. . . . . In the Take charge: global battery experiment learners can explore batteries and the important role they play in a sustainable future by making their own. There are two investigations in this global experiment. Both experiments give learners a chance to build a coin battery and practise scientific enquiry skills.
The global battery experiment will run until 31 July 2023, so you can take part and share your results at any time before then. Join the experiment Join our 2022 global experiment to investigate the science behind batteries and find out how you can contribute to building a more sustainable future.
Taking part in our global battery experiment will help you to understand how batteries work and their huge potential as a tool in the transition to more sustainable sources of energy. And it might inspire you to study further and even pursue a career as a scientist working towards a brighter energy future.
The simple battery experiment uses the principle of galvanic action. A galvanic cell is created by using two different metals separated by an electrolytic medium. The electrolytic medium is the saltwater saturated into the pieces of coffee filter. The experiment only produced a nomimal amount of voltage when a single cell was used.
Using some coins and saltwater, a simple battery is made. This easy experiment helps teach kids about one of the most common types of chemical battery call a galvanic cell. Kids will get a hands-on look at making the battery so they understand the concept
Link to literacy with the battery power worksheet (also available in PDF) to find out more about battery research and development from the past to the present day. To take part in investigation 1, each group will need: Understand that batteries are made up of layers of different materials. Understand that batteries store energy.
