How does a direct current run a motor? Pupils control five variables in an electric motor and observe how the force diagram changes. The force, magnetic field, and current vary based on the changes in the design of the magnet and...

Students investigate the properites of a semiconductor device known as a diode. They recognize a diode as a one way conducting device. They describe alternating current and the use of a diode to convert it to direct current. Students...

Essentially a list of definitions, this slide show will help your students understand the generation of electrical currents using magnets.  There is information comparing the frequencies of currents produced and two slides to detail...

Use a simple PowerPoint presentation to introduce you environmental studies class to hydropower. Hold a debate about the pros and cons of developing this form of alternative energy. Power up your class with this simple lesson on a topic...

This lesson is preparation-intensive, but well worth the investment. You will construct five or six portable testing stations with which lab groups will gather data on the best position for collecting sunlight with a solar panel. This is...

Rise and shine! Class members collaborate to construct a photovoltaic solar cell with two semiconductor layers, as guided by this fabulous lab sheet. They test its output with an ammeter or galvanometer. 

How does electricity work? Budding scientists explore the concepts of electrical currents and open and closed circuits with class discussion and a hands-on activity using a battery to turn on a light bulb. Learners also make predictions...

High voltage power lines deliver electricity to homes, but each home requires low voltage. How does the energy get converted so it can be used safely? Pupils explore alternating current and transformers through a simulation. They control...

I don't get electricity jokes, watts so funny about them? The 13th in a series of presentations covers energy, motors, currents, generating electricity, calculating electrical energy cost, transformers, and batteries.

Third graders discuss electric currents. In this circuit lesson, 3rd graders create a picture of a battery circuit and a light bulb. They show the positive and negative charge and the flow of electrons. 

Students study the concept of electricity, what an electric current is and its relationship between voltage and resistance.For this electrical lesson students solve problems using Ohm's law, and research alternative sources of electricity.

In this electricity worksheet, students answer 17 multiple choice questions about electricity, how it is measured, the types of currents, the types of meters and circuits. Students also answer multiple choice questions about protein...

What a wonderful way to explore wind power! Through this lesson, learners get a background in the history of wind power, create their own wind turbine, and the test their designs. This is a terrific way to tie scientific principles to...

Sixth graders investigate the concept of energy using a hypothetical story. The power goes out in their house and they no longer can play your videogames. Students must create your own alternative power source. This story sets the stage...

Young scholars describe an electrical current and the factors that determine the resistance of an object.  In this electrical current lesson students discuss their knowledge of voltage, current and resistance.

Investigate the construction of the electric circuit with a thorough presentation that provides a solid background for each type of circuit. After introducing key vocabulary, the lesson goes on to explain circuit design.

Physical science or technology classes will be invigorated by this challenge: to convert a toy, game, or other device to run on solar power. In doing so, they will design the appropriate solar arrays. This is an A+ lesson, complete...

Take a look at an organized physics course. The 34-section electronic textbook covers material in AP® Physics 1 and 2. Teachers use the text to supplement lectures and have the class work through the labs. Each section contains...

In this online electricity worksheet, students are asked 10 questions about electric current and battery energy, an online answer key provided.

The Green Education Foundation found that this lesson plan, written by the Texas State Energy Conservation Office, is right up their alley when it comes to teaching sustainability. It is ideal as a first lesson plan on photovoltaic...

A solar cell is similar to a rechargeable battery in many ways. Science lab groups connect each in a series circuit to run a mini motor and then compare and contrast them by answering questions and completing a Venn diagram. This is an...

I get a charge out of this. In order to learn how a generator works, groups build and test one in this ninth lesson of the series. The generators are tested at low speed and high speed to determine the watt output and whether they have...

Third graders discuss how energy is created. In this energy lesson, 3rd graders look at how a city receives energy and how it is made. They create their own generator using a pin wheel and pipe cleaners. 

Students discuss how people are reducing their fuel consumption, then read a news article about a new bike-sharing program in Washington, D.C. In this current events and alternative transportation lesson, the teacher introduces the...
