What kind of unit conversion would you like to do? This site will allow you to do a multitude of conversions. Just click on the specific measurement you are needing to convert. It also provides a history of measurements and a chart of...

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.

Student teams measure voltage and current in order to determine the power output of a photovoltaic (PV) panel. They vary the resistance in a simple circuit connected to the panel to demonstrate the effects on voltage, current, and power...

Students use watt meters to measure the power required and calculate energy used from various electrical devices and household appliances.

Read about the device used for measuring resistance in a circuit which was discovered in 1843, but had been invented a decade earlier. The inventor's name was not Wheatstone.

After discovering the nature of electrical resistance, scientists devised instruments like this one to measure and control it. (Java tutorial)

This tutorial illustrates how a galvanometer, an instrument that detects and measures small amounts of current in an electrical circuit, works. (Java tutorial)

This circuit is most commonly used to determine the value of an unknown resistance to an electrical current.

This lab is designed to have students determine the charge on a series of oil drops that are suspended in an electric field. Students will measure the size of the drop in an effort to determine the force gravity on the drop. They will...

This investigation has students investigating and measuring the decay of batteries as their electric charges are used up in circuits.

Build circuits with resistors, light bulbs, batteries, and switches and take measurements with laboratory equipment like the realistic ammeter and voltmeter.

Students perform the first steps that environmental engineers do to determine water quality - sampling and analysis. Student teams measure the electrical conductivity of four water samples using teacher-made LED conductivity testers and...

Here you can find what you need to scientifically assess battery performance. In this exercise (that should take about one week) learn how batteries work, how they wear out and most importantly, how to make valid measurements to assess...

Students learn about how a device made with dye from a plant, specifically cherries, blackberries, raspberries and/or black currents, can be used to convert light energy into electrical energy. They do this by building their own organic...
