This series helps students identify and explain systems such as the water cycle, the energy cycle, the waste cycle and our atmosphere by examining components within those systems. Students can use the concepts of systems to organize seemingly isolated facts and observations into comprehensible explanations of how things work. The 30 shows are divided into four modules: 1. Land and Water; 2. Conservation and Waste; 3. Energy; and 4. Technology and Human Health.
