An example of how a scientist might use a model is by moving the end of a slinky vertically up and down to simulate a wave.
The phenomena that cannot be experienced directly can be described and explained by an idea, an object, or even a process or a system and is called a model in science. Both in research as well as when communicating explanations, models are central to what scientists do.
To explain or predict what may happen in particular circumstances, one or mode model may be proposed by scientists. From providing a way of explaining complex data to presenting as a hypothesis, these are just some of the variety of uses of models.
