Audio speakers, hard drives, credit cards, and even the earth use magnetic fields. While we observe the effect of magnetic fields, we can't actually see them. A viewer helps participants explore magnetic fields, some of the items that...

Fifth graders investigate simple circuits and identify when a circuit is considered opened or closed. In small groups, they experiment with wires, batteries, and light bulbs to identify how to light the bulb. Students also experiment...

Students explore the properties of electricity.  In this electricity lesson, students construct an electric game board circuit using their knowledge of a series electrical circuit. Students develop game ideas based on current...

Students explore the differences between parallel and series circuits by designing and constructing several different circuits. In small groups, they use miniature light bulbs, wires, and nine-volt batteries to build the circuits they...

Students discover the basic principles of circuits by designing and testing some of their own. They are told that circuits usually have a power source such as a battery and a resistor such as a light. Students make a circuit using a...
