For this physics lab students investigate whether Ohm's Law applies to common electric devices. Students submit their findings in a written report or class discussion.

Students use conductivity meters to measure various salt and water solutions, as indicated by the number of LEDs (light emitting diodes) that illuminate on the meter. Students create calibration curves using known amounts of table salt...

Build circuits with resistors, light bulbs, batteries, and switches. Take measurements with the realistic ammeter and voltmeter. View the circuit as a schematic diagram, or switch to a life-like view.

Learn how heat energy can be produced by mechanical and electrical machines.

Generate electricity with a bar magnet! Discover the physics behind the phenomena by exploring magnets and how you can use them to make a bulb light. Java required.

An electronics kit in your computer! Build circuits with resistors, light bulbs, batteries, and switches. Take measurements with the realistic ammeter and voltmeter. View the circuit as a schematic diagram, or switch to a life-like view....

Anders Celsius is most familiar as the inventor of the temperature scale that bears his name. The Swedish astronomer, however, also is notable as the first person to make a connection between the radiant atmospheric phenomenon known as...

Most of us have seen the rainbow-hued breakdown of the composition of light. Light is of course a form of energy. A magnetic field changes the behavior of light- a phenomenon known as the Zeeman effect.

What four arrangements would result in the successful lighting of a lightbulb? And more importantly, what does each of the four arrangements have in common that would lead to an understanding of the two requirements of an electric...

James Clerk Maxwell was one of the most influential scientists of the nineteenth century. His theoretical work on electromagnetism and light largely determined the direction that physics would take in the early twentieth century. Indeed,...

A set of four online courses in Physics for elementary and middle school teachers. Each course targets a different topic area - light, electricity & magnetism, temperature & heat, and force, motion, & energy.
