In this science project, you will be creating your own electric generator. Using cardboard, a nail, wire and magnets you'll be able to recreate the process of generating electricity for your home and light a small light bulb.
Introduction
Goal: Create an electric generator that can light a small light bulb
Age: Middle school and up
Safety concerns: An awl can be sharp, get an adult to help you. Hot glue can burn you, be careful not to get any on your skin. Neodymium magnets are very strong. Keep them away from electronics.
Time: 2 hours
All of us love electricity. From charging our phones to watching the latest news story unfold, electricity is an integral part of our daily lives. But, have you ever thought about how electricity gets to your house? We all know it comes from a power plant, but how do you actually 'make' electricity? Power plants contain huge generators, or turbines, that convert mechanical energy into electrical energy.
A popular topic today is how to use renewable energy sources, like wind, water, or solar energy to make electricity for our homes. For more information on types of renewable energy, you can watch this lesson: What Is a Renewable Energy Source? - Definition & Example.
Wind and water plants use mechanical energy generated by wind, or falling water to spin their turbines. To refresh yourself on how wind and water turbines work, you can check out this lesson: Creating Energy from Solar, Wind, and Water Sources. The turbines spin large coils of wire around a magnet, which creates electricity.
Today, we're going to build our own miniature electric generator, just like the ones in a power plant. Although we won't be able to power an entire city using our generator, we will be able to light a small light bulb.
Materials
A piece of cardboard 3'' wide by 12'' long
Hot glue
One neodymium magnet smaller than the constructed cardboard housing
200 feet of 30 gauge enamel coated copper wire
One 1.5 volt light bulb
Light bulb holder (optional)
Alligator clips (optional)
Ruler
Pencil
Awl or other device to puncture the cardboard
Steps
1. Start by measuring the cardboard to create a box. Mark off 3.1'', then make another mark at 4.5'', 7.7'', and finally 8.9''.
2. Now, fold the cardboard along the marks you just made to construct a box.
Safety Tip!! Hot glue is very hot, be careful not to get any on your skin.
3. Glue the box shut using the hot glue gun at the overlapping edges.

Safety Tip!! An awl is very sharp. Get an adult to help you with this step.
4. Next, puncture a hole in the center of the long side of the box on both sides using the awl.
5. Now, slide the nail through the hole.
Safety Tip!! Neodymium magnets are very strong. Keep them away from all electronics!
6. Using the hot glue, attach the magnet to the nail. Make sure there is enough room for the magnet to rotate freely, yet fits as snuggly as possible into the box.
7. Next, wrap the wire around the outside of the box covering the cardboard. Leave about 5'' on either end of the wire to attach it to the light bulb.
8. Now, place your light bulb in the light bulb holder (if you are using it) and secure the wire to the holder using the alligator clips.
