Graphing Practice
Today’s Learning Goal:
A good graph has the following:
 A Title describing what the graph is telling you.
 Correctly identified Independent and Dependent variables.
 Labeled axes with an appropriate scale.
 If it is a multiple line graph a Key should be provided.
Graphing Guided Practice Problem # 1
The thickness of the annual rings indicates what type of environmental situation was occurring at
the time of its development. A thin ring, usually indicates a rough period of development. Lack of
water, forest fires, or a major insect infestation. On the other hand, a thick ring indicates just the
opposite.
Age of the tree in years
Average thickness of the annual rings in cm.

Graphing Guided Practice Problem # 2
Building off the previous example:
The thickness of the annual rings indicates what type of environmental situation was occurring at
the time of its development. A thin ring, usually indicates a rough period of development. Lack of
water, forest fires, or a major insect infestation. On the other hand, a thick ring indicates just the
opposite.
