Kristine Cho's Ecocolumn

In our Environmental Science class, we were given the assignment to build a 3 leveled eco-column. In the top tier would be the "Terrestrial Level"(soil/planter mix), the second tier would be the "Decomposition Level"(leaves, grass, planter mix, pill bug), and the last tier would be the "Aquatic Level"(fish, Snails, plants)

Testing
This week we were given the assignment to assemble our eco-column and to start testing. We tested the water and soil in the tiers to find components of an ecosystem such as Temperature, pH, Dissolved Oxygen, Nitrates, and Phosphates.
