Using data from Aspen FACE (free air carbon dioxide enrichment), students investigate the effect of carbon dioxide and tropospheric ozone on plant growth. The open-ended inquiry requires students to analyze authentic data sets in order to justify their conclusions. Web sites, tips for modifications for lower-ability learners, guided research questions, and assessment rubrics are included in the article. Students will experience success with the guided inquiry approach to an open-ended problem. Utilizing the numerous teaching resources included, you will be able to implement this inquiry into your classroom with little outside preparation.

The author describes a terrific lesson plan sequence for a student-centered exploration of the interconnections between carbon dioxide, Global Climate Change, tropospheric ozone and plant growth. An initial formative assessment essay example is provided that is used to uncover student misconceptions. A sample guided question set helps students conduct independent background research and pose hypotheses. Students then use real-time data from the current Aspen FACE (Free-Air Carbon Dioxide Enrichment) field research project to analyze data sets and reach conclusions about their hypotheses. This student investigation of a current field research project will give students practice with applying the scientific method and can help students learn how to think like ecologists.
