Everyday, we repeatedly use simple machines to accomplish necessary tasks. This solid program clearly explains what simple machines are and how they work, before demonstrating each of the six types: levers, inclined planes, wedges, screws, wheel and axles, and pulleys. A number of practical applications are shown (thus negating any of those “what does this have to do with real life?” questions), and the program features great visuals and computer animation to help explain the concepts. The next time you un(screw) a jar of peanut butter and use a knife (lever) to move some to your bread, you'll know that you are using simple machine principles to create a sandwich. In addition to a teacher's guide and accompanying curriculum, the DVD also includes extras such as labeled slides, a glossary, and an iMovie project. Recommended. Aud: E, I. (E. Gieschen)
