This research studies students' functional understanding of magnetic induction, the process by which changing magnetic flux induces electrical current in a circuit. Functional understanding includes the ability to...
One commonly stated instructor goal for an introductory calculus-based physics course is to improve students? problem solving skills. There is, however, a growing body of research evidence to suggest that this goal is n...
In this activity from the PTRA manual "Role of the Laboratory in Teaching Introductory Physics", students set up their first circuit using meters and specially made resistors in heat sink boxes (not required), which do...
This student activity is designed to explore the potential energy of springs. By hanging different masses on a spring, students are lead to determine the potential energy in a stretched spring. Included are notes for...
This activity from the Exploratorium contains an introduction to diamagnetic materials like water that are repelled by both poles of a magnet. A rare-earth magnet is used to repel grapes, whose main component is water,...
