In this lab the students built a model landfill from half a 2-liter soda bottle. The soda bottle was partially filled with soil and various organic and inorganic "waste" was buried in the soil. Examples included bread, an orange peel, piece of aluminum foil, a plastic toy soldier, etc. The mass and size and general appearance was recorded in a data table for each piece of sample waste before placing them into the model landfill and hypotheses were generated for each piece in regards to what would become of it in the ensuing weeks. The model landfill was then covered in plastic wrap and monitored over the next several weeks. Here in the pics, the students are opening up their landfills and examining what happened to each of their sample pieces of waste and comparing the results to their hypotheses and explaining the results. They are also comparing how their model landfill is similar and different to the types of landfills discuessed in Ch. 16 of their text.
