In this activity, students make a battery using different fruits and vegetables, a copper penny, and a zinc washer. They use a voltage probe to collect data on voltage and compare the values of different 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...

Students make a simple conductivity tester using a battery and light bulb. They learn the difference between conductors and insulators of electrical energy as they test a variety of materials for their ability to conduct electricity.

Try out this great electricity activity by using lemons to make a light bulb glow. You can learn about the science behind the activity and watch an animated demonstration.

This site presents a procedure for creating your own electromagnet using an iron nail, some wire, and a battery. The site illustrates a connection between electricity and magnetism.

Test your electrical skills! Can you make a working glow stick with a nine-volt battery and a strand of lights?

Students will demonstrate how an electric current can make an iron object magnetic by building an electromagnet with a steel nail, insulated wire, a simple switch, a battery/cell, and small metal washers. Students predict the number of...
