0 learners earned this badge

Our Argonne researchers work with batteries all the time. Recently, they’ve been studying how different materials affect battery capacities, recharging rates, and longevity of batteries. Many batteries we use today are considered “secondary” batteries, also known as “rechargeable.” Secondary batteries, like those found in your phone, use a chemical reaction to generate electricity to power your device. When plugged into a charger, the electricity from the wall reverses the chemical reaction, thus “charging” the battery. The current and resistance are two variables that will impact charge time. Current is the flow or movement of electrons in the circuit and resistance is a force that opposes current, meaning it makes it more difficult for the electrons to move. Basically, the lesser the resistance the faster the current, which means the faster the charge! There are a number of factors that impact resistance such as the length of the circuit. How do you think length impacts resistance? Which cable has more, shorter one or a longer one? Are there other factors to consider? Try the experiment below to help us find out!

  • Completed Cybersecurity Escape Room

    Cybersecurity, phishing, ransomware, the dark web. You probably have heard of these things, but what are they and why are they important? By earning this badge, you will explore the world of cybersecurity, an exciting area of computers and technology that focuses on protecting people while they are online. Team up with Argonne cybersecurity experts to stop an attack on a car before it gets turned into a 1-ton brick!

  • Smart Charging Challenge

    Imagine: your friend is getting ready to head out for the day and their phone gives them a low battery charge warning. They only have ten minutes before they must leave. They have several charging cables to choose from, all different lengths--Which one should they choose? Is there an optimal length to charge your phone? How much can you increase the charge on your phone in 10 minutes? Are there any other factors at play? In this activity, you will measure how much your phone’s battery charges in 10 minutes. You will then submit your results to the Argonne Smart Charging Data Form. Your submission will be one data point within a larger experiment tested by students from all over! Your findings will help answer the questions above.

  • 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!

  • Tame the Particle Challenge

    “Atoms are the building blocks of matter” is probably something you have heard before. You may also remember learning that atoms are made of three types of particles: neutrons, protons, and electrons. But did you know that charging and accelerating a beam of electrons or protons near the speed of light can help us answer some of societies greatest questions, like "Why did the T-rex have such small arms?" Taming these energetic particles is a delicate balance. Let’s see how well you can do it!
