Mitchell had to do this Ecocolum project. This Ecocolum you can design bottle habitats for animals and plants. We had to collect 7 2-liter bottles and cut the the tops and bottoms off. Then he was given a fish and we created in the bottom chamber a place for the fish to live. The next chamber was to create food and oxygen for the fish with a plant. The plants roots were in the water for the fish to eat. Then above the plant, we placed a banana peel to decompose and hatch fruit flies. The final chamber was a venus-fly trap plant to eat the fruit flies. This creating a whole ecosystem of life. This was a lot of fun and a great project to do at home with him.
