The Scientific Method
The scientific method consists of four steps:
1. Formulation of a problem
2. Observation and experiment
3. Interpretation
4. Testing the interpretation
Hypothesis-an initial scientific interpretation.
Law-a relationship or regularity between naturally
occurring phenomena.
Theory-Explains why a phenomenon or a set of
phenomena occurs.
Models-to simplify complex situations
