After realizing that, I've been looking for ways to incorporate internet resources into my teaching, and trying to find cool citizen science projects, activities, and simulations that would be appropriate for a grade school science class, such as galaxyzoo and fold.it. So, I'm asking slashdot for more resources that could help bring science to their lives. Thanks!"

Hahaha... do you really thing a teacher's day end when the last bell rings? Or that many teach summer school just to make ends meet?
Not to mention that teachers pay increases have outstripped inflation consistently
This doesn't seem to apply for any teacher I know.

Hey! I'm just going through a teacher's program right now, and I've been looking for resources to use with smartboard. First of all, if you don't have a smartboard go here:

Then try out:
Algodoo (costs about 25 euros): Great physics simulator. I would say it would be useful even for university students. You can, however, adjust the difficulty level. It's good for kinematics, some optics, buoyancy, some fluid dynamics and a few other things. I started off with making a piston pump system.

Crayon physics: Great for intuitively exploring some physics concepts. It costs about 20 bucks. It's similar to above but it's closer to a game. There are a series of challenges that you accomplish (try to move a ball to a star, overcoming a series of obstacles. Learn some physics concepts through osmosis.

Celestia: Great freeware for exploring our galaxy (and neighboring galaxies). It implements astronomy knowledge into a space simulator. It allows to you to visit out solar system and beyond. As humanity discovers more, you can update the planet (i.e. with new exoplanets). This one is super cool, a little like Eve Online but IRL. You can also install Star Trek universe updates if you are a trekkie, as well as Star Wars.

Ok that's the coolest stuff. There are other things out there but they aren't as impressive. ScaleoftheUniverse is neat, but limited in classroom utility: http://www.scaleoftheuniverse.com/ [scaleoftheuniverse.com]

These practical experiments will give the conceptual basis of what will be tested if the kids ever take an AP Science exam. They do not need to be fancy. Heat water measure rate of change. Build a gravity accelerated race track, film the cars, and analyze using free video analysis software. Run 1mw laser though pieces of plastic. And, the most important experiement of all, give them measuring instruments, let them measure things around the room, and then compare results. They will be amazed at how different everyone's mesasurements are. At that age, mean, mode, median, and rage are valid math concepts.
As far as online goes. Look for any and all animated experiments. PHET has many of them. You can download videos of experiments, or have the kids make them, and make scatter plots relating various variables using Tracker Video Analysis. The construction of these graphs meet many objects for high school math and science. I have found online sources to simulate any experiment that I want to do. Most of these are accesible to almost any age group by simply by adjusiting pre-lab instruction and post-lab assessment
Just like in any expeiment, the pre- and post-lab are the thing. Most kids will lean very little from a lab without a pre- and post-lab. Doing the lab is only going to be so successful. The required analysis of what the student has observed is a key learning process. In any lab, online or not, know the concepts that are to be taught, and how they will be reinforced and assesed. For instance on PHET you can make resistors catch fire. Why do they catch fire? Will they catch fire faster if the resistance is increased of the potential or current. This creates an exciting learning activity.

Stellarium and Skycharts (Cartes du Ceil) are among the best sky simulation and mapping software and well worth a look along with Stellarium. Or try Kstars on Linux

Much more. No time to post right now though.
