Magnets

Scholars build a compass using a needle, cork, magnet, and a water-filled cup in order to locate the magnetic north and south.

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...

Scientists need to figure out how to measure interplanetary magnetic fields, but the magnetic field of the spacecraft is interfering with their readings. Scholars attempt to solve the problem that has perplexed NASA scientists for years.

Attract learners to an interesting lesson! The third in a 14-part series of lessons on electricity and magnetism uses a hands-on approach to exploring magnetic fields. Scholars experiment with a compass to test Earth's magnetic field and...

Have your class create their own compass. Using a needle, a container of water and a magnet, have learners explore magnetism. They will love making this useful tool and it will reinforce the fact that Earth has a magnetic field.

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.

Students investigate magnetic evidence that supports the theory of sea floor spreading.

You'll be strangely drawn to this activity! Physical science pupils learn how compasses work in an interesting interactive. The content covers magnetic poles, Earth's magnetic field, and what would happen if Earth's poles swapped places.

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...

Students explore magnetism.  In this "magnets" science instructional activity, students make a compass with common household items and explain the relationship between what a compass does and the earth's magnetic fields.
