EcoTower Observation #3 4.8.11

1. One Betta Fish - alive
Two Snails - dead
Six Crickets - dead
Three Worms - buried in soil unseen

2. We think the fish is still alive because it is surviving off the algae and the oxygen from the water. During this observation we noticed that both of the snails died. We think that either the fish ate the snails or the snails died from lack of oxygen that the algae and water provide. The crickets are dead because, we believe, the carbon cycle failed. We were unable to see the worms to observe if they were dead or not.

3. Three bean seeds - two died and one is still alive
One plant - alive
One plant - dead
Algae - alive

4. As we observed the bean seeds, we observed that two of the bean seeds died and one of them stayed alive. We believe that this happened because the soil didn't look to be as moist as it was. The soil wasn't providing nutrients for the plants. One of the plants that Mr. Jennings gave us is still alive and the other plant died during our first observation. As we observed the bottom half of our EcoTower, we noticed the algae in the water was turning brown on the edges. The algae is turning this color because, we think, there isn't enough oxygen in the water.

5. The water is turning more yellow due to the algae and the rocks.

7. Prediction: Since our fish seems to be surviving in yellowish water and algae that is dying. I think that the fish will stay alive. I think in the top part of our EcoTower all the plants will die because the soil is slowly losing nutrients.
