Students create and tend to an outdoor compost pile. They research about decomposition and composting. They create two activities for their peers to complete.

Students are introduced to the concept of decomposition. They examine decomposition in their school orchard. They write about their findings in a journal.

Students observe properties of items, determine time it takes for organic/inorganic items to decompose, identify differences/similarities between decomposition, identify practical uses in litter/garbage control, & establish reasons...

Students conduct an experiment in which they bury four objects (apple, lettuce, plastic and styrofoam) in the ground and come back to observe them a month later. They consider what biodegrades and how it affects our planet.
