Scientific Inquiry
• Gather data• Formulate plausible explanations• Devise tests and predictions• Revise, reject or accept explanations

Hypothesis vs. Theory
• Hypothesis is an explanation that requires testing
• Theory has been tested, and is supported by the evidence, and predicts things not used to formulate the hypothesis
• Paradigm is a theory that explains wide ranging sets of observations

Nebular Hypothesis
• Formed our solar system– Sun– Planets– Asteroids and comets
• Rotating cloud of dust and gases collapses into these bodies
