What is GLAST/Fermi?
• GLAST: Gamma-Ray Large Area Space Telescope
• Launched in 2008 (watch launch)• Fermi has two instruments:
– Large Area Telescope (LAT)– Gamma ray Burst Monitor
(GBM)• Fermi looks at many different
objects within the energy range of 10keV to 300GeV.

Who is GLAST/Fermi?
• A collaboration between the BIG (Astrophysics) and the small (Particle Physicists)
• By studying the largest most energetic things in the Universe (GRB’s), answers to the smallest subatomic particle/energy relationships are hoped for.

What is GLAST/Fermi?
• 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.
GBM

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

Exponential Clothesline
• Place the numbers on the clothes line as indicated by the facilitator.
• Lowest on the left, highest on the right.

Exponential Clothesline
Many students have difficulty expressing large numbers using exponential notation. The exponential clothesline helps to pre-assess student understanding of exponents by providing a visual representation of exponential notation (powers of ten). Materials:One 5-meter piece of clothesline (or string) Fourteen (14) clothespins (or paper clips) Fourteen (14) index cards with the following numbers: 0 written in red 1, 2, and 3, in blue 101, 102, 103, 106, 109, and 1012 in green (Or more numbers10-1, 10-2, 10-3, and 10-4 in black to make class set)Depending on your group, you may wish to provide some larger (or smaller) exponents or include a set of numbers with exponents such as 2 x 100, 2 x 101, 2 x 102 and 2 x 10-2.See my webpage for full instructions www.fermiepo.wikispaces.com

Graphing…
• How could we plot all these distances/sizes on the same scale?– If you used a detailed enough scale to show
the small objects, your graph would go far into outer space.
– If you used a large enough scale to fit all the larger distances, the small objects would pile on top of each other at zero.
![Page 41: “Scale the Universe” Exploring your Universe from Inner to Outer Space Presented by: Teena Della NASA’s Educator Ambassador Teacher at Riverside Secondary.](https://reader034.fdocuments.us/reader034/viewer/2022051315/56649ef45503460f94c074f7/html5/thumbnails/41.jpg)
Graphing…
Solution:
Use a logarithmic scale…

• Log Scale Activity– Cut out and paste the Distance Tabs onto the
Log Scale (pg 14 in Tops Guide)– We won’t do this activity today, but it is there
for you in the activity book – with answer keys…

Brainstorm Time
• How can we use this in our specific classrooms?
• Where would scientific notation be useful?• Where would logarithms be useful?• How can we adapt for different ability
levels? Or different learning needs?
