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. Describe chemical and physical change | chemical = new product made and the atoms rearrange to chemically make new products and irreversible, physical = change of state and reversible | 2. Describe a compound and an element (give examples) | compound = 2 or more elements chemically joined together eg iron oxide, element= all the atoms are the same and found on the periodic table eg iron, gold | 3. Describe the salts formed when metals react with hydrochloric, sulphuric and nitric acid | chloride, sulphate and nitrate | 4. Describe who came up with the periodic table and how they organised it | Dimitri Mendeleev organised by atomic number and properties | 5. Who was John Dalton and what were his ideas about atoms? | atoms of the same element are the same, everything is made up of atoms, compounds ae formed from 2 different atoms chemically joining together | 6. Describe three chemical properties | pH, reactivity with water/oxygen/acid | 7. Describe three physical properties | appearance, state, conductivity | 8. Explain how metals react with oxygen giving examples | metal + oxygen = metal oxide | 9. Explain how metals react with water giving examples | metal + water = metal hydroxide + hydrogen | 10. Explain the reactivity of the group 1 elements and how we can predict how francium will react | more reactive down the group so we can predict francium will be the most reactive | 11. Calculate the average of the following results: 25, 23, 27, 27, 24 | 25.2 | 12. Write the chemical symbols for oxygen, cobalt, aluminium, tungsten and tin | O, Co, Al, W, Sn | 13. Explain the 4 signs of a chemical reaction | temperature, colour, smell and gas | 14. Give examples of 4 metal and 4 non-metals | iron, sodium, calcium and gold v oxygen, sulphur, neon and carbon | 15. Describe 4 properties of non-metals | malleable, ductile, sonorous, conduct electricity and heat, shiny | 16. Balance the chemical symbol equation for Cu + HCl -> CuCl + H2 | 2Cu + 2HCl -> 2CuCl + H2 | 17. Analyse the graph of boiling points and describe the trend in full sentences | boiling points increase down group 7 | 18. Balance the chemical symbol equation for respiration C6H12O6 + O2 -> CO2 + H2O | C6H12O6 + 6O2 -> 6CO2 + 6H20 | 19. Describe melting | solid to a liquid | 20. Describe condensation | gas to a liquid | 21. State the halogens | fluorine, chlorine, bromine, iodine, astatine | 22. Describe the properties of the noble gases | non-reactive, stable, gases, shine a different colour when electricity is passed through them | 23. Explain the order of the alkali metals, describing the reactivity | Lithium, sodium, potassium, rubidium, caesium, francium | 24. Explain how catalysts work | speed up reactions without being used up | 25. Explain alloys and give examples | mixture of metals eg steel, durillium | 26. Analyse and explain how you can detect a pure substance | melting point data, pure=specific melting/boiling point | 27. Compare rusting and corrosion | rusting is iron reacting with oxygen and water, corrosion is any other metal reacting with oxygen |
