1. Scale the Universe Exploring your Universe from Inner to Outer Space Presented by: Sarah Silva and Phil Plait NASA Education and Public Outreach Sonoma State University

2. 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

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. 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?

5. 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.

6. 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?

7. 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.

8. 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!

9. Scientific Notation and tens 10000 = 1x 10 4 1000= 1x 10 3 100 = 1x 10 2 10 = 1x 10 1 1 = 1x 10 0 0.1 = 1x 10 -1 0.01 = 1x 10 -2 0.001 = 1x 10 -3 0.0001 = 1x 10 -4

10. How this works:

11. 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

12. Brainstorm Time How can we use this in our science classroom? –Biology Lessons –Astronomy Lessons –Introductions to scientific notation –….
