Winogradsky ColumnCompiled by Sarah Bordenstein, Marine Biological Laboratory
The Winogradsky Column is an excellent activity, specifically for grades 5 - 12, to demonstrate the growth of microorganisms. As a result of this activity, students will:
- learn about the metabolic diversity of prokaryotes, applying terms such as phototroph, chemotroph, autotroph, andheterotroph.
- observe the cycling of mineral elements in natural environments, particularly sulfur.
- discover how microbes occupy a highly specific niche depending on environmental tolerance and energy requirements.
