Electricity is the most versatile energy source. Lights, fans, computers, and most other electrical appliances are powered by electric current. For an electric current to happen, there must be a circuit.
 
A circuit is a closed path or loop around which an electric current flows. This Conductivity Experiment wall panel comes with two electric circuits. The circuit on the upper part is still open, requiring children to make it a closed circuit by pressing one of the four buttons.
 
Each button represents 1 type of material of different conductivity. If plastic or tile is chosen, the light won't be turned on because electric current cannot pass through insulating materials. Another circuit is also an open circuit.
 
Children will be asked to use their bodies as connectors to make it a closed circuit. When a child puts both hands on the panel, the light will turn on! Children will be amazed by this phenomenon. Teaching them human bodies are electric conductive cannot be easier.
 
Please Note: Wall Elements can be placed on a table but are Specifically Designed to work with our STEMWALL.
