Curated OER
Plotting a Magnetic Field
Students experiment with a set of materials. They plot the magnetic field that arises from a regular bar magnet. They discover how a magnet affects a compass.
Curated OER
The Magnetic Sun
Learners follow steps to build a simple version of a magnetometer, an instrument capable of detecting areas of strong magnetic field. Students use the magnetometer to investigate models of the Sun and examine images of the Sun.
Curated OER
Magneto-hydrodynamic Drives
Students examine how electric and magnetic fields can be used to force water out of a chamber to move a vehicle forward.
Curated OER
Magnetism in Action
Third graders experiment with magnetic force and magnetic fields. They examine how magnetic forces can act through a distance.
Curated OER
Magnetic Fields and Bermuda Triangles
Students use a compass to determine the direction of a magnetic field at any point in space. They explain how two magnetic fields combine, then predict the location of areas where two fields can cancel each other to leave no resultant...

Using "Student Power" to Generate Electricity to Run a Portable Compact Disc Player
Students conclude that magnets and magnetic fields can produce electricity. Students also understand how a small motor works and how gears work. Students describe how energy can transform along a pathway.

How Are Magnetic Fields Related To Sunspots?
Students discover that sunspots are the result of intense magnetic forces on the photosphere of the sun by observing images from the SOHO satellite.
