2. A. Emonds I. Jansen THE LIVING ELECTRIC CIRCUIT

3. Working in projects 50% = basis skills 50% = understanding (being able to explain) + justifying the topics.

4. What can we expect ? Understand terms such as: Basic skills Tracing errors in electric circuits Reflect Is what we make justified and safe for society? *Conductor/ isolator *Electric circuit: open or closed * Security 50 %

9. How can this be?

11. The primary circuit is interrupted.

12. Pupils learn and discover while they play open and closed electric circuit; how to trace errors in an electric circuit; the pupils discover that the human body is a good electric conductor; terms such as conductor and isolator; safe electric installations are necessary. terms such as voltage and electric current;

13. GOOD LUCK !
