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. How are muscle cells adapted to release a lot of energy? | Any two from:(contain) mitochondria, many (mitochondria), respiration (occurs in mitochondria) | 2. Which one of these is a chemical reaction that produces water in the body?: Breathing, osmosis, respiration, sweating | Respiration | 3. How does sweating help the body? | Cools / removes heat | 4. If the body loses more water than it gains, it becomes dehydrated. The concentration of the solution surrounding the body cells increases. This causes the cells to lose water. By which process do cells lose water? | Osmosis | 5. Fructose syrup is much sweeter than glucose syrup. Why do manufacturers of slimming foods use fructose syrup rather than glucose syrup? | Less needed to get same effect | 6. Here are some of the properties of enzymes:they all work at atmospheric pressures, they are easily broken down by high temperature or the wrong pH,they are soluble in water, so it may be difficult to separate them from products, they are expensive to buy, they work well at 25–45 °C. Using only this information give two advantages of using enzymes in industry. | They all work at atmospheric pressures they work well at 25-45°C | 7.

If a tuna eats 1 kg of herring, it gains about 65 g in mass. Give two reasons why so little of the mass of the herring is converted into mass of the tuna. | any two from: waste / excreted / urine / faeces / CO2(from tuna), respiration (of tuna), movement (of tuna) / hunting, used for heat (production) (of tuna), not digested / absorbed | 9. Local authorities are encouraging people to recycle vegetable waste by converting it into compost. Compost is made by mixing the vegetable waste with soil in a large container. Decay occurs more quickly if the container has holes in the sides. Explain why. | Air / oxygen (can enter), for (aerobic) respiration | 10. Spreading compost on the soil between plants leads to better growth of the plants. Explain why. | (more) minerals / nutrients /salt(s) / ions or named mineral / element available |
