The Precision Linear Expansion Apparatus produces accurate determinations of the coefficient of expansion.

Electrostatic charges are indicated by the deflection of a black plastic straw pivoted on a pin. The polished zinc plate on top is used to demonstrate photoelectric effect and various other electrostatic demonstrations. The metal case measures 14 cm in diameter. The scale is graduated in 10° increments in two quadrants.

Enough materials for a complete class to perform all of the electrostatics experiments included in this set.

Grab and hold students' attention with these interactive and affordable demonstrations that show core physics concepts in action.

Appropriate for grades 6 to 12 Brings the First Law of Thermodynamics to life! This pair of precision-machined, chrome-plated steel balls is actually a hands-on demonstration in energy transformation. By striking the balls together, you will create enough heat at the point of contact to burn a hole in a sheet of paper.

Perfect for any style alcohol lamp, this stand can be used in two different height levels (9 or 13 cm) by simply removing the wire gauze top, turning the stand on its side, and putting the top back on. It is constructed of stainless steel rod with an 8 x 10 cm wire gauze surface. The edges of the wire gauze are turned under for safety.
