Name: Period: Date: Graphing Activity: Part 1 A study conducted on a college campus tracked the radii of birch trees compared to their age. The data is displayed in the table below: age of birch tree (years) average trunk radius (cm) 1 2.2 2 2.6 3 3.0 4 3.7 5 3.8 6 4.3 Use this information to create a line graph with a title, labeled axes, and a best-fit line. Be sure to take up the entire graph (points should not be bunched in a corner).

Graphing Activity: Part 2 Examine the consistency of the masses of a set of pellets. Is it consistent? Record your data in the table below: number of pellets mass (g) Use this information to create a line graph with a title, labeled axes, and a best-fit line. Be sure to take up the entire graph (points should not be bunched in a corner).
Teacher Notes for Graphing Activity X axis explanation The range of x values from lowest to highest is 1 – 6 years. Ideally, our graph’s x axis should contain numbers slightly lower and higher than this range, so let’s make our graph range from 0 – 7.

Unformatted text preview: We want our data to be spread out across the line, so divide the the number of spaces on the x axis (30) by the difference of our chosen range (7 0 = 7). The answer you get is about 4.3, so to keep it simple and even, every 4 spaces on our x axis will be worth 1 year. Y axis explanation The range of y values from lowest to highest is 2.2 4.3 years. Ideally, our graphs y axis should contain numbers slightly lower and higher than this range, so lets make our graph range from 2.0 4.5. We want our data to be spread out across the line, so divide the the number of spaces on the y axis (30) by the difference of our chosen range (4.5 2.0 = 2.5). The answer you get is exactly 12, so to keep it simple and even, every 12 spaces on our x axis will be worth 1 cm. Note that if 12 squares = 1 cm, then 6 squares = 0.5 cm, and 3 squares = 0.25 cm. The graph...
