DESIGNING EXPERIMENT
DESIGNING EXPERIMENT Independent Variable:
Name
Dependent Variable:
Question:
Question based on:
(observations, prior to research)
What else might affect the dependent variable?
How will I manage the effect of these?
(Look to the right)
Options • Set levels at __________ • Equal numbers of ___ & ___ • Use same subject at different times: __________ • Divide equally between control and experimental groups • Observe and measure • Ignore
Choose�type: (check box) Control vs. Experiment Group vs. Group
What is the first control or group? What is the second control or group?
What am I measuring or observing? dependent variable
Units
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?
Describe the real or imagined findings below
When (I.V.)
,
Then (D.V.)
.
science�does�not�stop
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
