An Essential Electrical part for use in physics, Electrical circuits, Sound experiments, and other general lab use. Strong plastic construction. The voltage requirement is 3 DC volts. Includes a 7/8" buzzer on a base with two holes for mounting and 3" L Connecting wires. Ages 7+
Electric calorimeters can be used with or without the electric heating element. With the heating element, students can determine the electrical equivalent of heat; without the heating element, it is a standard double-walled calorimeter. Instruction manual included. Ages 13+
Replacement electrodes for student Voltaic Cell set. Consists of 10 electrodes: 1 carbon, 1 nickel, 2 copper, 2 iron, and 2 zinc Electrodes are about 4 x 3/4".
2 wire coils on plastic spools. Straight iron core for bar magnet, 4cm long. U-shaped iron core for horseshoe magnet, 5 cm long. Lifting bar with hook, 2 compasses, 10 steel pins, 3 insulated wires with connecting tabs, Activity guide, and storage case.
This kit allows you to see the link between electricity and magnetism. Includes a copper wire coil, a “soft” iron core, a battery holder and two paper clips. Also comes with detailed instructions to guide you through the experiments on electromagnetic fields and polarity. Requires an AA battery. Ages 7+
This compact but powerful electromagnet lifts up to 200 lb using one D-cell battery (not included). Students learn why this magnet is so powerful and what influences the strength of electromagnets. Instructions included.
Enclosed to prevent air currents from affecting the deflection of leaves. Each leaf is suspended from two small hooks. The leaves pivot, rather than bend, when charged. The front and rear side of the box is made of square glass to allow visibility. supplied with a booklet of 6 leaves.
A pair of light weight balls are suspended from a rod with a piece of string. The support rod is mounted on an insulated base. Provides a simple yet effective way to learn about electrostatics.
Flask type, conical flask with rubber stopper which holds a metal rod with disc top and lower flat end to which a leaf may be pasted. Supplied with a booklet of 6 leaves and instructions for fitting.
