Conductors and non-conductors

Principle

The students know from experience at home, for example, that the wires for electrical connections are covered with a layer of insulating material to protect people using the electrical devices from the danger of touching "live" parts. With this as the basis, metallic and non-metallic materials are to be connected in a simple circuit and their conductivity tested.

Benefits

• No additional cable connections between the building blocks needed - clear arragned and quick setup
• Contact saftey due to puzzle blocks system
• Corrosion-free gold plated contacts
• Doubled earning sucess: Electric circuit diagram on top, real components can be seen unterside
