DAY NINE

November 11, 2013

Narrative:

Our ecosystem is really not doing so well. At this point, all of our leaves are withering. The stems and leaves of each have turned to a transparent, brown color. Our condensation level seems to have increased from last week. Last week, only one stem was starting to brown. This week, all three stems look sickly. Even our newest plant that was starting to grown within the past few weeks isn't looking too great. One of our elodea plants has turned a bright yellow color. We are not entirely sure why this has happened, but it differs from the rest of the elodea. 

Observations:

A weird spot forming on the wall of our bottle.

Here you can see the health of our leaves.

All three stems are beginning to brown. 

Although our elodea seems to be healthy, one plant is more yellow than the others. 

Predictions:

We are hoping to see some changes in our ecosystem next week. However, these changes could be good or bad. We placed a hole in the top bottle of our system in hopes to create a better flow of oxygen. We were losing hope in our ecosystem, so we were ready to test some variables to see what might happen. Look back next week to see what happened to our ecosystem!

This is the hole we made in the top of our bottle.
