Serves to demonstrate Boyle's Law. Shows what happens when gases are subjected to increased pressure. The plastic syringe, with solid wood base and platen, is constructed so that the calibrations denoting interior volume read right side up. As masses of bricks, books, or other heavy objects are increased, the gas in the syringe is compressed to smaller and smaller volume. The kit includes: 1 Syringe Cylinder w/ Cap, 1 Syringe Piston, 1 Base, 1 Platen.

Introduce your students to the fundamentals of chemistry. Provide your class with a basic understanding of the primary concepts of chemistry as they investigate how matter is classified, identify the various types of mixtures, and compare the properties of solutions with the properties for mixtures. They'll also learn to identify elements and compounds and study how chemical symbols, formulas and equations are used to describe chemical reactions. Grades 7-10.
By touching two metal strips simultaneously your body becomes a path for charged molecules to complete a circuit. Result: the ball glows brightly. Works with several people creating the path. When opened, the energy ball reveals a working circuit for insight into the world of computers.
