3 Experiment vs. Demonstration SCIENCE EXPERIMENTSCIENCE DEMONSTRATIONUsually more involved and in most real experiments you compare results.An example would be "What fertilizer works best on plants?" or "What is the strongest brand of paper towel?" In these examples, you ask a question and then perform experiments to get the answer.is a quick little science "show" that explains a science concept like building a model volcano and watching it erupt.It shows how something works, but it is not a true experiment.
4 Scientific Method Checklist ___ 1. Base your idea for an experiment on an observation___ 2. State your purpose. Usually the purpose of an experiment is stated in the form of a research question___ 3. Perform background research to find out what is already known about your topic___ 4. State your hypothesis, a possible answer to a research question___ 5. Design a detailed procedure, or list of steps
5 Scientific Method Checklist Cont. ____ 6. Carry out your experiment and collect data____ 7. Record your results on a data table. Construct a graph of the data you collected (bar graph, line graph, pie graph, pictograph).____ 8. Write about your results explaining your data.____ 9. Draw a conclusion from your results. Discuss your data and what it means. Did your hypothesis prove true? What did you learn? Were there any possible errors? How could you improve this experiment next time or what could you do next?
6 Scientific Method: Words to Know Variables: Characteristics in an experiment that change or could be changedIndependent Variable: Factor that you change on purpose; also called the manipulated variableDependent Variable: Factor that you observe or measure in response to a change in the independent variable; also called the responding variableHypothesis: Possible explanation for a set of observations or an answer to a scientific question; must be testable
7 Scientific Method: Words to Know Cont. Constants: Characteristics in an experiment that are kept unchanged in all trialsControl: Standards to which you will compare your resultsTrials: Number of times an experiment is repeated for each level, or value, of the independent variable. The more trials, the more reliable your results
8 Key Points to Remember Students must measure something All measurements must be made using the metric systemMeters, Liters, Grams, Time, Temp, TallyMinimum of Three Trials per experiment; the more trials you have the more reliable the data will beAll Science Back Boards have been purchased and will be distributed at a later date
