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. Atoms are a fundamental piece of matter.1
2. Everything is made of matter and therefore composed of atoms.2
3. There are three particles inside of an atom-Proton,Electron,Neutron3
4. Protons are positive (+)4
5. Electrons are negative (-)5
6. Neutrons are neutral (0) they have no charge6
7. The nucleus is in the inside of the atom7
8. The protons and neutrons are in the nucleus8
9. The electron cloud is the space outside the nucleus9
10. The electrons are in the cloud in shells or levels10
11. The particles in the atom are weighed in amu’s11
12. Protons and Neutrons each weigh around 1 amu12
13. Electrons weigh 1/1836 of an amu!!13
14. We will look at 3 levels or shells in the electron cloud14
15. The 1st level can hold 2 electrons15
16. The 2nd level can hold 8 electrons16
17. The 3rd level can hold 8 electrons17
18. In a neutral atom, you have the same number of protons and electrons.18
19. To help you remember this think: APE 19
20. A is Atomic Number, found above the element symbol20
21. P is Proton Number21
22. E is Electron Number22
23. To find neutrons think: MAN23
24. M is for Mass Number (also called atomic mass)24
25. A: Atomic Number25
26. N is the number of neutrons26
27. Subtract A from M to get neutrons27
