Scientific Method
Observation Question Hypothesis Variables Independent Variable Dependent Variable Controlled Variable Groups Data Conclusion
Independent Variable
What you are changing during your experiment? I CHOOSE I CONTROl goes on x-axis
Dependent Variable
The thing you are measuring during the experiment that your independent one changes goes on the y-axis
Constants
Things you keep the same during your experiment
Control
The group that receives no treatment during the experiment that you compare to
Volume
Liter (L) Use a graduated cylinder
Length
Meter (m) Use a meter stick/ruler
