  1. Scientific Method Lab Mapping

  2. Title • Informative • Not “cutesy” or “advertisement-y” • Includes important information on the subject of experiment

  3. Problem • The research question is the single most important part of the scientific method. • Every part of your project is done to answer this question. • The research question is sometimes formed as a statement.

  4. Hypothesis • proposed scientific explanation for a set of observations • A reasonable explanation supported by observation and/or research • In class, written in an “if, then” statement • Does not always appear in the “if, then” format

  5. Independent Variable • “I the scientist changed this.” • Manipulated variable • Purposely changed • Experimental variable • what you test on the experimental group to see if makes a difference

  6. Dependent Variable • What is being measured during the experiment. • Data • Results of experiment

  7. Controlled Variables • Constants of experiment • What you keep the same so you can isolate and test a single (1) variable.

  8. Experimental Group • Group tested on • a set of items or people under study to determine the effect of an event, a substance, or a technique • the group of participants in a clinical study who receive the actual drug or treatment being studied

  9. Control Group • The group of participants in a clinical study who do not receive the drug or treatment • Can be given placebos • practically identical to the experimental group, although the experimental group is changed according to ONE (1) key variable of interest

  10. Procedure • The procedure is a somewhat detailed, step - by - step description of how you conducted your experiment.

  11. Qualitative Data • “quality” means good/useful • This is data you collect through observations using your 5 senses. • Subjective

  12. Quantitative Data • “quantity” means numbers (#) • This is numerical data you collect during experiments.

  13. Graph • Picture of data • Line, bar, circle/pie • Visually represents data • Helps to see patterns, relationships, or trends

  14. Analysis • Examine and explain the data • the section in which you interpret your results • what happened and WHY! • if data does not support your hypothesis at all, you may explain why the results were different

  15. Conclusion • statement of whether your data supported your hypothesis or not • Outcome as related to the data and the hypothesis
