Make your work as a teacher a little easier with a physical science project on simple machines. After introducing young scientists to these devices and identifying their different uses around the school, this project engages...

The choice is simple: create a PowerPoint presentation, write a book, or invent a compound machine. Whichever project your young scientists choose, they will be engaged in creatively demonstrating their knowledge of simple...

How many of your pupils play an instrument? A musical science lesson will help all of them understand how string instruments work. Young scientists construct a string-and-pulley system to test frequency and pitch. The lesson...

Class members are challenged to design a device that will move a circus elephant into a train car. Groups brainstorm ideas that use simple machines to load the elephant. They then choose one of their ideas, sketch a plan, and present it...

A collection of simulations representing concepts discussed in a mechanics unit of physics.

This site provides an easy to understand experiment that will demonstrate the pulley to students in grades K-3. It requires only everyday materials. The students are encouraged to discover some of these concepts for themselves and apply...
