Variables
The only two things that change in an experiment.
dependent and independent variables
An educated guess
hypothesis

x-axis

taste
The variable that is controlled in an investigation.
independent variable
The reason for doing an experiment.
problem/purpose
The axis for the dependent variable.
y-axis
The time it took a plant to grow with different amounts of fertilizer.
line graph
The basic unit of measurement in the metric system for length.
meter
The variable that is represented on the y- (vertical) axis.
dependent variable

conclusion
These graphs are typically shown with percentages, but how are the percentages calculated
