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. Most cells in the body of a grasshopper have 22 chromosomes. In some cells 11 chromosomes are found. What process produced those cells?Meiosis or Meiotic
2. 2. Where are egg cells formed and where are sperm cells formed?ovary AND Testis
3. 3. What type of cell division produces haploid (1/2 of the chromosomes) cells?Meiosis or Meiotic
4. 4. Give one important difference (other than the number of parents) between sexual and asexual reproduction.sexual reproduction more genetic variation
5. 5. Fusion of male and female gametes is called:fertilization
6. 6. Why must gametes be haploid?so you get half of genetic info from each parent
7. 7. If a gamete contains 8 chromosomes, how many chromosomes will a zygote (in the same species) contain?16
8. 8. List two times when mitotic cell division is required.cell repair and growth
9. 9. What type of reproduction is occurring in the photo (answer must be specific)? Asexual reproduction called budding
10. 10. Do flowers reproduce sexually or asexually?sexual reproduction
11. 11. What process is occurring in the picture?mitosis
12. 12. What process is occurring in the picture?meiosis
13. 13. What disease is caused by uncontrolled cell division?cancer
14. 14. Why is sexual reproduction advantageous to populations?genetic variation
15. 15. Name processes 1, 2 and 3.meiosis, fertilization, mitosis
16. 16. The diagram shows a body cell of an organism. Draw the cell that would result from meiotic cell division of this cell3 chromosomes
17. 17. During which part of the cycle does the breakdown of the thickened uterine lining occur?menstruation
18. 18. On or about which day is the egg released from the ovary?14
19. 19. Label part and 3 of the female reproductive system:uterus,ovary
20. 20. Where are reproductive hormones produced in females AND what is an example of a female reproductive hormone? Ovary AND Estrogen or progesterone
