Week 2


In the second week since we first made the columns, everything seems to be doing well. For one our plants is taking roots because when you look at our plants closely, you can see that the rooting is taking place by all the new white roots. We did not add any water or anything else to it so far and it is still growing. The reason for this growth is because we have have not watered the plant and when the soil is dry the roots must spread out to search for a water source. My partner and I were surprise when there was a moth flying around by our plants, we are not really sure on how it got in there the first place. As for out aqua section things did not looked too good mainly because the fish were dieing off one by one except for one fish. I believe the reason why the fish have been dieing is because the fish has nothing to eat as out in the lake where there are many creatures the fish can pray on. I learned from Josh that when there is no food in the area, the fish will convert to eating each other to get energy. Aside from the fish, our plant is doing well because the fish is still alive producing CO2 and ammonia for the plant. For our decomposition section, the fungus seems to still be alive, but aside from that I did not see much change it in. Another change that I saw among the entire column is moisture developing along the inside walls of the eco column. The reason for this development is because the inside temperature is much warmer then the temperature out side. Another reason for this is because the humidity inside the eco column is very high thanks to the aqua system at the very bottom of the column. I believe that the water from the bottom of the column evaporates and because of the two different temperature water is formed on the wall of the column, I like to think of it as condensation. When the we can actually see the water drop lets it is called precipitation.
