  1. Study Hall: Working Quietly In assigned seats.

  2. Unscramble these words below? 1. I am known as a ‘dirty snowball’ O T M C E R A T E H 2. I am the 3rd planet from the sun 3. I am now considered a dwarf planet L T O P U N U A T R T O S A 4. I like my space. I R A N M A O O L S T C T U I N 5. Earth’s average distance from the sun

  3. How did you do? Volunteers…. COMET 1. I am known as a ‘dirty snowball’ EARTH 2. I am the 3rd planet from the sun PLUTO 3. I am now considered a dwarf planet ASTRONAUT 4. I like my space. 5. Earth’s average distance from the sun ASTRONOMICAL UNIT

  4. WRITE IN NOTEBOOK Asteroids: chunks of rock left over from when the planets formed Largest of the solar system bodies Most common in the ASTEROID BELT (located between the orbits of Mars and Jupiter)

  5. ASTEROIDS

  6. What if an Asteroid struck the Earth? Discovery Channel Video of impact simulation http://www.youtube.com/watch?v=PENT_hnyO-o

  7. WRITE IN NOTEBOOK Comets: asteroid-like objects covered in dust, ice, gases, and metals that develop a fuzzy, cloud-like shell called a coma when they orbit close to the sun, the ice instantly melts, creating a long, visible tail (a dirty snowball) Form far away from the Sun

  8. HALEYS COMET

  9. Halley’s Comet Explanation of Halley’s Comet http://www.youtube.com/watch?v=oBq3-ZqW4Ac

  10. WRITE IN NOTEBOOK Meteoroid: Large pieces broken off from an asteroid or comet

  11. WRITE IN NOTEBOOK Meteor: A meteoroid that burns up in the Earth’s atmosphere. Creates a flash of light = ‘shooting stars’ Smallest of the solar system bodies

  12. WRITE IN NOTEBOOK Meteorite: A meteoroid that does not burn up in the Earth’s atmosphere It lands and crashes onto the Earth.

  13. Barringer Crater created 50,000 years ago Hole created when massive meteorite struck Arizona

  14. Meteorite Hitting Earth http://www.youtube.com/watch?v=dpmXyJrs7iU VIDEO IN RUSSIA

  15. Homework: “I am” Activity Directions: Each statement gives you a hint for which one it is. The words can be used more than once. Use your notes to help you fill in the blanks Due Tuesday in class

  16. Think about this…. How can Earth Sustain Life? 3 main reasons….

  17. WRITE IN NOTEBOOK 1. Distance from the Sun Sun = major source of heat and light for entire solar system Earth = formed in right location = just enough solar radiation = not too hot or too cold, moderate temperatures

  18. Discovery Ed. Video Earth Gravity’s effect on Planets Atmosphere

  19. WRITE IN NOTEBOOK 2. Earth’s atmosphere Blanket of gases surrounding Earth Protects humans from harmful radiation It is breathable Made of: nitrogen (78 %), oxygen (21%), and 1 % inert gases (argon, carbon dioxide, water vapor)

  20. Video on layers of the Atmosphere http://www.youtube.com/watch?v=WaikvaAw2nk

  21. Picture of the atmosphere

  22. WRITE IN NOTEBOOK 5 Atmospheric Layers: Troposphere: closest to the ground, where all weather happens (clouds found here) Stratosphere: ozone layer, where airplanes fly Mesosphere: where meteors/rock fragments burn up Thermosphere: where northern lights ‘Auroras’ occur Exosphere: where spacecraft/satellites orbit, upper limit of Earth’s atmosphere

  23. WRITE IN NOTEBOOK 3. Earth contains liquid water Only planet in solar system to contain liquid water Liquid water is essential for life to exist If we were closer to the sun, our oceans would boil away while if we were farther away, our oceans would freeze

  24. Discovery Ed: READING ACTIVITY • Read the article – Class set • Answer the questions in your notebook with your table partner • Answers need to be written in COMPLETE sentences for ANY credit. • 

  25. Solar System Worksheet Complete this if not done earlier Add distance (AU) for each planet

  26. Review Solar System Worksheet Follow along as I project the information onto the whiteboard

  27. Video “Why Mars Died and Earth Lived” http://www.youtube.com/watch?v=oC31pqk9sak
