Why Use a Model?
Modelling is used by scientists to describe reality. Types of models are used by; a) economists to depict factors involved in the rise and fall of unemployment and the stock exchange, b) NASA engineers to depict the trajectory of a rocket to the moon, and c) architects to depict how thick the insulation should be in a house. There are lots of different types of models used in science which all use their own "language" to show science phenomena. The type of modelling you'll be working with is called "systems dynamic modelling".
Modelling often helps scientists to predict outcomes from various scientific phenomena. For example, a meteorologist creates models of the weather in order to make predictions for the evening newscast. This kind of modeling is not static. A meteorologist will continually refine and change their models based on up-to-date information in order to make their predictions more accurate.
To help you learn more about systems dynamic models, you’ll complete the “Introduction to the Model Editor” packet. This instruction will teach you how to use the model editor tool in Co-Lab to make a model of a bank account and to help you predict when you’ll be able to afford a DVD recorder. Begin by opening your packet and going to the theory room.
