  1. Scientific Method • Observation/Research/Problem • Hypothesis • Experimentation • Collection of data • Analysis and conclusion • Repeat

  2. Problem:Always the toughest part!! • Written in the form of a question. • All research will be focused on finding an answer to the question. • The Answer to the problem should have only one answer, for example, • Yes/No • Greater/Lesser

  3. Hypothesis • Written as an “IF…… THEN…” statement. For example: • If plants are denied light for two months than they will die. • If: the action of the experiment • Then: the results of the experiment

  4. Experimentation: • The experiment must be a controlled experiment. -Control group (Compare results to) -At least one experimental group (contains the experimental variable) • There should be at least 10 subjects in each group or it should be repeated on one subject 10 times.

  5. DATA: • Rough/Raw: • This is disorganized lists, sketches… • Smooth: • Data for each group is displayed separately in graphs and tables • Analyzed: • Graphs and tables that compare your experimental group with your control group

  6. Analysis and Conclusion • These are often found together. • Conclusion: • Based on experimental results the hypothesis is accepted/rejected. • Analysis: • Brief discussion of results and why they lead you to accept or reject the hypothesis
