11. Define the problem by OBSERVING. The Scientific Method1. Define the problem by OBSERVING.a. Make observations by using the 5 senses to perceive objects/events.b. Collect DATA by measuring (qualitative/quantitative data) & samplingc. Organize the data collected
22. Form a testable HYPOTHESIS Scientific Method2. Form a testable HYPOTHESISa. PREDICTION-statement made in advance that states what the results are believed to be when the hypothesis is tested and supported1. “If…then…” statements
33. Design EXPERIMENT –testing hypothesis Scientific Method3. Design EXPERIMENT –testing hypothesisa. Test only 1 variable – INDEPENDENT variable (which drives the dependent variable)b. CONTROL for other variables
44. Experiment – Record DATA Scientific Method4. Experiment – Record DATAa. observingb. measuringc. samplingd. Organize data – usually data table
5Scientific Method5. Analyze Data – Draw CONCLUSIONSa. Make a graph or some visible representation of the datab. Has your hypothesis been supported?c. INFERENCE-conclusion made on basis of facts rather than observations
6a. This may be done by publishing the work completed. Scientific Method6. Report Findingsa. This may be done by publishing the work completed.b. THEORIES may be formed after many related hypotheses have been tested and supported with much experimental evidence.
7Do Now!Why is it important that scientists use the same procedures to conduct their research?
