1. Graphing
AIM: to show the relationship between dependent and independent variables

2. What are the Characteristics of a Good Graph?
Think, Pair, Share!
1. Title
2. Labeled Axis
3. Proper scaling
4. Using the whole graph
5. Including units!

3. Parts of a Graph Label the X and Y axis, include units
Title – X verses Y is the best title
Label the X and Y axis, include units
Include a consistent scale for each axis

4. Acceptable scales: 0, .1, .2, .3, .4, .5, .6, .7, .8, .9, ,1,2,3,4,5,6,7,8,9,10… 0, 2, 4, 6, 8, 10, 12, 14 … 0, 5, 10, 15, 20, 25, 30, 35…

5. Variables
X axis is always your Independent Variable
Y axis is always your Dependent Variable
If we wanted to test the affects of light on plant growth what would be the independent variable?

6. Plot points carefully and accurately.
Be sure to connect the points with a line.
Label lines and/or provide a key

7. Bar Graphs
Used to compare things

8. Line Graph shows the relationship between two variables
Dependent Variable
Independent Variable

9. What % of the energy is used by fossil fuels?
Circle or Pie Graphs
shows parts of a whole quantity
What % of the energy is used by fossil fuels?
