Hypothesis

(Parsimony)

3. SCIENTIFIC LAWS
based on repeated experimental observations describing some aspects of the universe.
Applies under same conditions
Implies causal relationship
EQUATION

4. Example Law of Gravitational Force: represented by an equation
F = G × [(m1m2)/r²]F = G × [(m1m2)/r²]
Kepler’s Law of Planetary Motion

6. THEORY A Principle supported by evidence – lots and lots includes
Factual evidence, proven hypothesis, laws of nature
Theory never becomes a law- have separate roles in science – a law can strengthen a theory

7. Examples of Theory Big Bang Theory Theory of heliocentricism
