Title: Bottled Ecology
Background
Purpose: The purpose of this lab is to understand the network of Ecosystem and to corroborate it
by making our bottled ecosystem to function properly.
Hypothesis: If we create and organize our bottled ecosystem properly, then it will provide factors
that are necessary for life because there would be a direct or indirect link between different
organisms in a different environment.
Research: We used most of our data from the internet. We used the internet to find out the
process of making Eco Column.

Materials: two 2- liter bottles
Bottle caps
Scissors
Water (aquatic water that we got from my stream)
Soil (Science classroom’s soil)
Worms (Science classroom’s worm)
Rocks for aquatic life
Eggs of Triops
Food items for decomposition
Other food to feed Triops
Grasses that we plucked from our backyard
Procedures: 1) Use scissors to cut the 2 liter bottles. The bottom section is aquatic life.
2) Put handful of rocks into the aquatic chamber and put aquatic water from the
stream. Put sand and may put moss. Later put 7 aquatic grasses that will help photosynthesis in
aquatic chamber and one small half full of plastic bag of triops eggs that will later grow up to
swim around. With the top of the bottle which was cut, put it upside down into the base bottle.
3) We puncture the bottle cap with the needle. Pour two handfuls of soils and put
them in the decomposition chamber. Put decomposer like worms or spiders in with some food
for them to survive.
4) With another top of the bottle, put it upside down on the other bottle. This
chamber is called terrestrial. Be prepared to have plants like grass (all the way down to the root).
Make sure to add right amount of soils that will cover the root of the grass.
5) Finally, making the eco column is done.

Conclusion
Therefore, as we said if we create our bottled ecosystem properly, then it will provide factors that
are necessary for life because there would be a direct or indirect link between different
organisms in a different environment. We think our hypothesis was right. Eggs we put in the
aquatic chamber have not hatched and so we have to replace them with other fish that could
survive in our eco bottle. We would have to watch our bottled ecology for a year.
