Experimenting With Plant Growth

by Kristin McCully and Jack Horner

Students, as a class, develop, conduct, and analyze an experiment to determine what affects the growth of an “ecosystem in a jar.” “Ecosystems” include soil, water, plant seeds, and other items decided by the class in glass jars. Discussion should focus on experimental design and analysis, but instructor can incorporate ecosystem ecology, biodiversity, food chains and webs, photosynthesis and respiration, and other concepts of ecology and biology.
