This article recounts the author's working experience of one method by which pupils' understanding of the epistemologies of science can be developed, specifically how scientists can develop hypothetical models and test them through simulations. She currently uses this approach for transition lessons with pupils in upper primary or lower secondary…

Presents examples that illustrate how spreadsheets can be used to ask and answer all sorts of scientific questions given suitable automation of useful spreadsheet procedures. Examples include data exploration, data analysis, project presentation, simulations, and students writing their own models. (Author/JRH)

Presents a numerical simulation of a simple food chain together with a set of mathematical rules generalizing the model to a food web of any complexity. Discusses some of the model's interesting features and its use by students. (Author/JRH)

States that constructive thinking about variables seems to be a key to accelerated learning in science and that computer modeling can enable this. A taped sequence of a group in the exploratory use of a model reveals the potential of such activity. (Author/ASK)
