  1. Scientific Method

  2. Scientific Method State the Question Collect Information (research) Form Hypothesis Test Hypothesis (Experiment) Record and Analyze Data Draw Conclusions Types of Variables

  3. (Top Flap)A way to ask and answer scientific questions, by making observations and doing experiments. • How, what, when, who, which, why or where. • Start with a question. • Something that you can measure, preferably with a number _________________________________________________________________________ State the Question

  4. Look it up! • Look up information on the internet, in books, magazines, & past projects 1. Identify key words in the question. 2. Brainstorm keywords & concepts. 3. Know & learn about concepts Research helps you understand your project! Collect Information

  5. I believe that, if (IV), then (DV-trend) . I base my hypothesis on these facts. 1. 2. 3. (may be personal) Form Hypothesis

  6. Materials- list of materials and equipmentProcedure- what steps were taken while doing the experiment________________________________________________________ Your experiment test • Whether your hypothesis is true or false, It is important for experiments to be a fair test. • Change only one factor at a time, while keeping all other conditions the same. Repeatiftime! Test Hypothesis

  7. Once experiment is complete, collect measurements & analyze them to see if the hypothesis is supported or not. • Make sure to label all graphs and tables. • Include units of measurement. • Use graphs/tables and/or charts to show data. Record & Analyze Data

  8. Summarize how your results support or contradict your original hypothesis. • Write in complete sentences. • Support conclusion, include key facts from research. • State whether results support or contradict the hypothesis. • Summarize & evaluate experiment • Suggest changes in experiment procedure for further study. Draw Conclusion

  9. Putting on the Graph (top flap) Dependent R Y-axis M Independent X- axis

  10. Variable- any factor; trait; or condition that exists in differing amounts or types. • Independent variable- one variable that is changed. (I Change it) • Dependent Variable- how it responds to the change made by the independent variable. • Controlled Variable- remains constant Types of Variables
