  • 2. 2012 Spring Sky Watch Challenge• Week 2, Level 2 Challenge: Orion Nebula• http://www.youtube.com/watch?v=xy5bbw-wYJo• Reminder: Planet and Week 1 Challenge reports are due tomorrow!
  • 3. Test Info• 30 questions – 5 multiple choice – 5 modified true/false – if false, make it true – 5 fill-in-the-blank – 5 short answer – 5 matching • Describing moon phases/info – 5 drawing/labeling diagrams • Moon Phases – drawing you need to label • Draw and label solar eclipse – inc. umbra/penumbra • Draw and label a lunar eclipse – inc. umbra/penumbra • Draw the sun and 4 earth’s labeling spring, summer, fall, winter • Why are you more likely to see a lunar eclipse

  • 5. Sun-Earth-Moon System• Rotation and revolution• Days• Years• Months• Weeks
  • 6. Cram Review Guide – Page 173• History – Ptolemy – geocentrism (Earth-centered) – Copernicus – heliocentrism (Sun- centered) – Kepler (Brahe –data) – orbit of planets are elliptical – Galileo – used telescope: evidence for helio: sunspots, Venus has phases & Jupiter has moons go around it – Newton – how planets stay in orbit- gravity and inertia • Gravity – pulls objects to the sun • Inertia – keeps them moving in a straight line • Together – they keep planets in orbit around the Sun
  • 7. Sun-Earth-Moon• Rotation – spin on axis – day and night• Revolution – orbit – years• Month – moon’s revolution• Weeks – 5 planets, moon & sun
