Today in biology class we complete one of the compulsory experiments in the IB, making mesocosms. A mesocosm is an experimental system that examines the natural environment under controlled conditions. For our experiment we first put a thin layer of charcoal in the bottom of the jar. We then followed that with a thin layer of sand and a thin layer of soil. This provides multiple trophic levels of interacting organisms. After we put the base down we planted seeds and a few cactuses and leaves. You just need to add a small amount of water and then you are done. We even got to name our mesocosms! Mine is called Kevin.
