Conductivity Experiment
Recommended Age: 3y+
Description
Electricity is the most versatile energy source that we have. Lights, computers, heaters, telephones and even cars are all powered by electricity. This Learning Board teaches us that for electricity to flow around any circuit, a complete conductive loop is required from the power source through the output device and back to the power source. As a demonstration of this, a circuit containing a light bulb and 4 switches allows children to bridge the gap using everyday objects. If they press the button with a conductor in place the light bulb will light up. If they select a button with a non-conductor the light bulb will not light up. The human body is resistant to current, but it does permit a small current to flow through it. Using the board children can bridge an open circuit using their hands and it will light a bulb. They will not feel any electricity flowing through them because the current is so small.
