  1. Scientific MethodMIQ’s Why do scientists follow the scientific method? What are the steps to the Scientific method? How can I remember the steps in order?

  2. Problem • Step 1 • This is what we want an answer for.

  3. Problem continued. • This must be a question. • It must include a question mark. ???

  4. Research • Step 2 • Information to help answer questions. • Also called background research. • This can be “bookwork” (or internet) or it can be lab or field observations(real world stuff…remember that?

  5. Research cont. • Start by outlining the experiment and doing an experimental design diagram. • Determine the controls and variables. Controls or constants are the things that are kept the same throughout the experiment.

  6. Research cont. • The variables are the things that you change or that change because of the experiment.

  7. Hypothesis • Step 3 • This is called a predication as to how one variable will affect another. • It is often written as and if…then statement.

  8. Experiment • Step 4 • Here’s where the fun begins. • This is the process of setting up a controlled situation to support your hypothesis.

  9. Experiment cont. • Determine what data you have to collect and design a data table to support (or refute) the hypothesis. • Data should be specifically measurable. This means you observe, AND record color, height, weight, etc (###)

  10. Experiment cont.Dependent and Independent Variables • The independent variable is the one you (the experimenter) determines. • It is sometimes called the manipulated variable.

  11. Experimental variables cont. • The dependent variable is what changes as the result of the experiment. • Both variables should have columns in a data table.

  12. Analysis • Step 5 • Graph, graph, graph • What does the data show you?

  13. Analysis cont. • Did the independent variable cause the change in the dependent variable? • So to simplify…analyzing results means look at the data what does it tell you?

  14. Conclusion • Using the data and the graph generated, answer the question that was originally asked. • Always refer to the data and the hypothesis when writing the conclusion.

  15. Report results in writing • Include all of the above in a standard format that demonstrates a clear connection between independent and dependent variables.

  16. Report cont. • Note all possible errors and biases. • What are further hypotheses or experiments to further support this one?
