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. Describe chemical and physical changechemical = 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 acidchloride, 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 propertiespH, reactivity with water/oxygen/acid
7. Describe three physical propertiesappearance, 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, 2425.2
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 meltingsolid to a liquid
20. Describe condensation gas to a liquid
21. State the halogensfluorine, 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 reactivityLithium, sodium, potassium, rubidium, caesium, francium
24. Explain how catalysts workspeed up reactions without being used up
25. Explain alloys and give examplesmixture 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 corrosionrusting is iron reacting with oxygen and water, corrosion is any other metal reacting with oxygen
