Students use potatoes to light an LED clock (or light bulb) as they learn how a battery works in a simple circuit and how chemical energy changes to electrical energy. As they learn more about electrical energy, they better understand...

This activity helps students understand how a motor in a LEGO MINDSTORMS NXT robot uses electricity produced by the battery to move a robot to do useful work in the form of throwing a ball. Students relate the concepts of electricity and...

This lesson plan introduces electricity, batteries and motors using a LEGO MINDSTORMS NXT robot. The associated activity guides students to build a simple LEGO NXT set-up and see the practical implementation of the concepts discussed....

Everything you ever wanted to know about every household product available, from battery disposal to detergent and glue.

Listen and learn how the battery converts energy using voltaic cells. Learn how anodes and cathodes aid in oxidation and reduction. Discover how voltage and electrolysis direct the current.

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.

Explore the interactions between a compass and bar magnet. Discover how to use a battery and wire to make a magnet.

Shake N' Light flashlights have been advertised on televisions across the nation in the recent year. But many do not understand just how they get energy to light up the bulb without using batteries. Do this experiment to make your own...

This is a Java tutorial showing the simple voltaic (or galvanic) electrical cell, which is the most basic type of "wet" cell and demonstrates the fundamental chemistry behind batteries.

When there is a power failure, or when we go outside at night, we grab a flashlight so we can find our way. What happens inside a flashlight that makes the bulb light up? Why do we need a switch to turn on a flashlight? Have you ever...

This lab demonstrates Ohm's law as students set up simple circuits each composed of a battery, lamp and resistor. Students calculate the current flowing through the circuits they create by solving linear equations. After solving for the...

A unit providing opportunity for students to explore circuits and switches through homemade battery powered cars.

Understand the energy transformations that happens when you light a bulb with a battery. Activity requires students to build a simple circuit and take temperature and time measurements. Lab includes procedure with questions that can be...

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

Discusses the design of a meter for measuring the power output from a set of seawater batteries.

Create your own simple electric circuit. Using simple supplies build your own battery and investigate conductivity. You can also construct a crossword puzzle with electrical vocabulary words.

We use batteries in different ways almost daily. Read this article to find out about batteries and how they work.
