Materials for demonstrating the generation of electrostatic charges with friction rod . a hollow glass rods Kit includes solid glass rod and a wool friction hard rubber rod, silk friction pad, pad, flannel friction pad, animal fur( synthetic) friction pad, 3 balloons, 10 ft of string and instructions. Grades 9+
Demonstrates conversion of kinetic energy into heat and sound energy during a collision. Consists of a pair of heavy steel balls. When the balls strike against each other with a piece of paper between the balls, the heat causes a hole to appear in the paper. The kinetic energy of the balls upon collision is converted to heat which is…
To demonstrate the inverse relationship between density and length. The specimens, Aluminum, Copper, Nylon, Polyvinylchloride and Polyethylene, are all 12 mm in diameter with 15 gm mass. Length range from 15 to 100 mm. Instructions are included.
To demonstrate the conversion of mechanical energy into electrical energy. A copper disc with a turning handle rotates between two poles of a horseshoe magnet. On base with two terminals, one of which is connected to a pillar supporting the disc and the other to a brush bearing on edge of the disc.
Learn about magnetic fields with our Floating Magnet Set. The three ring magnets are incased in plastic and each pole is marked as N/S. They are also color coded for quick visual identification. Comes with it's own stand. 1.5 X 1.5 X 5.5”. Ages 7+
