8th Grade Scientific Method Review 1. Ask Question Ask a question to find out more information or to solve a problem. What does this fossil show? What kind of medicine will cure a disease? 2. Do Background Research Find as much information on the problem or question as possible. You may be able to answer your question with simple research and avoid an lengthy experiment! 3. Construct Hypothesis An explanation based on limited information. Must be further researched to determine its accuracy or truthfulness. 4. Test with Experiment Construct a measurable experiment Collect Data: Information such as numbers, images, or words, gathered in an experiment. 5. Analyze Results/Draw Conclusions Conclusion - The result of an experiment, action, or process. 6a. Hypothesis True? Report Results Show Data, graphs etc. Write explanation Report - A well-written scientific paper containing a hypothesis, explanation of experiment, all gathered data, and a conclusion of results. 6b. Hypothesis False? Still report results! Go back through the method and try again! Report - A well-written scientific paper containing a hypothesis, explanation of experiment, all gathered data, and a conclusion of results. Test Vocabulary Calculate Do a mathematical equation Rate, Speed, Velocity Speed=distance/time How fast something is moving Observation The act of noting or observing something. Observations are always recorded. Hypothesis An explanation based on limited information. Must be further researched to determine its accuracy or truthfulness. Variables Variable - An aspect of an experiment that changes. Independent variable: The variable controlled. Dependent variable: The variable that is measured. Data Information such as numbers, images, or words, gathered in an experiment. Scientific Theory An explanation of natural phenomena. Scientific theories are supported by facts, observations, and repeatable experimentation. These theories may change as technology advances and better observations are made. Examples: Cell Theory, Theory of Plate Tectonics, Gravitational Theory Density Density=mass/volume Mass The amount of matter in an object Volume The space taken up by an object, liquid, or gas Time How long an event is Seconds, minutes, or hours Correlate, Correlation What is the correlation between gravity and mass? Or, What is the relationship between gravity and mass? How do two things effect one another Heterotroph, Consumer Heterotroph – cannot make its own food Consumes other organisms for energy Autotroph, Producer Can produce its own food Consumes food that it has produced itself Decomposer Breaks down dead or dying organisms MCA Practice Questions Earth and Space Science 1 http://regentsprep.org/Regents/core/questions/qu
