Experiment

In our experiment we had the three bins and filled it with three cups of dirt.  By having the bins have equal amounts of soil it makes the soil balanced.  Once we completed putting in the dirt we put in 8 worms in each of the bins.  In the three put three different things.  In the first bin we put in regular dirt, because even if mulch is a good way to produce, we wanted to see how it would work with only the fertilization in the dirt itself. In the second bin we put in Coffee grinds and tea leaves.  Many people coffee in the morning with the coffee filters included we wanted to see if we could recycle this material.  In the third bin there was kitchen scraps. Everything else that could be made into mulch including peppers, onions, carrots, rice, peels and ends of vegetables, and many more.  We were wondering about everything else that people use. 

After we put everything together, we put the bins in the garage because it is dark and the weather outside has no effect on it.  When we put it in the garage we waited 3 weeks for the materials to decompose.  If we didn’t wait long the materials wouldn’t be able to decay and it wouldn’t give the worms time to eat the waste of the materials.  Every week we would put more things in the bin to be decomposed. 

After the three weeks were over we converted the decomposed soil into the germinator.  We put the four types of seeds in each of the three different soils.  The seeds we put in the soil are radishes, peas, spinach, and cilantro.   In each separator in the germinator we put in three seeds in each separator.   For each plant we had two separators.  We wanted to make sure that there wasn’t a mistake planting process.  If there were bad seeds then the plant wouldn’t grow, but having 6 seeds it would grantee that there wasn’t a mistake. 

            When we observed the plants when it was growing we watered it and had the plants inside by a window, so it would have plenty of sunshine.  We let it grow for two weeks before we compared the difference between the plants.  We measured each plant in centimeters and that is how we got our conclusion.
