Solar System Unit

1. Solar System Unit By: Brianna Shields January 3, 2005

2. DO NOW • 1. What planet do we live on? • 2. What is at the center of our solar system? • 3. How many planets are there?

3. GOAL • To be able to explain the universe in terms of stars, planets and moons relative to our solar system

4. Solar System Objects travel around/ orbit the sun Held in by sun’s gravity Objects in the Solar System

5. 9 planets Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune Pluto Objects in the Solar System My very educated mother just served us nine pizzas

6. Asteroids Huge Strangely shaped Rock or metal Objects in the Solar System

7. Asteroid Belt Area of asteroids between Mars and Jupiter Objects in the Solar System

8. Moons Satellites or small rock orbiting a planet Objects in the Solar System

9. Comet Chunks of rock, dust, ice Dirty snowballs Long, flat oval orbits Halley’s Comet- 76 yrs to orbit sun Objects in the Solar System

10. Meteoroids Small bits of rock in space Objects in the Solar System

11. Meteors A meteoroid that has entered earth’s atmosphere Begins to burn Shooting star Objects in the Solar System

12. Meteorite Meteor that reaches earth’s surface Objects in the Solar System

13. Explain how the orbits of the planets are shaped. What object do they all orbit around? Assessment

14. Compare and contrast meteors, meteorites and meteoroids. Which is pictured here? Explain Assessment

15. Compare and contrast asteroids, meteoroids and comets Which is pictured here? Explain Assessment

16. Describe how to tell whether something can be considered a moon Assessment

17. Critique this picture and the man’s statement: “This here meteoroid done fell outta tha sky. Almost done bopped me in my head!” Assessment

18. Inner Planets Rocky surfaces (mountains and craters) Metal cores No rings No or few moons Smaller sizes Warmer (closer to sun) The Nine Planets

19. Inner Planets 1. MERCURY Fastest revolution Slow rotation The Nine Planets

20. Inner Planets 2. Venus Thick acid clouds trap heat (greenhouse effect) Retrograde rotation (opposite) The Nine Planets

21. Inner Planets 3. Earth Liquid water Life One moon The Nine Planets

22. Inner Planets 4. Mars Pink sky Icecaps Rust color Volcanoes & channels The Nine Planets

23. Outer Planets Colorful gaseous surfaces Giant sizes Many rings Many moons Cold temps (far from sun) The Nine Planets

24. Outer Planets 1. Jupiter Great red spot (wind storm) Giant liquid H ocean The Nine Planets

25. Outer Planets 2. Saturn Ice rings 20+ moons The Nine Planets

26. Outer Planets 3. Uranus Rotates on side Vertical ice rings Thick blue-green clouds The Nine Planets

27. Outer Planets 4. Neptune Blue color Cloudy Great dark spot Slushy surface The Nine Planets

28. Odd ball Planet 5. Pluto Double planet Small Hard surface Very cold The Nine Planets

29. Solar System Diagram • Look at the side board and copy the solar system diagram that Mrs. Shields is creating

30. Examine the photo at the left. Which planet is this? What evidence can you provide that supports this? Assessment

31. Examine the photo at the left. Which planet is this? What evidence can you provide that supports this? Assessment

32. Examine the photo at the left. Which planet is this? What evidence can you provide that supports this? Assessment

33. Compare and contrast the inner and outer planets. Assessment
