Earths Systems and the Environment

Help 6th graders see Earth as one connected machine. This guide introduces the four major systems (geosphere, hydrosphere, atmosphere, biosphere), shows how they constantly interact, and explains key ideas like the water cycle, weather vs. climate, ecosystems, and food webs. Students also explore human impacts (pollution, habitat loss, climate change) and practical solutions (conservation, recycling, sustainable living). Includes diagrams, reflection prompts, scenario analyses, and printable worksheets for real-world practice and classroom assessment.
