Learn about the importance of public policy action on natural resource and conservation issues. This episode highlights some key pieces of conservation legislation. The American system of land and wildlife management is one built on, and for, public involvement. Learn about how these decisions are made and, most importantly, how to get involved.

Video Description:  Our Earth is a dynamic system with diverse subsystems that interact in complex ways.What are those subsystems and how do they interact?How are these subsystems and the global Earth system changing?What causes these changes?How does NASA monitor these changes?How can Earth system science provide societal benefit?Jessica Taylor, an atmospheric scientist at NASA Langley Research Center, and Dr. Steven Pawson, an Earth scientist from NASA Goddard Space Flight Center, help answer these questions and demonstrate how mathematical modeling helps scientists in their predictions of climate, weather, and natural hazards.  Video Length:  5:02.NASA eClips Real World segments (grades 6-8) connect classroom mathematics to 21st Century careers and innovations.  They are designed for students to develop an appreciation for mathematics through real-world problem solving.

Video Description:  Balancing Earth's incoming and outgoing energy is like balancing an equation. When both are equal, Earth's energy is in balance. Learn more about how changes in this balance may impact Earth.  Video Length:  2:56.NASA eClipsTM is a suite of online student-centered, standards-based resources that support instruction by increasing STEM literacy in formal and nonformal settings.  These free digital and downloadable resources inform and engage students through NASA-inspired, real-world connections.NASA eClips Real World segments (grades 6-8) connect classroom mathematics to 21st Century careers and innovations.  They are designed for students to develop an appreciation for mathematics through real-world problem solving.

Video Description:  Earth's energy balance is very delicate. Small changes may have a big impact. How might changes in Earth's land and atmosphere impact this delicate balance? How might this knowledge be used to help us take better care of Earth?  Video Length:  2:31.NASA eClipsTM is a suite of online student-centered, standards-based resources that support instruction by increasing STEM literacy in formal and nonformal settings.  These free digital and downloadable resources inform and engage students through NASA-inspired, real-world connections.NASA eClips Real World segments (grades 6-8) connect classroom mathematics to 21st Century careers and innovations.  They are designed for students to develop an appreciation for mathematics through real-world problem solving.
