This is one of a set of resources developed to support the teaching of the primary national curriculum. They are designed to support the delivery of key topics within science and design and technology. This resource focusses on the use of fruit to power a light emitting diode (LED).

Did you know that fruit can be used to produce electricity? Connecting four lemons in series can provide enough voltage to light an LED! This also helps us to understand how batteries work.

In this activity learners will construct a series circuit consisting of four fruit batteries and an LED. They will learn about the main parts of a battery and how fruit can be used to provide enough voltage to light an LED. They will also investigate how the brightness of the LED changes depending on the number of fruit batteries used in the circuit.
