The fifth graders have been making ecocolumns in groups of two. An ecoclumn is something that has an aquarium on the bottom and a terrarium on top. In a aquarium every group got two snails. In my ecocolumn group, after a while one snail died so than we only had one snail. When one of my partners and my snail died then some of the elodea which is a plant inside the aquarium started d to die two. When both snails died then most of the elodea was mostly dead. Since the elodea needs CO2 and they get it from the snails and since the snails need CO which from the plants, then when one thing dies the other will also die. Latter on we got fish and that could help since they also produce CO for the plants just like the snails.
A terrarium is the land part of the ecocolumn which is on top. My partner and I are growing grass and everyone has at least has one animal which is a cricket. My partner and I have a cricket, two slugs, one potato bug, one ladybug, worms and something else which looks like eggs. The soil and grass giver them shelter and the help the terrarium grow.
Biotic things and abiotic things rely on each other. For example, in the aquarium the gravel is where some sea creatures can sleep. The water is a home to the sea creatures. In the water plants can grow and water is suppose to help plants grow. If there is no water then there will be no sea creatures, all the plants will die. Biotic and abiotic things rely on each other.

Hi, Binyamin,
ReplyDeleteHi, this is Daboh. Wow, that's really cool! I really like the picture of the ecocolumn. And you also said that your partner died along with the snail.... I hope not! I was wondering how you actually made the ecocolumns. Have you guys done owl pellets? There little balls of fur, and bones tat owls threw up. I know its gross, but its actually really fun because you get to dissect it and form the bones into an animal's skeleton.
