Conductors and non-conductors with Cobra SMARTsense Code

Principle

Students know from experience that, for example, the wires for electrical cables in the home are surrounded by insulating layers to protect people from dangerously touching live parts. Based on this, metallic and non-metallic materials are to be incorporated into a simple electric circuit and tested for their conductivity.

Tasks

1. Build an open circuit with crocodile clips.
2. Program the Cobra SMARTsense code so that it indicates whether there is a current flow or not by displaying smileys.
3. Investigate which materials conduct electricity and which do not.

Learning objectives

The learners should recognize which substances conduct and which do not. At the same time, they learn how to work with the Cobra SMARTSense code in this experiment.

Benefits

• No additional cable connections required between the components - clearer and faster assembly
• Contact reliability thanks to components that can be interlocked like a puzzle
• Hard gold-plated, corrosion-resistant contacts
• Double learning success: Electrical circuit diagram visible on the top and real components on the bottom
