Week 8

(Field Trip on Monday, week 7)




Plant on top: 3 leaves have died on the very top. The leaves left brown residue on the lining of the bottle. This residue has slipped down the bottle and ran through the tape (from condensation). The bottle has some brown leakage/fluid on the outside. There are still 3 healthy leaves, and the plant looks overall alive and thriving. The 2 shorter sprouts are still growing white spores/mold from the stems.
Soil: looks like it has decreased/meshed together. The soil is very wet and appears packed down. There is a lot of condensation on top. The fly is still hanging out in the top of the bottle!
Water: The water level is 2 cm. below the bottle cap. The water quality is still good. It appears clear, with few "floatages." The string between the bottle cap and the water level is dark brown. The string in the water is falling apart and disintegrating. 
Elodea: Grown so much! It appears to have almost doubled, or even tripled in overall length. 
Roots: The root from the top of the soil has wrapped around the elodea twice, in two different spots. It is touching the gravel at the very bottom of the bottle. 
Snail: 2 big snails at the bottom. One of the big snails is laying face up and appears dead. There are 3 baby snails on the elodea. They are moving slowly. 
Daphnea: still cannot see

Predictions: I predict that the eldoea will keep growing and growing. This seems to be the healthiest life in the entire bottle. I think the tallest plant on the top, with the dying leaves, will start the decay. The 2 smaller sprouts should keep growing and getting taller. The snails might start to die because I can hardly see any algae or food for them.
