Heat things up in your physical science class with this interactive lesson series on thermodynamics. Through a series of class demonstrations and experiments, young scientists learn how heat is transferred through conduction,...

Transmit sound with an electromagnet. Class members follow the provided direction and build an electromagnet that will transmit sound though a cassette-tape player. As as extension they create an air core electromagnet and...

Drive an electric current through a coil of wire and show how it can pull a nail right into its core. This vivid demonstration exhibits the electromagnetic field. Consider also showing your class a few of the devices that make use of...

How do you demonstrate radio transmissions? Pupils build a low-energy radio transmitter by constructing two coils from magnet wire and connecting them to audio/phone plugs. The resource provides the details on how to build the...

The magnetic wire. Class members create a magnetic field by running electricity through a wire. The video included in the resource provides information on how this effect is used to make electrical motors.

What is the difference between a comet and a meteoroid? An educational lesson includes five demonstrations of how the atmosphere can inhibit our ability to measure many things in the galaxy. 

Light and sound go hand in hand. Pupils set up a system that will emit sound when a laser is directed at a photodiode. Various objects, such as a comb and talcum powder, allow for modulation of the laser beam. Individuals also...
