Graphing Review

• Title

• X-Axis Label

• Y-Axis Label

• Scales

• Legend

• Tells you what the graph is about

• Includes the dependent and independent variables

• Tells you what the x-axis (horizontal/bottom line) is showing

• Independent Variable

• Matches the different trails in the experiment

This experiment looked at how leaving a piece of chalk in a cup of vinegar over time would change the weight of the chalk. The independent variable is the time, on the x-axis.

• Tells you what the y-axis (vertical line) is talking about

• Dependent variable

• What we measure/collect data on

In the chalk-vinegar experiment, the mass of the chalk was measured. That makes it the dependent variable, on the y-axis.

• Talk about how one variable changes the other

• As the [independent variable] increases, the [dependent variable] ...

As the time increases the mass of chalk decreases.

As time increases, the speed increases.

You can do it!!!
