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. How many grams are in a 0.453 mole sample of Zn(OH)2?45.0 grams
2. 2. Predict the electron configuration for an element with 30 electrons.1s22s22p63s23p64s23d10
3. 3. How many electrons are in the outermost energy level of an electrically neutral atom of fluorine?7
4. 4. Does potassium (K) have more similar properties to sodium (Na) or calcium (Ca)? Justify your answer.Sodium because they are in the same group; elements in the same group have similar properties
5. 5. What is the correct formula for a compound formed between sodium and oxygen?It is Na2O, which is ionic.
6. 6. Predict the products for the following reaction: Ca + H2O ->Ca(OH)2 + H2
7. 7. What is the formula for tin (II) phosphate?Sn3(PO4)2
8. 8. Consider the combustion reaction equation: C4H10 + O2 - > CO2 + H2O When the equation is balanced, what will be the coefficient of O2?13
9. 9. Which has a higher ionization energy Si or S? And why?S, it has more protons and thus is going to be harder to remove electrons
10. 10. Which is a bigger atom Aluminum or Sulfur?Al because they are in the same period, but S has more protons
