Our focus on science this trimester is all about ecosystems. We're learning about food webs and food pyramids. We've even had the chance to build our own self-sustaining ecocolumns (terrariums and aqauriums). Each group has two ecolocums, one control and one experimental ecolocumn. The control ecocolumn started with 3 fish, 1 snail, 2 crickets, and 2 isopods + different land and water plants. The experimental ecolcolumns had the same plants and non-linving materials, but no animals. Recently we began polluting these ecocolumns (each group is either using acid rain (vinegar), fertilizer, or salt). We are currently testing the pH levels and observing the effects of the pollution on our experimental ecocolumns.
