool can be found here.

Questions / Answers (teacher reference)

Question

Answer

1. 1. Are visible cell and tissue changes unique to radiation exposure?No, many types of trauma will produce similar or the same changes.
2. 2. With acute effects, are cell changes reversible?Cell changes may or may not be reversible dependent upon dose and the proliferative capacity of the target
3. 3. Are chronic effects reversible?Chronic effects are due to irreversible damage and subsequent progressive changes or depletion or critical non-parenchymal cells such as blood vessels or stroma
4. 4. What are the two types of healing?regeneration and repair
5. 5. What is regeneration?damaged cells are replaced by the same functional cell type that was present before the irradiation occurred
6. 6. What is repair?the damaged cells are replaced by a different cell type which is non functional
7. 7. What are the clinical factors affecting the response of tissue to radiation?size of the dose, volume of tissue irradiated, and fractionation.
8. 8. True or false. The hemopoietic system includes lymph nodes, circulating blood, bone marrow, and radiosensitive stem cells.True
9. 9. An ambient response occurs (with/without) exposure to radiation?without
10. 10. What portion(s) of the spinal cord is the most radiosensitive?cervical & thoracic
11. 11. What dose in Gy produces permanent sterility in males and females?5Gy
12. 12. Genetic effects exhibit what kind of response?linear, dose, and dose rate dependent response
13. 13. True of false. Hair follicles are radioresistant.false
14. 14. True or false. Most circulating blood cells are radiosensitive?false
15. 15. True or false. Current theory supports the use of linear nonthreshold curves for diagnostic x-ray.True
16. 16. What is the most sensitive stage of the male sperm cell development?spermatogonia
17. 17. What is the most radiosensitive stage of the female ovum development?mature follicle
18. 18. What are the most radiosensitive mature blood cell type?Lymphocytes
19. 19. What are the most radioresistant mature blood cell type?Erythrocytes
20. 20. What are some examples of acute and chronic organ changes?acute: inflammation, edema; Chronic: obstruction
