Suggestions for use: 
Divide the class into small groups of 24 students and hand out the worksheet: Electric current, battery and bulb. The students working in groups go step by step from simple observation to guided discovery up to bounded inquiry. Let students play in groups with a torch and dismantle and examine its components. Students should identify three basic components: a switch, a bulb and a battery that are connected in series. They learn that for current to flow the closed circuit is needed. The torch case can be a part of the circuit. After this first simple investigation they learn to build their own simple electric circuit from a battery, a bulb, leads and a switch. Students should work on their own realizing bounded inquiry. Once they have completed the investigation they summarize the results and present them to the other groups. In case we do not have all materials for each group or we are lack of time, each group can construct one of the suggested electric circuits.
