- Abstract:
-
In this activity best suited as a demonstration, learners observe that when a piece of iron gets too hot, it loses its ability to be magnetized. The temperature at which this occurs is known as the Curie Point. This simple set-up involving a lantern battery and Tinkertoys demonstrates this phenomenon. Adult supervision required, as the wire will get hot in this activity.

- Abstract:
-
In this activity and demonstration about electricity and magnetism, learners observe how the current generated when one copper coil swings through a magnetic field starts a second coil swinging. Learners also explore what happens when they change the polarity of the magnet, reverse the coil, or add a clip lead to short-circuit the coils. Use this activity to illustrate how electricity and magnetism interact. The assembly of the electromagnetic swing device takes about an hour.

In this activity, learners make a 3-D model of magnetic fields by inserting a small, strong magnet into a sphere. When learners sprinkle used staples onto the sphere, they'll see how the field works, as the orientation of the staples will change with "latitude." Adult supervision recommended. This resource also includes information about Iceland's unusual volcanoes, which have magnetic fields that seem to defy the Earth.

Learners build a simple electromagnet, then use this electromagnet to transform a yogurt container into a working speaker. They can connect their speaker to a radio and listen as it transmits sound. This activity requires learners have some background knowledge about series circuits and magnets. Resource contains vocabulary definitions and suggestions for assessment (sample rubric included), extensions, and scaling for different levels of learners.
