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. What are three properties of magnets? p 158-159 (Hint: Look at the red headings) | Magnetic Forces, Magnetic Poles, Magnetic Fields | 2. What two things can magnetic force do? p 158 (Hint: Look under the red heading, Magnetic Forces) | Push or Pull | 3. Complete this statement. Like poles____________ one another, while opposite poles ________________. p 159 (Hint: Look under the red heading, Magnetic Poles) | repel, attract | 4. Where is the magnetic field the strongest? p 159 (Hint: Look under the red heading, Magnetic Fields) | The magnetic field is strongest at the north and south poles. | 5. How is the pole of a magnet similar to an electric charge? p 159 and p 129 (Hint: Think about poles or charges that are alike and different.) | Magnetic poles and electric charges can both attract and repel one another. | 6. What causes magnetism? p 160 (Hint: Look at the red headings.) | The type of atom and the formation of domains. | 7. Is it possible to make a magnet with only one pole by cutting it? p 160 (Hint: Look under the red heading, The Type of Atom) | No. If you cut a magnet, you get two new magnets, each with two poles. | 8. What do the domains of a nonmagnetic nail look like? p 160 (Hint: Look at the graphics on the left side of the page.) | The domains in the nonmagnetic nail point in all different directions. | 9. What do the domains of a magnetic nail look like? p 160 (Hint: Look at the graphics on the left side of the page.) | The domains in the magnetic nail are all aligned in the same direction. | 10. Identify three types of magnets? p 161 (Hint: Look at the three red headings on the page.) | Ferromagnets, Electromagnets, and Temporary Magnets. | 11. What might be some advantages of electromagnets over permanent magnets? p 161 (Hint: Look under the red headings, Electromagnets and Ferromagnets.) | Electromagnets can bet turned on and off. Te strength of the electromagnet can be controlled because it depends on the strength of the electric current. | 12. How is Earth like a magnet? p 162 and 163 (Hint: Look at the red headings.) | Earth has a magnetic field and magnetic poles. | 13. Why are auroras more commonly seen in places such as Alaska and southern Australia than in places such as Florida and Mexico? p 163 (Hint: Think about where the Earth's magnetic poles are located, and where Alaska and southern Australia are located.) | Auroras are most commonly seen near Earth's magnetic poles. Because Alaska and southern Australia are close to Earth's magnetic poles, people living in those places are more likely to see auroras than are people living in Florida and Mexico, which are far away from the Earth's magnetic poles. | 14. When cows are grazing, they may eat pieces of; metal, such as nails. Farmers can feed the cows a smooth magnet to attract such objects. What will this technique prevent? p 156 (Hint: Read the information under the picture of the cow.) | This will prevent the objects from moving farther through the cow's system and causing damage. | 15. Food manufacturers want to prevent small bits of metal from entering their product. How might magnets be used? p 156 (Hint: Use the information under the picture of the cow to give you an idea of what could be used.) | Sample Answer: Pass the food under a large magnet before packaging to remove any bits of metal in the product. |
