Ideas to Understand : Ideas to Understand Scientific “Laws”
Describe relationships

Ideas to Understand : Ideas to Understand Certainty in Science
Limited by the method of observation and the skill of the person who made it.
Speculation
A guess
Causality
A direct cause and effect between two events is demonstrated.
Correlation
A statistical relationship exists between events.
Regarding the Scientific Method : Regarding the Scientific Method A hypothesis can be tested. (Design an experiment to . . . . )
A speculation cannot be tested
When several hypothesis have been successfully tested, the grouping of related successful hypothesis may be grouped into a scientific theory
When the theory is used to predict new phenomenon then it may, over time, become a scientific law
Two events may have a very strong correlation yet they are completely independent (not related)
