Scientific Models and Theories

What is a Model? A representation of an object or system A substitute for what you are studying Used to explain the structure of something and
how it works Used to make predictions and explain
observations

3 Types of Models Physical Models
Mathematical Models
Conceptual Models

Physical Model Looks like the thing they model
Example: toy airplane

Mathematical Model Made up of numbers, equations,
and other data.
Example: Punnett square

Conceptual Model Represents system of ideas
Example: Cell Theory- all living things are made up of cells

Benefits and Limitations Benefits:
Used to represent things that are otherwise too small or too large
Can be a hypothesis and tested Limitations:
It is never exactly like the real thing It can only tell us what our current
scientific knowledge tells us

Theories A Theory is a scientific explanation
that connects and explains many tests/observations.
Used to explain and predict situations
It is a conceptual model

Theories cont. Scientists are always discovering
new information. This new information may show
that a theory is incorrect. When this happens, the theory
must be changed so that it explains the new information.
