Scientific Method
A planned, organized approach to
solving a problem.
One way scientists ‘do’science
Problem
A question that needs an answer
(who, what, when, where, why,
how)
Research
Finding information to help solve
the problem or answer the
question
Hypothesis
An educated guess. A possible
solution to a problem about the
natural world that can be tested.
Experiment
A data gathering procedure used
to test a hypothesis. Contains a
control and ONE variable
Observation
Using one or more of your senses
to notice objects or events.
Conclusion
It supports or does not support the
hypothesis
A result that has been repeatedly
confirmed.
Report
Sharing your findings to replicate
or confirm your conclusion
Repeat
You should repeat the experiment
if your conclusion does not
support your hypothesis.
Control
The part of the experiment that does
not change. Allows comparison for the
experiment.
Used to show that the results of an
experiment are actually a result of the
condition being tested.
Variable
The part of the experiment that is
changed. It is the one factor
being tested in an experiment
Why must we have only
one variable in an
experiment?
If there is more than one variable, we
will not know what caused the results
we observed, thus making our
experiment invalid.
