In most South African schools Grade 12 Physical Sciences learners are generally not performing well. As Examiners’ Reports reveal, they are particularly weak on the topic of electrical circuits. Because of this, the Examiners recommended that conventional practical activities and revision should be implemented to improve learners’ performance whilst they are in Grade 11. These factors contributed to the rationale of this study in using the ‘straw electricity’ analogy in conjunction with a conventional practical activity to mediate learners’ sense making of Ohm’s law. The study falls within the interpretive paradigm, whose focus is on the understanding of human world-views. Within the interpretive paradigm a qualitative case study approach was employed. It is a case study because it aimed to investigate a group of learners in a given context. This qualitative case study used purposive sampling to select participants. Various data gathering techniques were employed, namely, documents, observations and stimulated recall interviews. The gathered data was analysed so as to determine the indicators of how learners made sense of Ohm’s law. The findings of this study are that learners were able to construct new knowledge within a social context where the ‘straw electricity’ analogy, using easily accessible resources, was incorporated in tandem with a conventional practical classroom task. Moreover, the ‘straw electricity’ analogy enabled a better understanding of science concepts as it tested and supported different learning skills.
