Self-adhesive conductive patches designed to be used with EKG Sensors. (one year shelf life).
This highly visible elastic cord can be used to set up standing transverse waves with the Mechanical Wave Driver.
A simple model for demonstrating electric fields between various electrode configurations. Place liquid paraffin in the 90mm petri dish and sprinkle semolina or fine grass seed (not supplied) on the surface.
A fool-proof system for allowing students to investigate the raising of a mechanical load by an electrical input.
Ideal for keeping sensors in place during experiments, this support connects to standard ring stands with an adjustable screw.
This electromagnet has a magnetic field strength over 1 Tesla.
A self-contained unit allowing students to study the effect of current and number of coils on the strength of an electromagnet.
Show the amount of charge and the sign of the charge relative to a standard. Includes charging ball plus a set of condenser plates with insulated rod.
A pack of 20 strips each measuring 200 x 25 x 2mm. Ten are polycarbonate and ten are polystyrene. When the strips are rubbed with a cloth they acquire opposite electrostatic charge for investigations into attraction and repulsion.
Lightweight ribbons are connected to a stand which rests on top of the High Voltage Van de Graaff Generator. Ribbons stand on end due to the repulsive force between their like charges.
Brass wire holders for supporting plastics strips in electrostatics experiments. Ten per pack supplied with a reel of monofilament nylon for hanging.
When connected to the sphere of the Van de Graaff Generator the spokes are propelled by charge leaving the points.
This electrostatics kit provides the necessary tools to separate positive and negative charges. Students can experiment with different combinations of cloth and rod materials to explore how each becomes charged.
Features 29 inquiry based labs designed for elementary students and coordinated with the standards for life, earth and physical sciences.
Includes the two complementary wireless sensors to the Elementary Science Starter Lab Station.
