Interesting article about the status of Pluto - According to the I.A.U., Pluto is still not a planet, hence, we only have eight. What I found funny was the "No Planet Left Behind" theory, which would give us 13 planets in our solar systems. This generated a lot of discussion in the comment section as well.
New Year's brings a time to look back at the year and reflect - this resource is looking back on the top science events in 2008. It's no surprise that CERN's Large Hadron Collider tops the list.
This guy has posted a ton of screencast tutorial videos for math and physics. Chemistry teachers may want to reference these to help students with their basic skills.
Free textbooks online - I just took a quick look through, but they have bio, chem, physics, and biochem books for science. Scroll down on the page to find.
This page has a long listing of Wiki examples for all subject areas. There are a good number of science example. An easy way to find them is to Click on Edit->Find, type in Science, and keeping hitting enter (or find) to get through the page.
This has "science interactives", or virutal manipulatives that students can use. I've seen the roller coaster before, but I haven't seen the rest. Their new interactives include DNA, Periodic Table, Dynamic Earth, and the Rock Cycle.
This was posted to the Science Teachers group - For those that are not members, here you go! Great resources for chemistry related simulations - also contains some biology related chemical simulations as well (i.e. protein structure)
Library of math and science java applets. These let you set your own variables and conduct online lab / experimentations. Subject areas include bio, chem, physics, earth and space, and math.
This includes resources for Pre-K through 12 for all subject areas. You may want to take a look to see what is offered for science and upper grade levels.
