QR Challenge: ESS Benchmark Review Guide

Created using the ClassTools QR Treasure Hunt Generator

Teacher Notes

A. Prior to the lesson:

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

• Download a QR reader (e.g. I-Nigma | NeoReader | Kaywa) onto their mobile devices
• Bring these devices into the lesson.

3. Print out the QR codes.

4. Cut them out and place them around your class / school.

---

B. The lesson:

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!

Questions / Answers (teacher reference)

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
