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...
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 web page explains the physics of sonic shock waves. Text and animations describe and illustrate the wavefronts of sound from a moving point source for the cases of motion equal to, less than, and greater than the...
This activity from the Exploratorium provides a classic science demonstration of the buoyancy of a Cartesian diver, named after scientist René Descartes. A diver made from an eyedropper or Bic? pen is made to float, si...
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,...
