How do scientists use models?
Why are models important?
Elaborate
A Scientists needs your help! He is studying about the bones in the human body and how they are connected! He has never studied this before and he is not a doctor so he does not have the access to to view real human bones! What would you tell this scientists that he needs to do? Explain how a model would help him with his research.

What is a Model?
Types of Models
Big Models vs. Small Models
A model can be an object, diagram, or computer program that represents something that a scientist is studying
How do Scientist use Models?
Scientists use models in many ways :
to help them understand the natural world
to communicate their ideas
to understand processes
to look for patterns
to make predictions
to help make something simpler or easier to see
to explain how things work
Physical model: a physical representation, such as a small version of a large object
Two-dimensional model: a drawing or diagram of an object or a process
Computer model: a wide array of representations made using a computer
Scientist can use models to view objects or processes that are either too large or too small to see just by looking at it
Big Models
Small Models
Water Cycle
Solar System
Plant Cell
Animal Cell
What is this a model of?
Describe what is shown in the model.
How is the model helpful for scientist?
