This paper is concerned with the role of spreadsheets as a tool for the development of mathematical models in science, one aspect of a collaborative project which worked with two groups of pre-university students from Mexico and the United Kingdom. The purpose of the modeling activities designed was to engage students in creating an "artificial world" as a window into a science phenomenon to be explored and studied in detail. The models proposed were a combination of "exploratory" and "expressive" activities. Students constructed spreadsheet models guided by paper-based worksheets. They were asked to construct graphs relating variables of the model and to investigate the effects of varying different parameters, corresponding to different physical situations. It is concluded that the spreadsheet provides the opportunity to connect different mathematical representations and retains aspects of the science problem within the spreadsheet layout, functions, and the representations themselves.
