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. Q1. Which two genes are responsible for OCD?COMT and SERT
2. Q2. What does a faulty COMT gene do?Produces too little COMT protein - this should inhibit dopamine production so we end up with too high levels of dopamine
3. Q3. What do high levels of dopamine cause?Motivation to carry out compulsions
4. Q4. What does the faulty SERT gene cause?Low levels of serotonin, which causes the OFC to be overactive
5. Q5. What is the OFC short for?Orbitofrontalcortex
6. Q6. What does the OFC usually do?Sends stress/worry signals to the caudate nucleus
7. Q7. What does the caudate nucleus do?Filters irrelevant (non-emergency) signals from reaching the thalamus to be acted upon
8. Q8. Which symptoms would an overactive OCF cause?Obsessions
9. Q9. Which symptoms would a faulty caudate nucleus cause?Compulsions as irrelevant worry signals are sent to thalamus to be acted upon (resulting in compulsive behaviours)
