Fields is an inquiry-based educational resource focused on establishing the reality of electric, magnetic, and gravitational fields. The accompanying video features researchers discussing the central role that fields play in modern physics.
Activities begin with an exploration of the nature of fields and the models that describe them. Students develop a physical model for electric fields and then test it using LEDs. They construct mathematical models that describe electric and magnetic fields and compare these to Maxwell’s equations. Students further explore the reality of fields as they investigate how auroras form. The nature of the gravitational field—as understood by Einstein—is applied to the orbit of Mercury to provide a model for orbital precession. The final activity is a design challenge that introduces students to magnetohydrodynamic propulsion.
This digital resource is designed to excite learning in Science, Technology, Engineering, and Math (STEM), with an emphasis on global competencies—including critical thinking and problem solving, collaboration, and communication.
