ABSTRACT
This chapter surveys the important feature of science that relates to experimentation in interesting ways: the use of models. To uncover the roles that models play in science and to see how the Bay Model in particular works, the chapter focuses on why that model was originally constructed. The Bay Model is not just a toy model, however. It's a scientific model, and this has some important implications. Building a model of a phenomenon is kind of like taking apart a toaster and putting it back together again. A great way to learn about something is to try to build it, or something that's like it. Physical models might literally be built; other kinds of models, like equations and computer programs, are also built, only in a more metaphorical way. While the Bay Model is a scaled-down representation, other scale models are enlarged representations of their targets.
