In empirical modelling, the focus is on the use of data to construct a model, usually in the form of a formula or equation which best fits the data. Five modelling activities will be discussed in this chapter, namely, the use of footprints in police work, water sustainability in Singapore, the growth of bread mould, the use of mathematics in a relay race, and the location for a pedestrian crossing. Each of these activities will have a clearly defined task, along with a description of the problem situation, followed by notes for teachers. An approach to each task will be examined, as well as the use of a modelling framework in planning the activity. Each activity concludes with suggestions for discussion points with students.
