  1. Scientific Inquiry Investigation Scientific Method

  2. as an inquiry question ???? 1. State the problem • What is the effect of__________ (independent variable -manipulated factor) • on_________ (dependent variable -responding factor that is observed and measured)?

  3. Ex. What is the effect of acid rain (I) on limestone (D)? • Ex. What is the effect of light (I) on Sow bugs (D)?

  4. How do you come up with the questions?

  5. 2. Form a hypothesis • An educated guess • Prediction • If ________ (independent variable), then _________ (dependent variable). • Ex. IfI leave a popsicle out in the sun, thenit will melt.

  6. Explain what led you to choose the topic and question. • Why do you think your hypothesis is correct? • What do you already know about the topic and question that helped you form your hypothesis? 3. Background Information

  7. Background Information (cont.) • What have you researched that tells you your hypothesis is correct. • Did you use your five senses?

  8. 4. Procedure • Materials: what is needed to do the experiment? Include amounts. • Step-by-step instructions List in step-by-step order what needs to be done to perform experiment and test hypothesis (be specific!).

  9. Procedure (cont.) • Multiple trials to get accurate and valid data. • Control variable-factor that never changes during an experiment. • Ex. If you wanted to know how the sun affects the ripeness of grapes, you would need two set-ups.

  10. 5. Record/Organize Data • Qualitative: observations of behaviors using 5 senses or conducting surveys over time. • Quantitative: measurements displayed in tables, graphs, charts, diagrams, drawings. • Use correct units • Use totals/averages

  11. Record/OrganizeData (Cont.) • Daily Recording- need a journal notebook to record everything done before, during, and after each run of the experiment.

  12. 6. Conclusion (paragraph form and complete sentences) • State whether your hypothesis is correct or not based on results • The data does/does not support my hypothesis. • Explain how the results/observations support hypothesis- use data!!

  13. Conclusion (cont.) • Explain the scientific concept of your scientific inquiry. • The results show that________ because________. • Any errors/problems that may have affected your results? How can the experiment be done differently? • Is there a different independent variable that you could test?
