There are lots of parts of a graph

• Title

• X-Axis Label

• Y-Axis Label

• Scales

• Legend

Title

• Tells you what the graph is about

• Includes the dependent and independent variables

X-Axis Label

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

• Independent Variable

• Matches the different trails in the experiment

X-Axis Label

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.

Y-Axis Label

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

• Dependent variable

• What we measure/collect data on

Y-Axis Label

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

Trends in Graphs

• Talk about how one variable changes the other

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

Trends in Graphs

As the time increases the mass of chalk decreases.

Trends in Graphs

As time increases, the speed increases.

Time to go take the reassessment!

You can do it!!!
