The generation of electrical power is one of the basic needs for maintaining our lifestyle. For this purpose many science projects keep trying to find more efficient ways of power generation and utilization. Alternative sources of power generation are big business today as the traditionally used fossil fuels are just not going to last much longer.

To this effect any science fair project dealing with energy generation will be an eye catching one for the judges. Toss in an unlikely method of generating energy and you may even have a prize winning project. For our project of a fruit powered battery we are going to use a simple circuit with a multi meter that can measure low voltages.

Add alligator clips to the circuit to be attached to the fruit and collect a basket of different types of fruit. You can even add a small light to the circuit to see if it can be lit at the voltage produced.  Now we are ready to record which fruit is the best producer of electricity. Keep detailed records for the power production of each fruit that you use.

You can use the data collected in a tabular form on your display board. Also have the fresh fruit handy for the judges to use on the circuit. Remember each fruit will be used just once. Have fun playing with your science fair project.
