  • Scientific Inquiry Investigation

    Scientific Method

  • 1. State the problem

    as an inquiry question ????

    What is the effect of __________ (independent variable -manipulated factor) on _________ (dependent variable -responding factor that is observed and measured)?

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

    Ex. What is the effect of light (I) on Sow bugs (D)?

  • How do you come up with the questions?

  • An educated guessPredictionIf ________ (independent variable), then _________ (dependent variable).

    Ex. If I leave a popsicle out in the sun, then it will melt.

    2. Form a hypothesis

  • 3. Background Information

    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?

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

  • 4. Procedure Materials: what is needed to do the experiment? Include amounts.

    Step-by-step instructionsList in step-by-step order what needs to be done to perform experiment and test hypothesis (be specific!).

  • 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.

  • Qualitative: observations of behaviors using 5 senses or conducting surveys over time.Quantitative: measurements displayed in tables, graphs, charts, diagrams, drawings.Use correct unitsUse totals/averages5. Record/Organize Data

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

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

  • 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?

  • The American Woodcock is found in the eastern half of North America It is a popular game bird particularly in the northern eastern states, the great lake states, and in Louisiana.The American woodcock (Scolopax minor) is a shorebird that has adapted to upland habitats. They prefer young, dense successional forests such as aspen stands in their breeding range.Annual survival estimates from banding and recovery data is outdated because most of the woodcock banding efforts ended in the 1980s, a long term spring woodcock banding program continues in Michigan.

    Although banding data is the least biased, it requires a large sample to estimate precise survival estimates. Large samples are difficult to obtain.

    Krementz et al. (2003) used these data to estimate annual survival rates and recovery rates of woodcock from 1978 to 1998. They found survival to be age-specific and that juveniles had a low survival of 26%.
