Eco-Column Project
By: Katelyn Currie
1. My name is Katelyn Currie.
2. The experiment name is Eco-column
3.The purpose was to see 1) if we could keep everything alive and working the whole time and 2) so that we could witness how a fish can stay alive without being fed, just by living off of the nutrients in the water.
Title Page and Details:
Hypothesis Task:

1. Atmospheric Chamber, If we add an atmospheric chamber to our eco-column, then that part will allow more air flow through the terrestrial chamber because it will put more space between the grass and the top opening, and it will also allow condensation to appear.

2. Terrestrial chamber, If we successfully grow grass in our terrestrial chamber, then flies will appear in the chamber because it will be warmer in the chamber with grass and the atmospheric chamber.
3. Decomposition Chamber, If we only use leaves, then the fish in the aquatic chamber won't get enough nutrients because the leaves will decompose before the experiment is over.
4. Aquatic Chamber, IF we only put one elodea piece in the chamber, then the fish won't have enough oxygen because the elodea can only produce so much oxygen.
Details of Written Instructions:
2. Instructions Terrestrial Chamber:
1. Remove the labels from two two liter bottles.
2. Cut off the top of bottle one, (two to three centimeters below the shoulder so that cylinder has straight sides).
3. Cut bottom off of bottle two (one to two centimeters above hip, so that cylinder has a straight end).

4. Poke many small holes in the cap.
5. Inert "b" and stack onto base"d". Add top "a" with a piece of tape for a hinge to the bottom column.
6. Poke air holes in column "b".
8. Mass and add stream/pond or rain water to materials.
7. Mass all materials separately before adding.
Eco Column Set Up Guide
Decomposition chamber set up:
1. Remove labels from two
1. Remove the labels from both two liter bottles.
decomposition layer set up:
2. cut the top off bottle #1 (2-3 cm below the shoulder so that cylinder has straight sides).
8. Mass and add stream/pond or rain water to your compost.
7. Mass all compost material separately before adding.
6. Poke air holes in bottle "B".
5. Invert "B" and stack into base "D". Add top "A" with a piece of tape for a hinge to the bottle column.
4. Poke many small holes in the cap "c".
3. cut bottom off bottle #2 (1-2 cm above the hip, so cylinder has a straight end).
4 Laws of Ecology
4. Nothing comes from nothing, which means Exploitation of nature will inevitably involve the conversion of resources from useful to useless forms. In nature, both sides of the equation must balance, for every gain there is a cost, and all debts are eventually paid.
2. Everything must go somewhere, which means no matter what you do, and no matter what you use, it has to go somewhere. For example, when you burn wood, it doesn't disappear, it turns into smoke which rises into the air, and ash, which falls back down to the earth.
1. Everything is connected to everything else, which means humans and other species are connected/dependent on a number of other species.
3. Nature knows best, which means Like it says, nature knows best. As much as you think it might help a place by repainting it, you are submitting the fumes into the air and into your lungs. Why not put siding on it?
Food Web
Roles of factors:
1. The fish eats the elodea and the nutrients in the aquatic chamber
4. The flies eat the grass in the terrestrial chamber and the fruit and leaves in the decomposition chamber.
3. The pill bugs and the worms also help to break down the fruit and leaves in the decomposition chamber.
2. The mold helps to break down the fruit and leaves in the decomposition chamber.
Aquatic Chamber:
1. The water went from crystal clear to a browny-orange color.
2. When we put snails into our chamber, the elodea leaves were slowly getting smaller.
3. As the water started to change, our first fish died.
Decomposition Chamber:
1. When we left the compost alone for a while, it got moldy.
2. When the compost got moldy, it started to decompose faster.
3. When it decomposed faster, there was more dirty compost water that dripped into the aquatic chamber.
Terrestrial Chamber:
1. We over watered our grass and the seeds drowned.
2. When we put more seeds in, the grass started to grow again.
3. When the grass got moldy, flies showed up.
Changes in the different chambers:
My eco-column was something in-between, this made it easier to change something that went bad, like a dead fish or dead grass.
There were little flies in the terrestrial and decomposition chambers. There was white mold in the decomposition chamber. The mold showed up because we had rotting food in our chamber, and I have no idea why the flies showed up.
I believe that my eco-column was stable, and I also think that some others were better. I think this because we had two fish die, but once we got the guppy, everything worked just fine.
My ecosystem had fish die, like everyone else. Mine was different because at the end we had beautiful green grass while most people had dead, brown, moldy grass.
