Batteries we use are mostly what we describe as 'dry cells' some batteries, e.g. car batteries are 'wet cells'. Both work using the same principles.

Look at the example worksheet for investigating. Read through it and use the information to design your own investigation.

Important point to remember:
 * to ask lots of questions before you start your design
 * if you find that your investigation isn't working, change it
 * if you finish early and want to extend your investigation, do so
 * **refer to the Investigations guidelines and advice when designing and writing up your report**
