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. Enzymes are used in biological detergents. Give the name of the enzyme that digest stains containing fats. | Lipase | 2. Describe the effect of increasing the temperature on the time taken by the existing detergent to remove the stain. | Fall then rise | 3. The new detergent works at a lower temperature than the existing one. Is the new detergent likely to be more ‘environmentally-friendly’ than the existing detergent? Explain the reason for your answer. | (Yes)any two from: less heat / energy / electricity / power required / used / wasted, conserves fuel supplies or less fuel used, less pollution from power stations | 4. Cystic fibrosis is an inherited disorder that can seriously affect health. Which one of these is affected by cystic fibrosis? Blood cell, membranes, kidneys, nervous system | Cell membranes | 5. Battery chickens produce more eggs per year than free-range chickens. Suggest one reason why. | Any one from: less / no movement, less / no heat loss, reference to selective breeding, reference to controlled / better / more feeding | 6. The animals that we raise for food are usually herbivores (plant eaters) rather than carnivores (flesh eaters). Explain why with two reasons. | Any two from: less steps in food chain, less losses of biomass / energy / examples of losses, cheaper to feed herbivores | 7. Chromosomes contain molecules of DNA. Genes are small sections of DNA. Each gene contains a code. What does a cell use this code for? | Any two from: to combine / use amino acids, in specific / particular / correct / right order, to manufacture protein / enzymes / hormones | 8. The hormone insulin is a protein. Insulin is produced in the pancreas and controls blood glucose concentration. Which organ in the body monitors blood glucose concentration? | Pancreas | 9. We now know that a lack of the hormone insulin causes diabetes. In the early twentieth century there was no known cure for diabetes. Frederick Banting and Charles Best carried out a number of experiments on dogs. In the first experiment they removed part of the pancreas from a healthy dog (dog A). They ground up the pancreas tissue and injected an extract into dog B, whose pancreas had been removed to make it diabetic. Dog B’s diabetes was not cured. Banting thought that an enzyme produced in the pancreas of dog A had digested the hormone before it was injected. Name the enzyme that might have been responsible for digesting the hormone. | Protease |
