the scientific method?
What is important about
a hypothesis?
Problem/Question
Hypothesis
Experiment
Scientists want to know
why things happen
Scientists develop an “If,
then” statement.
Scientists must be able
to TEST their hypothesis
Scientists test their
hypothesis
Data Analysis
Scientists look at their
data
Conclusion
Was their hypothesis
supported or refuted?
Why or why not?
Report Findings
Scientists want others to
know and they can also
test the findings
