Today we created an Ecocolumn using 2 liter bottles. Members of our group brought in various materials. The aquatic level(bottom) contains pond water, snails, leech, rodifer, algae, tadpole, and plant life. In the decomposed chamber we placed grass clippings, dried leaves, banana peel, mushroom slices, lettuce,and cedar mulch. We will continue to add to this level as needed. A gum tree seedling, oak tree seedling, grass, and weeds were placed in top level filled with soil consisting of clay, dirt, and pine needles. There is also a spider and cricket at this level.
Speculation questions discussed included:
*How does energy enter the "system"?
*Is the system open or closed?
We will observe the system everyday and pose new questions as they arise.
