Year 8 – Lighting up bulbs with lemons!

This week 8G were given the task to light up a bulb using a lemon as a power source. After talking about how electricity is generated they inserted pieces of both zinc and copper into the lemon and made a circuit. The bulbs did not light up! By adding a voltmeter to the circuit they saw that the lemon juice had conducted the electricity from the zinc to the copper but there was not enough produced to light the bulb. They were then challenged to come up with an idea of how they could light the bulb by working as a class. As you can see, they clearly are bright sparks!  Mrs Thompson

Some girls even went on to experiment with grapefruit and oranges.
