Most middle level students are too young to recognize on their own the complex relationships among the natural cycles. They seldom connect one cycle with another nor do they see the relevance of the cycles to human events and natural phenomena so it is the job of the teacher to jump start students “discovery” of the interconnectedness, or example, of the lithosphere, hydrosphere, atmosphere, and biosphere and the cycles of matter and energy.
