In this learning assessment, students demonstrate understanding of the following concepts: solids, liquids and gases, changes of state, convection, and density. Students create a skit where the actors and actresses are molecules, and dramatize,... (View More)

Audience: High school
Materials Cost: Free per group of students

This is an activity about the Kp index, a quantification of fluctuations in the Earth's magnetic field due to the relative strength of a magnetic storm. Learners will take a reading from a magnetometer site and make a Kp index estimate to predict... (View More)

This is an activity about how to measure the interplanetary magnetic field, or IMF. Learners will act as scientists and engineers at a conference to explain their discoveries from earlier activities of the larger resource where they designed their... (View More)

Audience: Middle school
Materials Cost: Free

This is an activity about the basic properties of magnets and magnetism. Learners explore concepts such as magnetic fields and polarity, which form the basic ingredients of a study of Earth's magnetic field and the technology of magnetometers.... (View More)

This is a lesson about the magnetic field of a bar magnet. The lesson begins with an introductory discussion with learners about magnetism to draw out any misconceptions that may be in their minds. Then, learners freely experiment with bar magnets... (View More)

Audience: Middle school

This is a lesson about magnetism and solar flares. Learners will evaluate real solar data and images in order to calculate the energy and magnetic strength of a solar flare moving away from the Sun as a coronal mass ejection. This is Activity 3 in... (View More)

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)
