Mrs. Daniels' 7th Hour
Group #2
The Bio in a bottle project (BIB) project took about 5 weeks. The team members were Ben Price, Rachel Schaar, Spencer Reay, Madison Werries, and Leanne Hoag. The team project goal was to have a thriving ecosystem in our BIB and to have the right conditions to be able to sustain a snail and a fish. On the first BIB test the air and water temps were a few degrees on the warm side. The water pH was slightly acidic. The dissolved oxygen was very low and the ammonia was good, the water was a bit murky, but on the 1st day the bottle was doing okay. On the second BIB test the water cooled down and the pH got better, the dissolved oxygen however got worse and so did the ammonia levels, the water clarity was at a perfect 10 and that is where it stayed for the rest of all the labs. On the third lab the pH got acidic again, but the dissolved oxygen improved immensely. The ammonia level also dropped. On Lab 4 the water got slightly cooler but the pH, dissolved oxygen, and ammonia were all very good. On the 5th bio bottle test the water got slightly cooler again and the water pH, dissolved oxygen, and ammonia were all excellent.

Project Highlights & Challenges
Discovery of zooplankton
Discovery of insect larvae
Discovery of snail
Adding the Neon Tetra
Discovering that the Neon Tetra was still alive
Easy stabilization of chemical levels


Had high ammonia- removal of dead leaves and twigs fixed it and it quickly stabilized
Snail died- we had a backup snail and so an additional one was not needed
Brought in the fish late- was brought the day after it was needed

What We Learned
Constructing and stabilizing an ecosystem takes time and can be difficult
There are many factors that must be measured before an environment can sustain life
Without certain biotic and abiotic factors, you cannot support an ecosystem
There are many more relationships between organisms than first meets the eye (symbiotic relationships)
An ecosystem is a very delicate and intricate system, and nature is better at forming these food webs than humans in a laboratory are
