Discovering the Parallel Connection's Secrets

 After defining what's an electric circuit and how to construct a simple circuit, it was time to construct an electric connection. Students first constructed series connections, and discovered how electric current have only one pathway and one loop. They have examined what happened if we removed only one lamp or if it's burnt out.. In this lesson i wanted them to be introduced to the second type of connections which is parallel connections. In this lesson students were supposed to be able to construct a parallel circuit and distinguishing it from the series one. They had to examine what happens when a lamp burns or unscrewed. also they had to use different switches in each loop and follow the passage of current. I think it was really so effective to teach this lesson using real experiments and not only diagrams. Students enjoys experiencing such experiments instead of just receiving information.
