Module 1 - Ecosystems
What is an ecosystem? First, students learn about ponds within the water cycle. Then they learn the components of an ecosystem by building a miniature freshwater ecosystem within a 1-liter glass jar. The module emphasizes both the abiotic factors (soil, rocks, water, air, and sunlight) and biotic factors (microorganisms, plants, animals) that make up ecosystems. In time students will learn how these components are intricately linked and can be influenced by human activities.
