Urban Ecosystems

When people think of ecology, they usually imagine studies out in the country. The next thing they think of is studies involving the relationship of plants and animals to one another. They also imagine studies that show how organisms relate to the physical environment -- air, water, and soil. People and cities usually don't come to mind when ecology is mentioned.

Day 7: Be A Data Display'a!


Bar graphs involved two variables represented on two axes. Data can be visually displayed on a bar graph.

Lesson Overview

Students will create bar graphs to represent the data that that they have collected

1 class period
  • Student Sheets
  • Collected Data
  • Pens/pencils
  1. Using the student sheet, explain to the students the concept of the bar graph and how it is created.
  2. You may wish to walk the students through the creation of the first bar graph. Be sure that the students have ready access to the data that they have collected for land use types as well as one or more of the following: Worms, Percolation, Recording Schoolyard Use.

Closure: This lesson leads right into the next activity which is designed to allow the students to mentally pull the data from the three graphs together to draw conclusions about their schoolyard.
