Students continue their examination of the existence of life on Earth. In groups, they determine the role of the water cycle and other biogeochemical cycles play in keeping balance on Earth. They participate in experiments to discover how moisture gets in and out of the air. To end the lesson, they compare and contrast the relationships between biotic-biotic, biotic-abiotic, and abiotic-abiotic interrelationships. Full Review »
