What are 2 benefits of using models in science

Models can tell about the consiquences of some exspirements so that we can sort them out. People create a picturistic view in their mind after viewing a model of paticular thing and hence can exsplore it better. 

A model is a representation of something that is too small, too big, or too expensive to observe in real life. So, using this definition, one benefit we can take is that it saves money because you are observing something that may be very expensive in real life but it is actually cheap as a model. Also, it is much safer to use. What if you need to observe an animal. How would you make it stay still? Models make it easier to observe things that are alive too! Hope this helped!
