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. Task number 1: Remembering back to biology class, what is equilibrium?1
2. Task number 2: the symbols ⇋ or ⇆ are often used to represent what is called dynamic equilibrium. Using these symbols, what do you think dynamic equilibrium is?2
3. Task number 3: Now the real question: What causes reactions to go backwards? Why does equilibrium occur? Describe why in your own words? 3
4. Task number 4: If a reaction tends to favor making things out of the reaction the reaction is said to shift to the ____________________- because it is favoring the _________________ 4
5. Task number 5: If a reaction tends to favor recreating the initial chemicals the reaction is said to shift to the ____________________- because it is favoring the _________________ 5
6. Task number 6: The equilibrium constant capital letter K is equal to the concentrations of the products raised to their coefficients over the concentrations of the reactants raised to their coefficients. Write me a sample equation for this6
