Procedure

Making the eco-column
 * 1) Collect 3 2-liter bottles
 * 2) Mark the bottles with cutting lines as directed
 * 3) Cut along the lines with discretion
 * 4) Mark bottles as directed with letters A,B,C,D,E


 * 1) Fill the bottem layer(A) with about a inch of gravel
 * 2) Apply about another 1/2 inch of gravel on top of the sand
 * 3) Fill the layer(A) with about 350ml of water
 * 4) Collect an Elodea Leaf and plant firmly into the Gravel
 * 5) tape layer(B) on top of layer(A)
 * 6) Cut hole between the two layers


 * 1) Assemble layer(C)
 * 2) Add coffee filter into the bottem part of layer(C)
 * 3) Add about 3 inches of soil into the bottem of the layer
 * 4) Add decomposed material into the layer


 * 1) Construct Layer(D)
 * 2) Add coffee filter to bottem of layer
 * 3) Add 3 inches to bottem of layer
 * 4) Add handful of grass seed
 * 5) Add 2-3 turnip seeds

Add layers altogether in this form top to bottem: e,d,c,b,a

To monitor the eco-column, we do many tests like turbidity, DO levels, nitrates, etc. We do these tests about once a week or when we have time in class.

We plan to add water to the eco-column by putting half a cup of water from the sink into the top layer; then it will eventually end up in the aquatic layer.
