Some students hold a 'consumer-source' model of the simple circuit
These students may think hat the battery (the 'source') gives something to the bulb (the 'consumer'). They may think, therefore, that a single wire from a battery terminal to a bulb terminal will be sufficient to light the bulb.
The following worksheets may help to identify whether students hold this particular misconception.

- Osborne, R. () Towards Modifying Children's Ideas about Electric Current. Research in Science and Technological Education, 1 (1),
An in-depth interview was conducted with 40 children in the US between the ages of 8 and 12, based on experiments the children were asked to do with electric circuits and pictures of electric circuits shown to them. The researchers concluded that "many different examples need to be discussed if pupils are going to see the wider implications of their new insights" and that making up a circuit with a battery and bulb will not necessarily enable a student to understand how the electric current flows in the circuit.

This study examined the ideas of six lower-secondary science teachers from three different schools of a private education network using a combination of lesson observation, questionnaires and interviews. Four of these teachers held Masters’ degrees (MSc) in the life sciences and two held Bachelors' degrees in Biology and Chemistry. All six had studied physics to an intermediate level (i.e. equivalent of grade 12). Review sheet
