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
4. Cut them out and place them around your class / school.
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!
4. A detailed case study in how to set up a successful QR Scavenger Hunt using this tool can be found here.
Question | Answer |
| 1. How are the terms “molar mass” and “atomic mass” different from one another | “Molar mass” is used to describe the mass of one mole of a chemical compound, while “atomic mass” is used to describe the mass of one mole of an element or the mass of one atom of an element. | 2. Which is a better unit for expressing molar mass, “amu” or“grams/mole”? | “Grams/mole” is better, because any macroscopic amount of a substance is better expressed in grams | 3. Find the mass, in grams, of 1.00 x 1023 molecules of N2 | 4.65 g | 4. How many particles are there in 1.43 g of a molecular compound with a gram molecular mass of 233 g? | 3.69 x 10 | 5. What is the mass in grams of 1.56 moles of aspartame? | 3.4 x 10^-2 moles |
