  1. Scale the Universe Exploring your Universe from Inner to Outer Space Presented by: Fill in your name here

  2. The NASA Educator Ambassador Program at SSU You should modify this slide to fit you Swift GLAST XMM-Newton

  3. What is GLAST? • GLAST: Gamma-Ray Large Area Space Telescope • Planned for launch in 2007 • GLAST has two instruments: • Large Area Telescope (LAT) • GLAST Burst Monitor (GBM) • GLAST will look at many different objects within the energy range of 10keV to 300GeV. LAT GBM

  4. What is GLAST? • 1st ever collaboration between the BIG (Astrophysics) and the small (Particle Physicists) • NASA & DOE • By studying the largest most energetic things in the Universe (GRB’s), answers to the smallest subatomic particle/energy relationships are hoped for. LAT GBM

  5. What is GLAST? • 1st ever pair conversion telescope • Gamma rays are produced in the annihilation of electron-positron pairs as dictated by relativity. • The GBM operated on a backwards principle; • Turns gamma rays into electron-positron pairs that CAN be traced. LAT GBM

  6. EM Spectrum • Seven volunteers • Place the EM Spectrum stickers in order from smallest to largest wavelength • Review order and include specific sizes.

  7. Smallest to Largest • Name the smallest things that you can think of… • What are some of the largest things you can think of? • What about the most distant object?

  8. Distance Tabs • On your desk there should be one or more pieces of paper with masking tape on them. • In groups - place these in order on the using left to right as small to large • Small on left, large on right

  9. Distance Tabs • As with the EM Spectrum stickers... • One group places their list on the wall by the EM stickers. • Report and record • Each group reviews and edits • Another group edits the 1st group’s order • Discussion & review

  10. Well Known Objects… • What was the most interesting thing that you found while lining up the distance tabs? • Going back to our original list of small and large objects… • Is there anything on this list that wasn’t mentioned in the tabs?

  11. Well Known Objects… • Now, volunteer combines the EM stickers with the Ordering Distance stickers by placing each EM in the appropriate place. • Any surprises?

  12. Ordering Distance Objects “Average Virus” 7.5x10-8 m

  13. Ordering Distance Objects Width of DNA Helix 2x10-9 m

  14. Ordering Distance Objects Height of “Average” Human 1.7x100 m

  15. Ordering Distance Objects Mount Everest (http://peace.sandiego.edu/images/programs/Mount%20Everest.jpg) 8.85x103 m

  16. Ordering Distance Objects Moon Radius (www.noao.edu/image_gallery/ images/d4/moon.jpg) 1.74x106 m

  17. Ordering Distance Objects Moon’s Orbital Radius & Sun 3.84x108 m

  18. Ordering Distance Objects Earth Orbital Radius 1.5x1011 m

  19. Ordering Distance Objects Pluto Orbital Radius 5.9x1012 m

  20. Ordering Distance Objects HD70642 (APOD 07/09/03) 9.4x1017 m

  21. Ordering Distance Objects Crab Pulsar 7x1019 m

  22. Ordering Distance Objects Radius Milky Way (APOD 09/08/95) 5x1020 m

  23. Ordering Distance Objects LCM – Large Magellanic Cloud (APOD 02/22/00) 1.8x1021 m

  24. Ordering Distance Objects Andromeda (APOD 03/14/04) 2.9x1022 m

  25. Ordering Distance Objects AGN 3C 273 7x1025 m

  26. Ordering Distance Objects GRB990123 (APOD 01/29/99) 1x1026 m

  27. Earth and Moon System • At your desk there should be precut moon rulers. • Assemble them with the tape located on the tables. • Using the moon rulers answer the questions on the two activity sheets. • NOTE: For the second activity substitute the moon ball (golf ball) for the paper plate.

  28. The Universe is a VERY Big Place At least 13 billion light-years (or about 100,000,000,000,000,000,000,000 kilometers) It is full of VERY big numbers! And small!

  29. Scientific Notation and tens 10000 = 1x 104 1000= 1x 103 100 = 1x 102 10 = 1x 101 1 = 1x 100 0.1 = 1x 10-1 0.01 = 1x 10-2 0.001 = 1x 10-3 0.0001 = 1x 10-4

  30. How this works:

  31. The Booklet • This book is organized into 3-stand-alone sections: • A: • A1: Orders of Magnitude • A2: Unit Analysis • B: • B1: Ordering Distance – Sticky (what we just did!) and Cutout • B2: Using a Log Scale • C: • C1: Scale the Universe (1) • C2: Scale the Universe (2) • C3: Scale the Universe (3) • C4: Proportional Thinking • C5: Ordering Time (Next, time permitting!)

  32. The Booklet • Repeat the steps of the “Ordering Distance” activity • Place in order from short to long duration • One group reports • Discuss and review

  33. Brainstorm Time • How can we use this in our science classroom? • Biology Lessons • Astronomy Lessons • Physics Lessons • Introductions and applications of scientific notation • ….
