Science Fair Project Idea
Batteries are expensive, but you can make one for exactly 24 cents! In this experiment, you will make your own voltaic pile using pennies and nickels. How many coins in the pile will make the most electricity? Read more

Imagine telling your friends about your latest science project: using a battery to make a light turn on. You might get some blank stares...sounds a little boring and basic, right? Now tell them you will do it with a potato! Yes, you can actually use fruits and vegetables as part of an electric power source! Batteries power many things around you, including cell phones, wireless video game controllers, and smoke detectors. In this science project, you will learn about the basics of battery… Read more

Drones—also called quadcopters or unmanned aerial vehicles (UAVs)—are an increasingly popular toy for hobbyists. Some companies even want to use them for business purposes, like delivering packages right to your doorstep! However, drones typically have a rather short battery life. Does the added weight of a package affect a drone's battery life? Try this project to find out! Read more
Science Fair Project Idea
Solar cells are devices that can be used as a source of power when there is light shining on them, but they stop producing energy when they are not in the light. One way to store the solar energy for later use is to use a solar cell to charge something called a capacitor. The capacitor stores the energy as an electric field, which can be tapped into at any time, in or out of light. In this electronics science project, you will use parts of a solar car to experiment with the energy storage… Read more

You probably use batteries to power different devices every day, ranging from toys to TV remotes, without giving it much thought. Figure 1, below, shows some common types of batteries. Eventually the batteries will die and you have to replace them with new ones (or recharge them if they are rechargeable batteries). How much do you actually know about how batteries work? This abbreviated project idea will give you some suggestions to investigate how batteries perform in common household… Read more
Science Fair Project Idea
Have you ever wondered how your cell phone or laptop keeps running once you unplug it? Sure, it is the battery that makes your portable electronics work, but how exactly does a battery do that, and from where does the electricity come? Generally, in a battery chemical energy is converted into electrical energy. In fact, many different types of batteries exist that are all based on a different set of chemical reactions. In this science project, you will explore a special battery variant called… Read more
Science Fair Project Idea
Have you ever gotten a shock touching a doorknob after walking across a carpet? Static charge is responsible for that shock. Wouldn't it be cool to save up and store all of that charge in a homemade jar? It would almost be like storing lightning. This science project will show you how to do that. Read more
Science Fair Project Idea
You can take advantage of electrochemistry and make a battery to clean tarnished silverware without scrubbing. You should learn about how batteries work and study oxidation-reduction reactions so that you can explain how this process works. You'll need a pan large enough to hold the pieces of silverware, and deep enough to cover them in solution while boiling gently. Line the pan with aluminum foil, and place the silverware inside the pan, making sure that each piece touches the foil. Add… Read more
