Planting the Terrariums

To introduce the concept of living and nonliving components of an ecosystem, students consider a terrarium. They examine and plant seeds and observe germination. They examine the nonliving components of the ecosystem that growing plants need for survival. They begin a log of terrarium plant growth, and learn that not all seeds germinate and survive. Students follow the life cycle of a bean plant from germination, observing root formation and measuring plant growth. Graphing plant growth and germination rate allows students to quantify their observations.
