To better understand the processes that change it we can visualize Earth as four interacting systems—the geosphere, biosphere, hydrosphere, and atmosphere. Humans are part of the biosphere, but have the ability to impact all of Earth’s spheres in both positive and negative ways.
Students will investigate Earth systems by making observations in nature and identifying systems in the natural world. Ultimately, the students will understand how the four spheres/systems on Earth (biosphere, hydrosphere, geosphere, and atmosphere) are interconnected.
Build A Bottle Ecosystem! Grades: K - 6 Time: 1 hour to assemble. Lesson summary: Discover how ecosystems work. What’s the big idea? • What’s an ecosystem? • What role do plants and water play in ecosystems? Learn how ecosystems work by making a bottle ecosystem. Teacher background: Outcomes or purpose:
These parts, which you have learned as spheres, interact in very dynamic ways to produce everyday life as well as natural disasters. In this project, you will demonstrate your understanding of each sphere, how it interacts with other spheres, and how Earth represents a system.
1. What is a system? 2. What is the Earth's systems? 3. What are the Earth's spheres and how do the spheres interact? 4. What can humans do to diminish their impact on the hydrosphere, atmosphere, geosphere, and the biosphere?
Students will discuss picture examples of the five Spheres, collect data to generate their own bar graph, and experience interactions between the five Spheres on Earth. Students will be able to identify and differentiate impacts and interactions between the Biosphere, Hydrosphere, Geosphere, Cryosphere, and Atmosphere.
These NASA lessons support Next Generation Science Standards (NGSS) and three dimensional learning of the Earth System. These include activities where students interact with NASA maps, graphs, and datasets from the atmosphere, biosphere, cryosphere, geosphere, hydrosphere and the earth system.
