Magnetic Shielding
Elementary magnetologists investigate magnetic shields using a variety of materials in a "shielding sandwich." While the activity isn't novel, it is engaging, and this particular resource includes a brief explanation of the phenomena...
Teach Engineering
Circuits and Magnetic Fields
Have your class use compasses to try to find the magnetic field around an electric current. Groups use the same technique to visualize magnetic fields as they did in the second activity in the series, but this time, the field is...
Teach Engineering
Magnetic or Not?
The class must determine the magnetic properties of different materials, including aluminum and steel by sorting through materials using a magnet. Groups make a prediction on whether a material is magnetic and then perform...

Visualizing Magnetic Field Lines
Magnetic fields might not be a field of dreams but they are useful. Class members observe the reactions of magnetic fields using a compass, iron filings in a paper container, and iron filings suspended in mineral oil.
Teach Engineering
Magnetic Fluids
Teams work as material engineers to create ferrofluids, whose shape is influenced by magnetic fields. The activity, which is the fourth in the six-part series, has the teams create magnetic ink and use it to write, testing it with a...

Science Activity 2: Light & Sound
Little learners experiment with sunlight and map out how light travels. Using a mirror and slotted card, they find out about items that can reflect or absorb the light. They experiment with a variety of materials to find out how light...
Exploratorium
Motor Effect
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.
Exploratorium
Magnetic Suction
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...

Make Your Own Compass
Scholars build a compass using a needle, cork, magnet, and a water-filled cup in order to locate the magnetic north and south.
Exploratorium
Circles of Magnetism IV
Hang a strip of foil on a stand and form a loop out of it. Then attach the clips of a battery-operated circuit to the loop to see its sides repel each other. This simple demonstration is applicable and easy to add to your lecture on...

Create a Compass
Historically, humans have used many methods of finding due north. Using a hands-on activity, learners create their own compasses. They then test their compasses in their neighborhood or to assist with stargazing.
Exploratorium
Eddy Currents
Make electromagnetic eddy currents evident with this demonstration. You will need to gather a few materials from the local hardware store and a strong neodymium magnet, but the visual value is well worthwhile.
