Since I've got this fabulous technology available, I've been spicing up my lessons with visual material on a regular basis. I'd like to do this at least twice a week--it could be a short, 3-minute video, but the change in pace really perks the class up. And of course I find a way to tie it into my lesson.
Recently, for example, we were learning about the fifth day of creation, and I showed a two-minute video of a Patriot missile launch and interception, then contrasted this with a scorpion's ability to sense its prey and put itself into position to intercept it.
Another time we were discussing the development of matter into solid, liquids and gases, and I was able to use some flash material from Smartboard's Essential for Educators library to give it a little zing.
So now I'm searching for more material, and I find myself at a loss more often than not. I realize a large part of finding stuff is knowing what to look for, and it does take some original thinking on my part, but it would still be useful to have sources aside from YouTube and the Essential for Educator's gallery.
Are any of you using videos (or other visual material) in your lessons, and where do you find it?
