Modelling in Science

Scientific modelling is a scientific activity, the aim of which is to make a particular part or feature of the world easier to understand, define, quantify, visualize, or simulate by referencing it to existing and usually commonly accepted knowledge. This particular video exemplifies the concept of using 'Systems and Models' in science.

This idea is not new, but it gives some clarification to the idea of employing them when needed, in order to convey a more overarching concept, such as the word 'Ecosystem' is very complex. It includes many subsystems that can be modeled as well. One concept is the 'Food-web', but where does the food-web begin and where does it end? This is a question that can be posed to students. As well as 'the weather' created by wetlands. Or impacts upon wetlands from outside systems from human developments within wetlands for example.

Having students draw out their own particular aspect of an ecosystem, then coming together to share their insights into each aspect of the wetland can culminate in unique learning opportunities that are only accessible through modeling.Employing SLC’s (Student Learning Communities) allow students to work collaboratively. Designating work assignments within SLC groups, each independently researching one aspect of a chosen model. Group members work to assemble each aspect of the model into a completed model which is then presented to the rest of the class. Learning also take place as SLC’s instruct other students about their specifically developed models
