online as well.
I'll admit that I don't know anything about the episodes. (Which is no doubt leading you to wonder what I'm doing talking about this).
What I do know is that regardless of whether or not you use the episodes, there are some great activities that accompany (but don't require) the episodes available for you to use with your class. You can find them in a couple of ways...
...if you go to the episode & guides section, you can print out the complete guide for each Sci File.
...or you can go to the educator's section of the old(er) website and find individual activities and worksheets.
Some of the 20+ Sci File titles include:
--The Case of the Wacky Water Cycle
--The Case of the Shaky Quake
--The Case of the Disappearing Dirt
--The Case of the Prize Winning Plants
I printed out complete guides of the Sci Files I was most interested in (and thought I would get the most use out of), because the site hasn't been updated since 2007. It's still there for now, and maybe it will be forever, but it's something to keep in mind.
