Raw materials that make up living organisms are constantly recycled between the living and non-living parts of our biosphere. This recycling process is called a natural cycle. Carbon, nitrogen, oxygen, and water are four important cycles.
Your objectives in these learning packets:
Read about and view models of the water, nitrogen, carbon and oxygen cycles.
Do a focused study of one of the cycles.
Complete a final project, a summary of what you have learned.
