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. universe, galaxy, solar system, star, planet | hierarchy of the universe | 2. galaxies contain billions of stars, a solar system consists of smaller bodies orbiting a star | How is a solar system different from a galaxy? | 3. Mercury, Venus, Earth, Mars | Identify the terrestrial planets | 4. The sun's gravity keeps them in orbit | Why do objects in the solar system revolve around the sun? | 5. rocky surface, few to no moons, no rings, small size | Describe 4 similarities of the terrestrial planets | 6. The Milky Way is a spiral galaxy | Sketch the Milky Way galaxy | 7. gaseous surface, large size, many moons, rings | Describe 4 similarities of the gas giants | 8. "dirty snowballs", orbit the sun in an elongated ellipse, have a tail when they are closer to the sun | Characteristics of comets | 9. made of rock and metal, most orbit the sun between Mars and Jupiter, too small and numerous to be called planets | Characteristics of asteroids | 10. made of rock and metal, fragments may enter the earth's atmosphere where they burn up or hit Earth's surface | Characteristics of meteoroids | 11. The formation of an island or erosion of the Grand Canyon | slow change in Earth's surface | 12. Landslide due to an earthquake, volcanic eruption | change that may occur rapidly | 13. made of basalt or granite, thin "skin" is Earth's outer layer | crust | 14. made of molten rock, thickest layer on which plates float | mantle | 15. made of liquid iron and nickel | outer core | 16. made of solid iron and nickel | inner core | 17. magma becomes heated and less dense, rises and begins to cool near Earth's surface, pushing on the crust, becomes more dense and sinks, the process repeats continually | steps in mantle convection | 18. lots of gas and dust so new stars can form, no definite shape | irregular galaxy | 19. contains only older stars, can be nearly round or more oval | elliptical galaxies | 20. has "arms", gas and dust, Milky Way is an example | spiral |
