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. Draw and label a plant and animal Eukaryotes cell | mitochondria,cytoplasm,ribosome,cell membrane,nucleus,cell wall,vacuole,chloroplast | 2. Describe the job of the ribosome, mitochondria and nucleus | protein synthesis, aerobic respiration, contains DNA and controls the cell | 3. Explain what a prokaryote cell is and give an example | unicellular e.g. Bacteria,no nucleus free DNA, pili, flagellum | 4. Calculate the actual size of the object if the image size is 2mm and x450 magnification is used | 4.4micrometers or 0.004mm | 5. Compare the advantages and disadvantages of light and electron microscopes | light=cheap,better than human eye,electron=better magnification, resolving power, expensive | 6. Convert 3,500,000 to standard form | 3.5x106 | 7. Convert 2m to micrometers | 2000000micrometers | 8. Describe protein synthesis | ribosomes,mRNA,tRNA,transcription and translation | 9. Describe the structure of DNA | double helix, complimentary base pairs, phosphate sugar back bone | 10. Evaluate who made the biggest contribution to the discovery of the structure of DNA | either scientists as long as their is evidence to base your answer on | 11. Describe how an enzyme works and give 3 detailed examples | specific substrate, active site, chemical reaction produces product, biological catalyst that speeds up reactions, amylase, protease,lipase, DNA polymerase | 12. Analyse the graph of enzyme activity and explain the results | 20degrees optimum temperature | 13. Describe respiration using a word equation | expthermic and makes energy using oxygen + glucose -> carbon dioxide and water | 14. Compare and contrast anaerobic and aerobic respiration | anaerobic =no oxygen produces lactic acid or alcohol, produces less energy | 15. Balance the chemical symbol equation for respiration | 6o2 + c6h12o6 -> 6co2 + 6h2o | 16. Describe the 4 food tests and what a positive result looks like | iodine = black if starch present, benedicts = red if sugar present, Biuret =lilac if protein present, Alcohol = cloudy if fats present | 17. Describe photosynthesis using a word equation | how plants make food, carbon dioxide + water -> oxygen +glucose | 18. Explain what factors affect photosynthesis | light intensity, humidity, temperature,co2 conc and water | 19. Analyse what factors affect respiration giving examples | glucose intake and oxygen intake, e.g. RUnners and overweight people |
