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 influences did Aristotle have on astronomy? | First solar system model, circular shape for the orbits. | 2. In doing so he solved what problem purposed by an earlier astronomer. What was that model? | Heliocentric. | 3. Describe Ptolemy’s “wheels on wheels” model for the solar system. | Planets moving on circular orbits on a circular path around the sun. | 4. Most of Copernicus’ ideas are still held true today. What was his biggest influence on the model of the solar system? | Heliocentric model | 5. What big change did Kepler make to Copernicus’ solar system model? | Elliptical orbits | 6. Galileo was a man of many trades. What influences did he have on astronomy? List at least 3. | Jupiter’s moon showing other things orbit planets, Venus’ phases, telescope. | 7. What roles does gravity play in the universe? | Holds everything together. | 8. Explain Kepler’s first law of motion. | Planets move in elliptical orbits with the sun at one focus. | 9. Kepler’s second law describes the speed at which planets move depending on their location. Explain at which point planets move fastest and slowest and why? | Perihelion, fastest, closest to the sun Aphelion, furthest, slowest, less area to cover in same amount of time. | 10. What two features of a planet’s orbit are factored into Kepler’s third law? | Orbital Period, Distance from the Sun. | 11. Explain how Newton’s Law of Universal Gravity applies to both large scale and small scale ideas. | Larger the mass the greater the gravity, the larger the distance, the smaller the gravity. | 12. What is the result of the planetary movement and gravity? | Inertia | 13. One way to compare the objects of space is by their relative sizes. What is larger than a galaxy? | Universe | 14. A large celestial body that is composed of gas and that emits light is a(n) ________________________. | Star | 15. A(n) ________________________ consists of one star or more than one star and all the objects in orbit around the central star. | solar system | 16. A(n) ________________________ is a large group of stars, gas, and dust bound together by gravity. | galaxy | 17. A galaxy contains stars, gas, and dust. This matter must be held together or the galaxy will break apart. What is responsible for holding the stars, gas, and dust together in a galaxy? | gravity | 18. What are the three main shapes that galaxies tend to take? | elliptical, spiral, irregular. | 19. What is found between galaxies? | voids | 20. Galaxies come in many sizes. How do we describe the range in size of galaxies? | from dwarf galaxies to giant galaxies |
