Create a Mini Ecosystem

Worksheet Description

The worksheet provides students with instructions on how to craft a small, self-contained ecosystem within a glass jar. Through this project, learners can observe firsthand how plants, soil, and water interact with each other in a closed environment, giving them a tangible example of ecological dynamics. The worksheet lists the materials required and offers a detailed step-by-step guide, ensuring that students can follow along and successfully create their mini ecosystem.

To create this mini ecosystem, one begins by placing a layer of small pebbles or gravel at the bottom of a clear glass jar. This is followed by adding activated charcoal on top, which aids in absorbing impurities. A deep layer of potting soil is then added, where plants, moss, or small ferns are planted. The soil is moistened carefully, ensuring not to overwater. The jar is then sealed and placed in a spot with indirect sunlight, and over time, the students can observe the growth of the plants and the water cycle inside the closed environment.

This worksheet aims to cultivate an understanding of ecological interactions within students. By constructing a mini ecosystem, learners grasp the importance of each component and their interdependencies. They also gain insight into the water cycle and the role of sunlight in plant growth. By observing and maintaining their ecosystem over time, students are encouraged to appreciate the delicate balance in nature and the significance of ecological preservation.
