The document outlines the key aspects of the scientific method including asking questions, forming hypotheses, designing and running experiments, collecting and analyzing data, and drawing conclusions. It defines important scientific terms like hypothesis, experiment, data, control and experimental groups, and the difference between a hypothesis, theory, and law. The overall process involves making observations, identifying problems or questions, proposing hypotheses, experimentally testing hypotheses, and analyzing results.
Scientific Method Intro
- 1. Science To understand nature through: Observation Finding relationships among pieces of known information ( data )
- 2. Scientific Method An organized way ( process ) to: Study Learn About the world around us
- 3. Scientific Method Involves: Asking questions / Identifying problems Finding answers
- 4. Steps of Process
- 5. Vocabulary Hypothesis : An educated guess Experiment : A way to test hypothesis Data : Information gathered in experiment
- 6. Give Evidence to Support Statements Validity : The experiment tested what it was supposed to test Reliability : If done again, the experiment results will be the same
- 7. Running an Experiment Control Group : group items receive normal treatment (helps us compare) Experimental Group : group items that are tested; they get different treatment Constant Factor ( independent variable ) : parts of the experiment that stay the same Variable Factor ( dependent variable ) : what you are testing; the one part that changes
- 8. Gathered Information (Data) Quantitative Data : involves numbers Qualitative Data : involves a description (5 senses)
- 9. What's the Difference? Hypothesis : based on a FEW observations & NO experimental evidence Theory : based on MANY observations & LOTS of experimental evidence Law : experimentally CONFIRMED & universally stands the test of time without change; used to make true predictions
