QR Challenge: More electron fun

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

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. What is the principle that states it is impossible to determine an electrons exact location? Heisenburg
2. The regions of space that electons reside in are called?2orbitals
3. The S orbital is what shape?3sphere
4. The principal quantum number is a reflection of _______ ?4energy
5. How many electrons can fill the P block elements?56
6. How many electrons can fill d block elements?610
7. What is the Aufbau principle?7 electrons fill the lowest energy levels first
8. What is Hund's Rule? 8 Electrons are placed into orbitals so that no pairs are put together unless it is necessary
9. What is the Pauli Exclusion Principle?9 Electrons have opposite spins
10. What is the old fashioned term for "combining power" of an element?10 Valence electrons
11. What are the commonalities of elements in the same column on the periodic table?11 Same shape, valence electrons and properties.
12. What is the valence shell?12 the number of electrons in the outer s and p orbitals
13. What is the octet rule?13 the s and p orbitals have 8 electrons and the elements have stability.
14. Given what you know about electrons why are the elements like Helium and Argon and neon less likely to form compounds with other elements?14 The valence shell is full.
