With the items in the comprehensive Electrostatic Materials Kit, students learn about the frictional charging process by doing.
- Topics Include Polarity and Detecting Charges
- Students Create and Dissipate Static Charges
- Friction Rods
- Pith Balls
They can try all sorts of friction rods and natural materials to create and dissipate static charges.
Students can even use pith balls to detect charges and stirrups to dangle rods and reveal polarity.
Rods - Glass, Hard Rubber, PVC (grey tube), Polystyrene
Pads - Wool, "Fur" (acrylic), "Silk" (rayon)
