Decomposers in Action

For the past month my Garbology 101 class has been engaged in a scientific experiment to see how composting differs depending on 3 different conditions. It began when we took organic waste and broke up into 3 different glass jars with air holes drilled into each lid. In the first jar, we added nothing. In the second jar we added soil. And in the third jar we added water. Then the children had to write down their hypothesis for what they thought would happen in each jar. Over the last few weeks they were asked to make note of their observations and finally yesterday we concluded the experiment. It was jar #2 that resulted in the best conditions for composting, although in all three of them the materials broke down. But the dirt that is in the best condition for use as soil for planting is hands down, jar #2.
