Tracking Tree Growth: Create a Scatter Plot and Trend Line

Explore the beauty of nature through numbers with Tracking Tree Growth: Create a Scatter Plot and Trend Line! This exciting, hands-on activity combines math and science as you collect, plot, and analyze data about how trees grow over time. You’ll learn to use scatter plots and trend lines to uncover growth patterns — just like real environmental scientists!

You’ll begin by working with or collecting data pairs that show the age of trees (in years) and their corresponding heights (in meters or feet). Each pair becomes a point on your scatter plot, where the x-axis represents time and the y-axis represents growth. As you plot your points, you’ll start to see how your tree’s growth forms a visible pattern across the graph.

Once your scatter plot is complete, you’ll add a trend line — also called a line of best fit — to show the overall direction of the data. You’ll observe whether the growth is steady, slowing, or increasing more rapidly over time. This visual pattern helps you describe the correlation between age and height and make predictions about future growth.
