  2. Units of Measure $100 An Astronomical Unit (AU) is a measure of the average distance between these two objects.

  3. Units of Measure $100ANSWER The earth and the sun.

  4. Units of Measure $200 The distance that light travels in one year is known as this.

  5. Units of Measure $200ANSWER A light year

  6. Units of Measure $300 This is the most appropriate unit of measure to measure the distance between galaxies.

  7. Units of Measure $300ANSWER Light years

  8. Units of Measure $400 This describes how you know when to use light years and AUs.

  9. Units of Measure $400ANSWER Star distances: Light years Planetary distance: AUs

  10. Units of Measure $500 Mars is approximately 2 AU from the sun. If it takes sunlight 10 minutes to reach Earth, this is how long it takes sunlight to reach Mars.

  11. Units of Measure $500ANSWER 20 minutes

  12. A little bit of Everything $100 This is the phenomenon responsible for the shape of planets, stars, and the orbit of the planets.

  13. A little bit of Everything $100ANSWER Gravity

  14. A little bit of Everything $200 This is an icy object orbiting the sun in a highly elliptical path.

  15. A little bit of Everything $200ANSWER Comet

  16. A little bit of Everything $300 This is used to classify stars according to their size and luminosity.

  17. A little bit of Everything $300ANSWER H-R Diagram

  18. A little bit of Everything $400 Solar and lunar eclipses both are seen because of shadows. What causes the shadows?

  19. A little bit of Everything $400ANSWER An exact straight line between the Earth, Moon, and Sun

  20. A little bit of Everything $500 This describes the order of Earth, the Moon, and the Sun during: • Lunar Eclipse • Solar Eclipse

  21. A little bit of Everything $500ANSWER • Lunar: Moon, Earth, Sun • Solar: Earth, Moon, Sun

  22. 8 great planets $100 These are the 4 inner planets.

  23. 8 great planets $100ANSWER Mercury, Venus, Earth, & Mars

  24. 8 great planets $200 These are the 4 outer planets.

  25. 8 great planets $200ANSWER Jupiter, Saturn, Uranus, Neptune

  26. 8 great planets $300 A new planet is found in our solar system. It is large and is composed of many gases. You would expect this new planet to be located here.

  27. 8 great planets $300ANSWER Near the rest of the outer planets.

  28. 8 great planets $400 This is what physically separates the inner planets from the outer planets.

  29. 8 great planets $400ANSWER Kuiper Belt (asteroids)

  30. 8 great planets $500 This describes how inner and outer planets differ.

  31. 8 great planets $500ANSWER Inner: smaller, rocky Outer: larger, gaseous

  32. Shining Stars $100 This is where nuclear fusion occurs to produce a star’s light.

  33. Shining Stars $100ANSWER The core

  34. Shining Stars $200 Almost everything in the universe shines by reflecting light. These are the only things that produce light.

  35. Shining Stars $200ANSWER Stars

  36. Shining Stars $300 This describes how to determine the gases in a newly detected star.

  37. Shining Stars $300ANSWER Use a spectroscope to look at the light from the star. The absorption spectrum will tell what elements are present.

  38. Shining Stars $400 This is the list of star colors from coolest to hottest.

  39. Shining Stars $400ANSWER Red, yellow, white, blue

  40. Shining Stars $500 This is the correct star type for a newly discovered star with a diameter of 25 compared to our sun.

  41. Shining Stars $500ANSWER Red Giant

  42. Galaxies galore $100 A grouping of stars, gas, and dust held together by gravity.

  43. Galaxies galore $100ANSWER A galaxy

  44. Galaxies galore $200 This is the approximate number of stars in each galaxy.

  45. Galaxies galore $200ANSWER Billions

  46. Galaxies galore $300 This type of galaxy

  47. Galaxies galore $300ANSWER Spiral galaxy

  48. Galaxies galore $400 Compare and contrast elliptical galaxies and spiral galaxies.

  49. Galaxies galore $400ANSWER • Elliptical: oval shape, old red stars, can be flat or have bulge • Spiral: have spiral arms, young blue stars, flat with a bulge • Both: galaxies, billions of stars

  50. Galaxies galore $500 This explains why we cannot see the spiral shape of the Milky Way Galaxy.
