Graphite Conductor Science Experiment

Science experiments are the best tools for making a kid understand science in an interesting manner. These science experiments are simple to carry out and involve use of daily household items which are easily available at our home. A child can select any idea from the huge variety of science experiments and conduct an experiment on his own as per the instructions.

While performing these science experiments an adult supervision is the must because some of the science experiments may involve the use of materials or equipments which can cause injury incase not handled with care. The Graphite Conductor science experiment is one of the most popular science experiments. In this article we are going to discuss about how to make a cool Graphite Conductor.

Why Graphite is a good conductor of Electricity :

To perform this Graphite Conductor science experiment all you need is a pencil with graphite lead, battery, scissors and a small bulb. Firsts of all take the bulb and attach it on the top end of the pencil in such a manner that the base of bulb touches the graphite lead in the pencil. Now take a battery and touch the tip of pencil lead on the shorter tongue of battery.

To complete the circuit you will need to take a scissor and touch any one of its pointed parts on the longer tongue of battery and the other pointed part to the middle of the bulb. Soon you will see that the bulb lights up.

This happens because as soon as the circuit is completed the current flows form the negative pole (longer tongue of battery) through the metallic scissor to the bulb and then through the graphite lead to the positive pole (shorter tongue) of battery making the bulb to glow immediately.

You might have observed that the Graphite Conductor science experiment is pretty simple to carry out and does not require much effort at all. Kids can try this science experiment at their home and find it pretty amusing.
