   1. List and describe the six steps of the scientific method in order:
   State the problem – Identify what will be researched or studied
   Conduct research – Find out what information has already been studied
   Create a hypothesis – Make a guess as to what the answer to the problem will be
   Conduct an experiment – test your hypothesis in a controlled way
   Analyze your data – Look at what observations were made and what information came out of the
   experiment. Make charts or graphs to help.
   Create a conclusion – Summarize what happened in the experiment and discuss your findings.

    2. What is the difference between an independent and a dependent variable?
    An independent variable is changed by the experimenter and the dependent variable changes as a
result of it. There should only be one independent variable in an experiment.

   3. What is the control of an experiment?
   The control of an experiment is the base line that is used to compare the results to. If a variable is
   tested, the control would be the one where the variable is not changed from its original state.

   4. What are constants?
   Constants are parts of an experiment that do not change. There are many of these in an experiment,
   and only one independent variable.

   5. What are important things to include in a conclusion?
   Was the hypothesis right or wrong? What happened in the experiment? What was learned? Were
   there any sources for human error? What would you do differently if you were to complete the
   experiment again?

   6. What are the three important parts of a hypothesis?
   If… (the setup)
   Then …. (what you believe will happen)
   Because… (why you think that will happen)

   7. What are examples of resources that can be used in completing research?
   People - experts, teachers, peers.
   Books, magazines, newspapers, internet.
   TV, movies, etc.

   8. What should be done after a hypothesis is created but before an experiment is conducted?
   Materials should be gathered and a procedure listed in detail.
