The global battery experiment offers a choice of two investigations, so you can choose the one that best suits you. They have different levels of complexity, and require different equipment, but both offer the opportunity to make your own coin battery. In the process, you’ll learn more about batteries and how they work, as well as getting the chance to practise scientific enquiry skills.
Once you’ve chosen your investigation, you can download the instructions and supporting resources – and get started!
