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. Researchers recently discovered a gene in humans that previously was unknown to science. Which statement best explains why the gene probably was not discovered much sooner? | The technology used to study genes is still being developed. | 2. A scientist plans to investigate the nervous system of sea slugs. What should the scientist do first? | Review the research other scientists have done on sea slugs. | 3. Leslie’s science teacher told her she must take a flexible approach to solving problems. What did Leslie’s teacher most likely mean? | Leslie should be willing to consider many possible causes for her observations. | 4. A scientist discovers that a certain substance will be useful in treating nerve damage. What is the best way she can communicate her results to the scientific community? | She can publish her results in a scientific journal that covers issues relating to nerves. | 5. A scientist studied a species of fish. She found that when a certain nutrient was added to the diet of the fish just after hatching, the fish gained an average of 3 kilograms in the first year. What additional information is needed to determine whether the nutrient is affecting the growth of the fish? | how much newly hatched fish in this species gain in the first year without the nutrient in their diet | 6. A scientist studied the number of eggs a species of bird lays each year. He found that the most common number of eggs laid in a year is three. Which statistical measurement did the scientist find? | the mode of the number of eggs laid in a year | 7. Joanne’s science teacher cautioned the class to be skeptical when learning about new scientific discoveries. Why is it important to be skeptical about new discoveries in science? | because all scientific discoveries must be examined critically before they can be accepted | 8. Louis Pasteur discovered that the bacteria in a substance can be killed by heating the substance for a short period of time. Which of these practices benefited most from Pasteur’s discovery? | storing foods for longer periods of time | 9. In which situation would osmosis most likely occur in cells? | across a permeable membrane that separates solutions of different concentrations | 10. Which statement best describes the process of respiration? | Oxygen and sugar are used in the process that provides energy to cells; water and carbon dioxide are its waste products. | 11. What is a difference between mitosis and meiosis? | In mitosis, the products are identical to the parent cell, while in meiosis the products are different from the parent cell. | 12. In humans, B is the allele for brown eyes and b is the allele for blue eyes. Two brothers both have brown eyes, but one of them has both the B and b alleles while the other only has B alleles. Which statement is true about the brothers? | They have the same phenotype but different genotypes. | 13. What do scientists mean when they refer to a population? | all the interbreeding members of a certain species in an ecosystem | 14. Which relationship is mutualistic? | an ant that lives on a plant and defends the plant from other insects | 15. Which example describes a behavioral adaptation? | A bird builds its nest in the ash near a volcano. | 16. A forest is flooded when a natural dam breaks, leaving the forest floor under two meters of water. Which animal is most affected by the flooding? | a rabbit | 17. Which resource is most likely found in large amounts in forest ecosystems? | wood | 18. In a large forest with many animals, there are only a small number of bears. Which of these most likely limits the population of bears in the forest? | supply of food | 19. What is the main reason humans need nitrogen to survive? | Nitrogen is used in making the proteins in the body. | 20. Which statement best describes the roles of photosynthesis and respiration in the carbon cycle? | Respiration adds carbon to the atmosphere, while photosynthesis removes carbon from the atmosphere. | 21. Scientists have observed an increase in global temperatures over the past 100 years. Which phenomena do scientists believe contributes to the increase in temperatures? | an increase in certain gases released during the use of fossil fuels |
