When will I measure?
independent
variable
How will my data look if it supports my hypothesis?
How will my data look if it does not support my hypothesis?
independent�variable
Part of the experiment changed
by the experimenter
Dependent�Variable
Part of the experiment that changes
because of the I.V. - is measured or
observed to get data
constant
Parts of the experiment that remain
the same to prevent affecting the
experiment’s outcome
Control
Level of the I.V. that you compare
back to- unchanged or in the
natural state
What could go wrong in this experiment?
RESULTS
How can I prevent or deal with these problems?

When (I.V.)
,
Then (D.V.)

What is my next step?
options
• Write a clear precedure that other
people can follow step by step
• Create an organized data table of
your results
• Display the data in an organized
chart or graph (if possible)
NEW questions to investigate
