While collecting your data, here are some tables we used that might keep you organized.  Keep in mind, the tables should be made for all samples in all plots.  The data is not actual data collected during our experiment.

For the DO test:

Plot 1 DO in Water DO in soil
A 4.5 7.0
B 6.0 7.8
C 5.6 6.2

For counting protozoa on the microscope slide

Plot 1 Protozoa in View 1 Protozoa in View 2 Protozoa in View 3 Protozoa in View 4 Protozoa in View 5 Protozoa Average
A 16 14 8 20 15 14.6
B 20 23 26 19 24 22.4
C 12 15 14 18 14 14.6

For calculating the density of protozoa. (Number of protozoa per gram of soil)

Plot 1 Grams of sifted soil mL of water added to sifted soil Average number of protozoa in views Calculated number of protozoa per gram of soil
A 9.7 50 14.6 56,218
B 9.5 50 22.4 88,067
C 9.2 50 14.6 58,635

 

Here are the graphs we created after collecting all of our data.  This data is from our findings, and so the pattern you find should look at least a little like the graphs here.

 
These two graphs show the negative correlation between protozoa and volume of air entered into the plot before the aeration process and the positive correlation between the protozoa level and the column of air in the plot after the aeration process.

 

 

Graph 3:

 

These graphs compare the means of the number of protozoa before and after the aeration process.
