1 The Scientific Methoda series of logical steps to follow in order to solve a problemno right or wrong way, as long as it is logicalusual stepsObserveQuestionResearchHypothesizeExperimentAnalyzeConclude
2 Observe simple things you notice in nature Newton noticed things fall to the ground.Darwin noticed some creatures survive better.Fleming noticed bacteria wouldn’t grow around the mold.Carver noticed nitrogen content in the soil is higher around some legumes (peanuts).
3 Question decide what you want to know why do things fall? why do they survive?why won’t the bacteria grow?why is the nitrogen content higher?
4 Research gather everything already known commonly known information experiments done by othersdocumented observations
5 Hypothesize predict an answer to your question usually and “if ______, then _____” statement“If all objects fall to earth at the same rate, then some constant force is pulling on them.”
6 Experiment plan a carefully controlled experiment determine your variablevariable - anything that can change in an experimenta good experiment has only ONE variabledocument your plandocument your equipmentperform the experimentRECORD your detailed observationswhat changed? what didn’t?measurements where appropriate
7 Analyze organize your data create tables or graphs if appropriate does the data support your hypothesis?if yes, do the experiment again to gain further evidenceif no, do the experiment again to check for mistakesstill no? rethink your hypothesis
8 Conclude summarize what you have learned detail what your observations and data told youexplain what this information means and how it supports or denies your hypothesisinclude ideas for new experiments to
9 Failure or Success? NO experiment is a failure! even if our hypothesis is proved wrong, we have still learned somethingdiscoveries from “failed” experimentsNorth Americapenicillin
