Introduction

Introduction to “Just How Small is the Atom”

Scientists use models (smaller or larger versions) of things to be able to study them better.  Cells for instance are really small, it would be difficult to study the nucleus at the size it is.  Our solar system is really huge, therefore it would be difficult to study Saturn at the size it is. 

So, scientists use models to manipulate or study things much more easily.

There are advantages and limitations to models.  For instance, you want to build a Corvette, but you obviously don’t drive, so the next best thing would be for you to build a model, a scale model (all parts of the car are accurate, but way smaller).  The advantage is that you now have a Corvette and is an exact, yet smaller, replica.  But a limitation would be that you can’t drive it.  

So think about ways that scientists use models, and what are the limitations and advantages of using models...
