  1. Warm Up – Then Complete Reflection What is the difference between Rotation & Revolution? How does the sun produce energy? What is the name of the telescope that showed us the Universe is still expanding? What is Kepler’s 2nd law? How are you feeling about today’s exam??

  2. WE ARE MOTIVATED BY OUR GOALS! Objective Agenda Warm Up Objective Independent Review Unit 2 Assessment Vocabulary Search • SWBAT show progress towards 85% mastery on Astronomy content. • Homework: Booklet Due TODAY

  3. Warm Up – Then Complete Reflection What is the difference between Rotation & Revolution? How does the sun produce energy? What is the name of the telescope that showed us the Universe is still expanding? What is Kepler’s 2nd law? How are you feeling about today’s exam??

  4. Explain the significant difference between Rotation & Revolution. What is the relationship between these terms?

  5. Explain the significant difference between Rotation & Revolution. What is the relationship between these terms? Rotation = Day & Night = 24 hours duration Revolution = 1 Year = 365.25 Days

  6. How does the sun produce energy? Be specific! How does it travel to earth? The Sun produces energy through an energy reaction called Nuclear Fusion, which 2 Hydrogen fuse to make 1 Helium which produces energy. It travels via Radiation

  7. What is the name of the telescope that showed us the Universe is still expanding? Hubble

  8. Kepler’s Law that states when planets orbit they cover equal amounts of time Second

  9. Update • Unit 2 Exam =16multiple choice • Unit 2 Exam = 3 short answer =4points • Unit 2 Exam = 20 points

  10. Transition to Independent Review • I will give you 4 minsto get materials & transition • Assigned seats ONLY • Headphones may be rewarded for productive behavior after 5 mins of work • I will tell you, please don’t ask

  11. Independent Review • During this time, you need to: • Stay Seated in Assigned Seat • Talk quietly • Raise hand to ask questions • Feel confident for this test • If you finish early, • Crossword • No copying, both parties will be penalized • Late Work (Labs) • Crib Sheet (1/2 paper, 1 side only)

  12. Independent Review • During this time, you need to: • Stay Seated in Assigned Seat • Talk quietly • Raise hand to ask questions • Feel confident for this test • If you finish early, • Crossword • No copying, both parties will be penalized • Late Work (Labs) • Crib Sheet (1/2 paper, 1 side only)

  13. Unit 2 Assessment • When finished with the assessment • Hand it in • Get vocabulary sheet & textbook • Sit down • Work quietly on vocabulary for next unit • If you are missing work, now is the opportunity to work on it • No talking until everyone is finished!

  14. What protects Earth from dangerous solar winds, solar radiation, cosmic rays, X rays and some electromagnetic waves? The Earth’s Magnetic Field protects us from solar winds The Earth’s Atmosphere protects us from Cosmic & X Rays Don’t worry about solar radiation & electromagnetic waves.

  15. Compare and contrast the meaning of Equinox and Solstice. Summer Solstice: Day of most sunlight June 21st Winter Solstice: Day of least sunlight December 21st Spring Equinox: Day of equal amount of night & day (12hrs of each) March 21st Fall Equinox: Day of equal amount of night & day (12hrs of each) September 23rd

  16. Explain what causes seasons on Earth. Incorporate how the northern and southern hemispheres are affected differently by seasons. The Earth’s TILTcauses seasons Northern & Southern hemispheres experience opposite seasons Summer in North then Winter in South

  17. Is Earth’s orbit a perfect circle? Explain why or why not with scientific reasoning. No- Earth’s orbit is an ellipse (aka oval) Johannes Kepler’s 1st law of planetary motion states this, while his 2nd and 3rd laws mathematically prove his 1st

  18. By incorporating the Big Bang Theory explain the hierarchy of the universe. Give 2 examples. The hierarchy of the universe: The universe is made up of many different structures arranged in a fairly well-defined hierarchy.

  19. By incorporating the Big Bang Theory explain the hierarchy of the universe. Give 2 examples. Made first = biggest Made last = smallest

  20. Crossword I am picking some particular ones to go over.

  21. 15 Across: The process which solar energy is converted into chemical energy I am picking some particular ones to go over.

  22. 15 Across: The process which solar energy is converted into chemical energy Photosynthesis

  23. 17 Across: The type of energy we receive from the sun I am picking some particular ones to go over.

  24. 17 Across: The type of energy we receive from the sun Radiation

  25. 21 Across: The northern hemisphere & southern hemisphere always have_______ seasons

  26. 21 Across: The northern hemisphere & southern hemisphere always have_______ seasons Opposite

  27. 22 Across: High Tides are caused by the Moon’s ______

  28. 22 Across: High Tides are caused by the Moon’s ______ Gravity

  29. 3 Down: The Center of mass between two objects orbiting each other

  30. 3 Down: The Center of mass between two objects orbiting each other Barycenter

  31. 5 Down: The Wobble within the wobble of earth’s rotation

  32. 5 Down: The Wobble within the wobble of earth’s rotation Nutation

  33. 9 Down: Hydrogen reactions give off lots of energy in the form of heat & light Nuclear Fusion

  34. 16 Down: This telescope showed us Earth (should say Universe) is still expanding

  35. 20 Down: Kepler’s Law that states when planets orbit they cover equal amounts of time

  36. 20 Down: Kepler’s Law that states when planets orbit they cover equal amounts of time Second

  37. Take a minute & check your other answers
