Fermi Launch June 11, 2008 (Click picture to view launch.)
The parts of Fermi Large Area Telescope (LAT) Gamma-Ray Burst Monitor (GBM)
Why multi-wavelength telescopes? The Milky Way • Visible • Infrared • X-Ray • Gamma-ray
Why multi-wavelength telescopes? Centaurus A:
What Fermi has been observing… • All sky survey • Thunderstorm emissions • Black holes, sucking in and spitting out • Subatomic particles at much higher energies than on Earth • Information about the birth and early evolution of the Universe • Gamma ray bursts, pulsars, supernova…
Newton’s Laws Song Time • “Laying Down the Laws of Motion” • A cute song about Newton’s 3 Laws of Motion • An alternative/fun way to present topics – students love music and remember lyrics • http://www.songramp.com/mod/mps/viewtrack.php?trackid=66355 lyrics next page
The physicist will not insist you learn the wizard's potion But minds will grow if students know of Newton's Laws of Motion Isaac Newton studied forces; forces make things start and stop Students taking science courses learn these laws to stay on top Things in motion stay in motion; things at rest will stay at rest. Inertia's our initial notion; know it and you'll pass the test. We're laying down the law; we're laying down the law; We're laying down the laws of motion. The next law's also worth a mention so wisdom will accelerate. Although I sense your apprehension, a speedy lesson is your fate. page 1 of 2
With your elbow, wrist and shoulder, here is how you must proceed Throw a ball and throw a boulder, greater mass means lesser speed. We're laying down the law; we're laying down the law; We're laying down the laws of motion. One last law we'll be explaining, says forces always come in pairs. Newton's law will leaving you straining when you're climbing up the stairs. Each step you take is called an action; push a wall, it pushes back When you act, expect reaction; equal and opposite, that's a fact. We're laying down the law; we're laying down the law; We're laying down the laws of motion.
Balloon races (3rd Law) • Using the strings with straws on them • Blow up a balloon of your choice – don’t tie it closed • Tape the straw on the string to the balloon • Once everyone is ready, we’ll count down and launch • The furthest balloon along the string is the winner of …
Fermi & Newton’s Laws of Motion 1st: When the rocket is on the launch pad, the forces acting upon it are balanced. 2nd: F=ma Force is the pressure exerted by the escaping gasses from the burning fuel. 3rd: The action is the expelling of the burning fuel out the back end, the reaction is the movement of the rocket into the sky. Gravity: Forward motion causes a circular orbit as the rocket constantly falls to Earth. Minimal friction.
Curricular activities to do with your classes: • Newton’s 3 Laws Lab – Grade 5, Physics 11 • Quadratics Lab – Math 11 • Estes SpaceLoft Lesson Guide • S4 Program (next slide)
Get involved in the Space Program! • http://s4.sonoma.edu/ • a partnership between the Education and Public Outreach group at Sonoma State University, Tripoli Rocketry Association’s AeroPac prefecture and the Endeavour Institute. • Through S4, educators can build experimental payloads to fly on tethered weather balloons and/or rockets, enabling students to participate in the thrill of experimental design and implementation. • Propose the project to your teacher!!
Now, build your own rocket to launch today! • The Firestreak SST can fly to about 350 feet, not super high, but good for a smaller launch area. • Other rockets, in many styles and skill levels, can be purchased at http://www.estesrockets.com/ • Follow the instructions to snap together your rocket. Decorate/re-enforce with stickers.
Launching Rockets: Safety Precautions • Never launch a damaged rocket. Repair first. • Choose a large field, 500 feet square; area should be free of dry grass, wires, trees, aircraft, buildings. • Launch with little or no wind. • Stand far back and monitor carefully so you don’t get hit. • Misfires: take the key out of controller and wait one minute before going near rocket to troubleshoot. Make sure igniter is touching propellant.
