In these electricity worksheets, students learn about electricity, how its used, how it can be changes, and electricity circuits. Students complete an 11 page packet about electricity.

Students define what a redox reaction is. In this chemistry lesson, students electroplate some wires in the lab. They research the application of electroplating in the real world.

Students explore series and parallel circuits. In this physics instructional activity, students construct a simple circuit and measure its maximum current. They construct their own voltmeter and ammeter that operates at a specified range.

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...

Simple homemade batteries are described that can be made from items found in the home or school lab. These experiments help students understand how to wire them up, the origin of current, voltage and power, as well as the chemistry that...

Video considers the prospects for battery-powered electric cars and asks if they can compete with gas-powered ones.

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

In this experiment, students will learn how to make a battery with a water solution and two types of metal. This is then used to power an LED light. Includes video demonstration.

Batteries are expensive to purchase in a store, but you can make one your self for exactly 24 cents. In this experiment, you will make your own voltaic pile using pennies and nickels and determine how many coins in a pile will make the...

Learn how to create electricity and your own electrical gadgets! Site provides users with information on how to make a battery, flashlight, buzzer an electric motor.

[Free Registration/Login Required] Explore how batteries use redox reactions to create electrical energy to power a flashlight.

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 article discusses New England's developing hybrid power grid, a network that relies on a variety of energy resources, including fuels and alternative energy sources and technologies. The ongoing transformation to renewable energy is...

Batteries are a triumph of science-they allow smartphones and other technologies to exist without anchoring us to an infernal tangle of power cables. Yet even the best batteries will diminish daily, slowly losing capacity until they...

Create a battery that is strong enough to power a light or a small motor in this activity. Activity uses simple materials such as: aluminum foil, salt water, and charcoal to make this battery.

A discussion of various principles related to voltage. The operation of battery testers and voltmeters are explained. The importance of the internal resistance of a power source is discussed.

You will learn about a voltaic battery and to see if it's powerful enough to light up a light bulb

Review the components of a circuit and their symbols such as battery, resistor, and switch. Analyze how the power of a resistor is related to the current and electric potential difference across the resistor.

This is an article about finding the proper element to develop a radioisotope power generator to provide a power source for equipment that is too remote or inaccessible for replacement such as satellites.

Students act as engineers to apply what they know about how circuits work in electrical/motorized devices to design their own battery-operated model motor vehicles with specific paramaters. They calculate the work done by the vehicles...

This set of activities has students using everyday items (batteries, magnets, compasses, iron and paper clips) to reveal the connection between electricity and magnetism. Ideally, students will already have experience building simple...

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

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...

Explains the design of two circuits that can flash an LED from a single 1.5V battery. A typical LED needs 2-3V to work properly and both these circuits include a voltage doubler to boost the voltage to drive the LED. Both circuits will...
