OK... I KNOW this won't increase a test score, but this is a video of one of the most incredible homemade contraptions you'll ever see. The video itself is often a bit too dark to get a real good look at what's going on, but by the time it's over you, too, will be amazed at the ingenuity behind it.
http://snipurl.com/1gtqj (The url is WAYYY too long to post. If your school blocks these, that's OK. Send it home and watch it at home.)
Here's an idea... First, show this to your students. They'll get a kick out of it, I'm sure. Then, go back through and check off (from your handout) the different kinds of simple machines that these folks used in this contraption. OK... it was a reach... but really, you should see this video. It reminds me of this one from a while back: http://autorepair.about.com/cs/funstuff/l/bl_honda.htm That one had professional lighting and took a spooky 666 times before it went off perfectly.)
