Scientific Method CH1

  1. True of False:

    Scientists often use their prior knowledge to predict an experiment's outcome.
    True
  2. True of False

    Most scientists prefer that their discoveries remain a secret.
    False
  3. True of False

    There is just one way to approach a scientific problem.
    False
  4. True or False

    Observation is one way to make a scientific discovery.
    True
  5. True or False

    In a well planned experiment, only one part is changed at a time.
    True.
  6. True or False

    You never have to repeat an experiment. It is a waste of time.
    False!
  7. True or False

    Only university graduates can be scientists.
    False!
  8. True or False

    SI units allow accurate communication between scientists.
    True
  9. True or False

    Nothing is learned if the results do not support the hypothesis.
    False!!
  10. What is Science?
    Science is the systematic process that helps people ask questions about the world around them.
  11. What is a scientists?
    A person who works to learn more about the natural world around them.
  12. What is Technology?
    Technology is the application of science to make products or tools that people can use.
  13. There are two different types of scientific research, what are they?
    • Experimental Research
    • and
    • Descriptive research
  14. Scientist use ________________to try to solve problems so that there are specific steps followed.
    The Scientific Method
  15. The first step of the scientific process is to _________________.
    Identify a problem.
  16. What must you eliminate in order for your experiment to mean something to other people?
    Bias
  17. Why would you use a model in research?
    If something happens too slowly, too quickly or is too big or small or dangerous to observe directly.
  18. What are SI units?
    Units of measure that all scientists use in order to better communicate about their research.
  19. Give some examples of SI units.
    mm, cm, m km, ml, l, mg, g, kg, t
  20. List the steps of the scientifc method.
    • Identify a problem
    • make a hypothesis
    • collect the data
    • analyze data
    • make conclusions
    • communicate results
  21. What is a variable that you are going to manipulate...change on purpose...during the experiment?
    The Independent variable
  22. What is the variable that may change as a result of your manipulation of other variables?
    Dependent variables
  23. What is something that does not change at all during the experiment?
    The Constant
  24. What is a sample that is treated like the experimental groups except that the independent variable is not applied to it. Like in an experiment that looks at the effect of two different types of exercises, it is the group that does not exercise at all.
    The Control
  25. What is biotechnology?
    When technology is applied to living organisms.
  26. What is an engineer?
    A person that takes scientific information and makes it useful to solve a problem.
  27. What is a hypothesis?
    A hypothesis is an idea that can be tested...an educated guess based on prior knowledge.
