The Process in Real Life

Students are led out to a composting pile and can see, touch, and smell compost in its varying stages. Measurements are taken of pH, heat, acidity, etc. If available, students are taken to see plants growing in compost.

Assessment: In small groups, students are given pictures of the composting cycle on cards. They are to put these cards in order and each student takes one or two cards and explains to the teacher how the composting cycle works. The teacher also asks comprehension questions.
