Scale the Universe Exploring your Universe from Inner to Outer Space Presented by: Fill in your name here
The NASA Educator Ambassador Program at SSU You should modify this slide to fit you Swift GLAST XMM-Newton
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
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
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
EM Spectrum • Seven volunteers • Place the EM Spectrum stickers in order from smallest to largest wavelength • Review order and include specific sizes.
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?
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
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
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?
Well Known Objects… • Now, volunteer combines the EM stickers with the Ordering Distance stickers by placing each EM in the appropriate place. • Any surprises?

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.
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!
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
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!)
The Booklet • Repeat the steps of the “Ordering Distance” activity • Place in order from short to long duration • One group reports • Discuss and review
Brainstorm Time • How can we use this in our science classroom? • Biology Lessons • Astronomy Lessons • Physics Lessons • Introductions and applications of scientific notation • ….
