what are some models in science?

Question

well my friend is learining about modeling and designing and he has a big quiz tomorrow and he needs some real world models for science. i was wondering if u could help him out

Answer 1

As the term “scientific model” indicates, we are most interested in models from the perspective
of what scientists actually do. And, despite all that makes up or contributes to scientific practice,
the most important overall goal of scientists is the development of an understanding of how
the natural world works. In all scientific disciplines, this understanding is most often
accomplished through the conceptualization of models of various natural processes. It is this
broad goal of science—the conceptualization of process models—that we feel is most important
to convey to students. Other aspects of science may color and no doubt contribute to this overall
goal, but student understanding of this big picture remains for us a primary learning outcome and
provides the focus for the work described at the Modeling for Understanding in Science
Education (MUSE) website.
What is a Scientific Model?
Perhaps the simplest way to begin defining what a scientific model is would be to point out what
it is not. The term “model” is often used to describe (among other things) physical replicas of a Scientific Model.
objects or systems. A space-filling molecular model made of plastic, as well as the material,
globes, and light bulb that make up a “model” of the solar system are examples of a Scientific Model.
