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. What is the meaning of catalyst?catalyst is a substance that can speed up the rate of reaction without getting consumed in the process
2. Why catalyst can be used to speed up a chemical reaction?because catalyst can provide an alternative pathway with low activation energy (It can decrease the activation energy)
3. In general, how many kind of catalyst?2
4. Mention the kind of catalyst based on the phase of catalyst!heterogeneous and homogeneous catalyst
5. What is the meaning of heterogeneous catalyst?a catalyst has different phase with the reactant used
6. a catalyst has the same phase with the reactant used can be called as..homogeneous catalyst
7. Manganese (IV) oxide is a kind of catalyst that can be used for?decomposing hydrogen peroxide substance (H2O2) to water and oxygen gas
8. What is the catalyst used for manufacturing ammonia gas?Iron catalyst
9. Nickel can be used as a catalyst for..making margarine
10. What is the example of biological catalyst?enzyme
11. Mention five advantages the using enzyme as catalyst!Enzyme is more efficient, Its more specific, It doesn't produce byproduct, It can take place under very mild condition, the amount of enzyme can be regulated according to need
12. What is the meaning of substrate?substrate is the substance that fits onto the active site of an enzyme and react to form a product
