BIO 1100 1St week of notes This is a supplement to the handout in class The Scientific Method Science is a method of thinking about the world We all have a philosophy Our consciousness leads to the fact that we have our own philosophy know the definitions in the class handout The Steps to the Scientific Method 1 It all starts with an observation 0 Uses induction I Going from a specific situation to concluding a general statement 0 has to be confirmed with other literature available aka research 2 Form a testable hypothesis 0 Hypothesis an explanation of a phenomena NOT a prediction I Hypotheses are used to make predictions 0 quotA hypothesis that cannot be mortally endangered cannot be alive Trevor Platt 1964 I Basically saying if a hypothesis is not testable it s useless 0 However hypotheses may be testable but there might not be technology to test it I Hypotheses like these may be retested at later times I Example Mutations in DNA may be the cause for certain birth defects 0 This hypothesis was brought up before scientists had the ability to examine DNA 0 However it was later tested when the technology was available 3Define dependent independent and controlled variables I Dependent must be distinguished between the different hypotheses I Independent must be completely unchanged during the experient I Controlled other traits that are not being tested but may affect the results of the experiment 0 It is best in an experiment if all participants were as similar as possible in order to get the best test results 0 Example using only men between the ages of 3035 with perfect health and no history of smoking or alcohol abuse 4 Use the hypothesisamp variables to make a prediction 0 Be sure to include a null hypothesis I An explanation that completely refutes your observation at hand I Example Alcohol abuse tends to lead to family abuse 0 Hypothesis alcohol contains a chemical that may trigger a hostile reaction towards others 0 Null Hypothesis alcohol has no connection to family abuse 5 Find people to test it your experiment 0 Be aware amp ready to deal with unknown problems or complications that may happen during the experiment I Example participants experience unexpected reactions deaths and etc 6 Go Do It 7 Analyze the results 0 May require the use of statistics 0 PValue the value that calculates how big the chances are of an experiment s results being completely by chance I lt005 Not likely at all of it being by chance I gt005 Likely enough that it could be by chance 0 If this is the PValue the null hypothesis is still a possibility
