QR Challenge: Fertilisation and Menstruation

Created using the ClassTools QR Treasure Hunt Generator

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

• Download a QR reader (e.g. I-Nigma | NeoReader | Kaywa) onto their mobile devices
• Bring these devices into the lesson.

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!

Questions / Answers (teacher reference)

Question	Answer
1. Gland that produces and releases hormones	Endocrine Gland -
2. Pituitary Hormone that promotes sperm production in males and the development of a follicle in females	Follicle stimulating hormone (FSH)
3. First stage in the menstrual cycle	follicular
4. Region of the brain that secretes releaser hormone at puberty	hypothalamus
5. Second Stage of the menstrual cycle when follicle develops into corpus luteum.	luteal phase
6. Hormone that triggers ovulation and corpus luteum development.	Luteinising hormone
7. 28 day cycle in the middle of which ovulation occurs. First day of menstruation regarded as day one.	menstrual cycle
8. Removal of the endometrium and an unfertilized egg cell	menstruation
9. High levels of the ovarian hormones inhibit the pituitary gland and therefore prevent the secretion of FSH and LH which prevents further follicles from developing.	Negative feedback in females
10. Gland in the brain that releases many hormones	Pituitary gland
11. Produced in hypothalmus, stimulates pituitary gland to release FSH, LH and ICSH. Triggers puberty.	releaser hormone
12. Hormone that stimulates sperm production and activates the prostate glands and seminal vesicles.	testosterone
13. Release of an egg from a follicle in the ovary, usually occurs at midpoint of menstrual cycle.	ovulation
14. Ovarian hormone that stimulates proliferation of the endometrium in preparation for implantation. Peak levels stimulate secretion of LH.	oestrogen
15. Luteal stage of the follicle that secretes progesterone.	corpus luteum
16. Ovarian hormone that promotes further development and vascularisation of the endometrium in preparation for implantation. Low levels can lead to menstruation.	progesterone
17. Attachment of zygote to the lining of the uterus	implantation
18. Inner lining of the uterus	endometrium
19. If this occurs the corpus luteum does not degenerate and progesterone levels remain high	fertilisation
