4. Scientific Laws and Theories
Laws- a law allows predictions to be made. It describes a process in nature that can be tested by repeated experiments. DOES NOT EXPLAIN HOW!
Theories- are always being questioned. To be valid it must pass several tests.
1) Explain clearly and consitently
2) experiments must be repeatable
3) Must be able to predict from the theory.

5. Math can describe physical events
Area of a rectangle:
A = l x w
Gravitational equation
F = g m1xm2/d2

6. Models: Represent Physical Events
Water
Crashes

7. Computer Models
Weather
