Why are models important ?
Answers
Explanation:
Models are important in science because a model is a representation of an idea or an object or systems that could be used to describe something that cannot be experienced directly
Answer:
Models allow the scientist to describe objects that are too large or too small to be seen normally, things that don't exist anymore, things that have not been created, and events that occur too slowly or too quickly to be seen. Models also communicate ideas that might be difficult to describe otherwise.
