[Free Registration/Login Required] This short biographical piece shares information about Thomas Edison, the inventor of the phonograph, light bulb, motion picture camera, and more. This passage is a stand-alone curricular piece that...

Through informational text, interactive activities, practice problems, and virtual simulations, students learn about the basic properties of electricity in this unit.

The official Nobel biography of William Lawrence Bragg. the son of William Henry Bragg, who shared the 1915 Nobel Prize in Physics with his father. This article focuses on Bragg's science activities, positions, and achievements and honors.

This site from The Exploratorium Museum is a full description of a short activity. An electrophorus plate and a Leyden jar are made. The electrophorus is charged by induction. Its charge is transferred to the Leyden jar by conduction...

A simulation investigating a parallel-plate capacitor which is charged by connecting one plate to the positive end of a battery, and the other plate to the negative end. The battery sends electrons from one capacitor plate to the other...

In this simulation, investigate the force between charged objects. Rank three charged objects of different magnitudes, then create a method to determine the ranking of the charge magnitudes. Finally, devise a new method of determining...

Simulation showing the simplest RC circuit, with a resistor and capacitor in series with one another, and a battery that can be switched in the series, or switched out of the circuit.

Investigate the idea of the force between straight current-carrying wires in this magnetic force simulation. See if you can rank the wires from largest to smallest based on the magnitude of their currents.

This simulation demonstrates a rotating conducting disk in a magnetic field which produces a current or a self-exciting dynamo.

In this interactive learning module, students learn about the basic properties of magnetism. Practice problems are provided for ongoing assessment.

Review the key terms and skills related to Kirchhoff's loop rule, including how to determine the electric potential difference across a component.

At the turn of the 19th century, scientists were beginning to gain a rudimentary understanding of electricity and magnetism, but they knew almost nothing about the relationship between the two. Baltic German physicist Heinrich Lenz took...

Gerd Binnig co-developed the scanning tunneling microscope (STM) with Heinrich Rohrer. The STM allowed scientists entry into the atomic world in a new way and was a major advance in the field of nanotechnology. For their achievement,...

The integrated circuit fueled the rise of microelectronics in the latter half of the twentieth century and paved the way for the Information Age. An American engineer, Jack Kilby, invented the integrated circuit in 1958, shortly after he...

Heike Kamerlingh Onnes was a Dutch physicist who first observed the phenomenon of superconductivity while carrying out pioneering work in the field of cryogenics. An important step on the way to this discovery was his success in...

Isidor Isaac Rabi won the Nobel Prize in Physics in 1944 for his development of a technique for measuring the magnetic characteristics of atomic nuclei. Rabi's technique was based on the resonance principle first described by Irish...
