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. The intermolecular force in CaBr2 is _____? | ion - ion | 2. Which one of the following exhibits dipole - dipole attraction between molecules? XeF4, Br2, CO2, or BCl3 | XeF4 | 3. What types of intermolecular forces exist between NH3 and CBr4? | London dispersion and hydrogen bonds | 4. Of the following, H2, Cl2, N2, or Br2, which has the highest boiling point? | Br2 | 5. What types of intermolecular forces exist between Br2 and CCl4? | London dispersion | 6. What is the intermolecular force in CBr4? | London dispersion | 7. Of the following substances, Kr, CH4, CO2, or H2O, which has the highest boiling point? | H2O | 8. List the four major intermolecular forces in order from strongest to weakest? | ion - ion, hydrogen bonding, dipole - dipole and London dispersion | 9. Which of the following, H2S, PH3, NH3, or SiH4, should have the lowest boiling point? | SiH4 | 10. C12H26 molecules are held together by what intermolecular force? | London dispersion | 11. Elemental iodine (I2) is a solid at room temperature, what is the major attractive force that exists among iodine molecules? | London dispersion | 12. How do intermolecular forces effect the state of matter of a substance? | the stronger the intermolecular force the more likely the substance is to be a solid, weak intermolecular forces produce gases | 13. Relate the strength of London dispersion forces to the size of the particles involved? | the larger a molecule is the larger the London dispersion force | 14. Explain why water has a higher boiling point than methane, CH4? | Because water has hydrogen bonding and methane only has London dispersion | 15. Determine the intermolecular force for each compound and then determine which compound has the highest boiling point: O2, H2, NH3, and SO2? | O2 = London dispersion, H2 = London dispersion, NH3 = hydrogen bonding and SO2 = dipole - dipole and NH3 has the highest boiling point |
