Math + ScienceVery Powerful Combination Math + ScienceVery Powerful CombinationUnderstand RelationshipsThe Scientific MethodA Classic ToolChapter 1Part 3Scientific MethodAn orderly method for gaining, organizing, and applying new knowledge.Scientific Method1. Observe (what do you see?) andQuestion (recognize a question or problem)

Scientific Method2. HypothesizeMake an educated, testable guess (hypothesis)to answer the question

Scientific Method3. PredictWhat will happen if the hypothesis is correct?

Scientific Method4. Test the PredictionExperiment Are the predicted consequencespresent?Scientific Method5. Draw a ConclusionMake a simplified statement that summarizes the process and resultsScientific MethodForm a ConclusionOrange - wrongLime- correctObservationA paper bag is on a counter - what is in it?

Revise the HypothesisLimeScientific HypothesisTestableThere is a test for proving it right

More important to be capable of being proven wrong! Lets go back to GalileoHis experimentation led to modern scientific practice.

Facts, Theories and LawsThey arent what you think they are.FactSomething that observers agree is true.It is testable.Not necessarily absoluteFor example..Fact Salamanders are able to regenerate limbs.

Unfortunately, humans are unable to regenerate limbs.

TheoryCollection of facts and well tested hypotheses.Continuously grow stronger and more precise with new information.
