Scale the Universe Exploring your Universe from Inner to Outer Space Presented by: Sarah Silva and Phil PlaitNASA Education and Public Outreach Sonoma State University
The NASA E/PO Program at Sonoma State University • A group of eight people working collaboratively to educate the public about current and future NASA high energy astrophysics/astronomy missions. • Led by Prof. Lynn Cominsky 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
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 brown paper. • The left hand side of the paper should have the small scale items and the right hand side of the paper should have the large scale items.
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?
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
Brainstorm Time • How can we use this in our science classroom? • Biology Lessons • Astronomy Lessons • Introductions to scientific notation • ….
