Students demonstrate and explain the decomposition process. They list the methods and ingredients for making compost. Each pair is provided with a Ziploc quart bag. Students are provided with a "Decay Buffet." They place one small piece of each item into their bags. They then add 1/2 cup of soil to their bags and lightly mist the contents with a plant mister. Students create a compost bag journal where they observe their bags and record what they see happening inside.
