Building a Mesocosm

IB1 students were asked to construct a mesocosm, which is a closed ecosystem that allows for variables to be controlled. Ours students used five bottles, 1 aquatic plant, some distilled water, coal, soil, cat poop (this was left in one of our student’s sunflower pot, which happened to be their individual investigation, so we decided to make use of it in our mesocosm), 3 earth worms, cress seeds, and rocks and some compost. The mesocosm is thriving near a window in our room and has been growing for several months now. We look forward to examining it next academic year.

Below are some photos. Enjoy.
