Since you asked...

A Summer Challenge >>> Some of you were interested in actually sending your own radio signals - I have no idea how -- but here are some sites that give instructions, and of course you can google your own:

http://www.instructables.com/id/Make-Your-Own-Low-Power-AM-Radio-Transmitter/?ALLSTEPS

Either of these directions involves buying several parts, an oscillator and a transistor and a board.  Let me know if you get it going.  And have a wonderful summer.

OR: how about a solar powered electromagnetic pendulum - the best of all possible combos!  http://makezine.com/2010/06/02/beautiful-solar-pendulum-build/

More Electromagnetic Induction!

The Electromagnetic Spectrum: Galactic Space

Light in Slow Motion (Remember in our textbook, it said that light is both a particle and a wave- if you watch the pulse of light in the Coke bottle, you can visualize how this is so.  See it as a particle, a pulse, and then see it as a wave.)

Fun stuff..

Just for fun...

2.  And here's the real homework -->>>
3. Now for some radio parts-   No need to take notes; just listen and watch.

There you go!  See you Thursday.
