Build Your Own Battery Challenge
Build Your Own Battery Challenge

0 learners earned this badge

Batteries come in all shapes, sizes, and materials. A basic battery has two different metal electrodes (a “positive” end and “negative” end), an electrolyte solution, and a separator or “membrane.” The electrolyte solution in a basic battery is the liquid, gel, or paste that allows electrical charge to flow between a negatively charged metal and a positively charged metal in a battery. The separator is a membrane that keeps the two metals from touching so that the battery doesn’t short-circuit. In this activity, you will create your own battery at home and experiment with different materials. Share your project with Argonne Education!

  • Mine Your Trash: Upcycle Your Plastics Challenge

    Have you ever heard the phrase: “One person’s trash is another person’s treasure”? Trash bins and landfills are filled with valuable materials! Materials that we can make into new, shiny, and useful things. Join us in our “Mine Your Trash” challenge to reduce the number of items that end up in landfills!

  • Coat the Fuel Pellet Challenge

    Argonne scientists have discovered a new way to coat nuclear materials that are used to help create electricity in nuclear power stations. Nuclear reactors are devices for creating a nuclear chain reaction to generate electricity. Inside an operating nuclear reactor, the environment is extreme. Reactor components are exposed to a combination of intense radiation (energy that can be harmful) and heat as well as coolant. That's why, in order to operate reactors safely, scientists need to design their components with materials that can withstand these conditions. Inside nuclear reactors, the radioactive fuel provides the energy that is turned into electricity. Coating these components can help improve the operation and safety of nuclear reactors. Today, you will make your own coatings with materials from around your house.

  • Which Planet is the Flattest Challenge

    What shape are the planets? It’s likely not what you think. In this activity, you will create your own model of a rotating planet and make some observations. Then, determine which planet is indeed the flattest.
