Tube of Rot

As part of my ongoing Masters in Education, K-8 Science Instruction program, I am now taking a course on ecology. As part of the course I need to study decomposition. This "Tube of Rot" will be with me for weeks. Inside these cut apart pop bottles are pieces of tomato, banana, lettuce, spinach, potato, oatmeal, pumpkin (from the jack-o-lantern featured previously), soil, and a starter mixture of bacteria. Yum! This may make a nice centerpiece around Thanksgiving (just kidding honey!).
