Grade 5

Global Water Distribution

Extension 1 Instructional Focus


The Gravity Recovery and Climate Experiment (GRACE) satellites study gravity variations on land masses to provide the most detailed picture available of vital fresh water reserves hidden beneath Earth’s surface.  The International Space Station’s Environmental Control and Life Support System (ECLSS), a water purification component developed for astronauts working in space, is now used to supply clean drinking water to remote and impoverished communities across the globe.

Extension 2 Instructional Focus


Students write a narrative with the aid of supporting materials from NASA and the Science Channel, in alignment with the Common Core State Standards.  Narrative prompt:


Imagine that you are the commander on board the International Space Station.  Suddenly, Mission Control notifies you that you must evacuate immediately, due to the danger of a major collision with a piece of space junk.  How do you feel? What do you do next?  What happens?  What do you learn from this experience? Include details from the NASA article entitled, “What is Orbital Debris?” in your narrative.
