Learners investigate simple machines and their uses in everyday life.  In this scientific method instructional activity, students examine physical tools such as wedges, screws, and levers using a "how does it work" approach....

Fifth graders divide into teams and select a simple science topic to explain and illustrate. They should pick a topic that they can illustrate with a very short (about 15-20 seconds) video clip, or QuickTime movie.

Third graders explore how simple machines can affect their health and lifestyle. In addition, 3rd graders use their knowledge of simple machines to build a unique machine.
