The scientific method consists of four steps:
1. Formulation of a problem2. Observation and experiment3. Interpretation4. Testing the interpretation
The Scientific Method
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
