Students examine the parts of a lever system and their functions.  In this simple machines lesson students study the different classes of levers and what they are used for. 

Students compare and contrast the three different types of levers. In this physics instructional activity, students hypothesize how ancient Egyptians use them to build structures. They construct their own lever after teacher approves...

Seventh graders identify the different parts of a lever. In this physics lesson, 7th graders draw a lever and label the different parts. They use the interactive board to create their own lever.

Students explore electromagnetism, simple machines and the design process. They use the concepts of electromagnetism to design and build a device that uses an electromagnet, a pulley and a lever using the provided Engineering Design...

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.
