This activity demonstrates Lenz's Law, which states that an induced electromotive force generates a current that induces a counter magnetic field that opposes the magnetic field generating the current. In the demonstration, an empty aluminum can... (View More)

Keywords: Magnetism; Lenz's Law
Audience: High school
Materials Cost: $1 - $5 per group of students

This is an activity about the magnetic fields of the Sun and Earth, and the interplanetary magnetic field, or IMF. Learners will engage in a question and answer dialogue, make connections using bar magnet examples and overhead transparencies, and... (View More)

This is an activity about the properties and characteristics of Earth’s magnetic field as shown through magnetometer data and its 3D vector nature. This resource builds understanding of conceptual tools such as the addition of vectors and... (View More)

This is an activity about magnetic induction. Learners will induce a flow of electricity in a wire using a moving bar magnet and measure this flow using a galvanometer, or Am meter. Through discussion, this activity can then be related to magnetic... (View More)

This is a resource that explains the rationale behind the multiple time zone divisions in the United States. Learners will work through a problem set to practice calculating the time in one time zone, given the time in another time zone. This is... (View More)
