Interesting article about the status of Pluto - According to the I.A.U., Pluto is still not a planet, hence, we only have eight.

Mr. Noon, a science teacher from upstate NY, has his classes online. Beware - this is a loud website. Watch the Flash animation in the PSP to get to the "Enter" button. He has some cool stuff for his classes and in general. This has resources for a lot of our sciences.
