MODELS
are representations of real objects, systems, or ideas.
Scientific models can be classified into three categories…
Physical

3. PHYSICAL MODELS can be touched, manipulated, etc.
often “scaled” to the real thing
usually used to explain or describe things, to help visualize
Examples
human body plastic torso
model planes, cars, rockets
solar system model

4. MATHEMATICAL MODELS
mathematical equations that describe the behavior of a system
often used to predict what will happen if…
also called “computer models”
Examples
weather forecasting models
astronomy models

5. CONCEPTUAL MODELS organized ideas about how something works
used to understand something
Examples
how gravity works
blueprints for a building
Earth is made of layers – crust, mantle, core
how the solar system moves

6. Why use MODELS?
Real things might be too big, too small, too complicated, too far away, etc. to study directly!
Scientific models can…
help explain how things work
help people visualize things
make predictions - what will happen?
Models are limited…
only as good as the data that went into creating them, must be TESTED
