The Session 1 Advanced Technology Seminar, an 22nd, was very helpful. I learned what a BLOG is, how to set one up, and to manipulate it (up to a point) Practice will greatly improve using and forming better BLOGS.
The following are ideas I will look into in using BLOGS at Bonny Eagle HS.
1) Develop BLOG to communicate with students.
2) Develop BLOGs in conjunction with PortaPortal in setting up lesson plans.
3) Develp Home Work and Study Sheet BLOGS.

Aristotle - Newton
Aristotle - Fire, Air, Earth, water: All things have their natural place in the universe. My task is to learn, and teach where these natural places are. The earth is the center (Geocentric System) of all things (the universe)
Galileo - The Sun is the center of the Universe with the earth, satellites, and planets revolving concentrically about it. (Heliocentric System) My job is to describe the true motions of the heavens and bring truth to the world through experimentation, and observation.

Einstein The Theory Behind the Equation
by Michio Kaku
Einstein's Big Idea homepage
Imagine a police officer chasing after a speeding motorist. If he drives fast enough, the officer knows that he can catch the motorist. Anyone who has ever gotten a ticket for speeding knows that. But if we now replace the speeding motorist with a light beam, and an observer witnesses the whole thing, then the observer concludes that the officer is speeding just behind the light beam, traveling almost as fast as light. We are confident that the officer knows he is traveling neck and neck with the light beam.
But later, when we interview him, we hear a strange tale. He claims that instead of riding alongside the light beam as we just witnessed, it sped away from him, leaving him in the dust. He says that no matter how much he gunned his engines, the light beam sped away at precisely the same velocity. In fact, he swears that he could not even make a dent in catching up to the light beam. No matter how fast he traveled, the light beam traveled away from him at the speed of light, as if he were stationary instead of speeding in a police car.
But when you insist that you saw the police officer speeding neck and neck with the light beam, within a hairsbreadth of catching up to it, he says you are crazy; he never even got close. To Einstein, this was the central, nagging mystery: How was it possible for two people to see the same event in such totally different ways? If the speed of light was really a constant of nature, then how could a witness claim that the officer was neck and neck with the light beam, yet the officer swears that he never even got close?
Einstein had realized earlier that the Newtonian picture (where velocities can be added and subtracted) and the Maxwellian picture (where the speed of light was constant) were in total contradiction. Newtonian theory was a self-contained system, resting on a few assumptions. If only one of these assumptions were changed, it would unravel the entire theory in the same way that a loose thread can unravel a sweater. That thread would be Einstein's daydream of racing a light beam.
