These two products, a Science On a Sphere video and docent show (script and playlist), explore factors that render Earth habitable and influence Earth's energy budget. The video gives an overview of NASA's Search for Goldilocks Planets; planets that... (View More) are not too hot or too cold for liquid water. (View Less)
This site features information about constructing a LEGO model of the Global Precipitation Measurement (GPM) Mission Core Observatory. Two options for building the GPM model are provided: students can construct a 3D model on the LEGO website or... (View More) build an actual LEGO model of the satellite (information is provided for purchasing individual parts or for purchasing a pre-packaged kit). In addition to learning about the primary components of the GPM satellite, students will also learn facts about the mission, its technology and instrumentation. (View Less)
Fresh water resources- their quantity, location and distribution- are briefly discussed in this two-page article. The article can be used as a "reading to be informed" activity in a stand-alone fashion or can be incorporated into a lesson plan.
Derived from the Science on a Sphere film entitled "Water Falls," this short (2:50) video presents basic information on the percentage, allocation, and distribution of Earth's usable water.
The Global Precipitation Mission (GPM) collects rain, snow and other precipitation data worldwide every three hours. This short (4:17 minute) video introduces learners to the role of GPM and it's partner satellites in gathering precipitation data... (View More) and the role of Goddard's Precipitation Processing System (PPS) in compiling that data into unified global data sets. (View Less)
Designed for Science On a Sphere, this video is narrated by NASA scientist Peter Griffith who explains fast and slow carbon cycling on Earth. A banana is an example of fast, young carbon. A chunk of coal is an example of old, slow carbon. Carbon... (View More) dioxide and vegetation on land seen from space by satellites show the annual cycle: as plants grow during spring and summer they draw carbon dioxide out of the air during photosynthesis. When they die or go dormant during winter, carbon dioxide levels rise in the atmosphere. Burning fast or slow carbon to generate power or heat releases black carbon, also called soot which can be seen from space. (View Less)
Emphasizing the synergies between science and engineering, these video clips highlight the research of professional ocean scientists and engineers in various disciplines. The clips are accompanied by additional relevant content including images,... (View More) data visualizations, graphs, animations, and other information. Content has been organized into more than a dozen thematic areas such as Solving Old Problems with New Technology and Small Scale Observations and Large Scale Ideas. All content has been aligned with science and engineering practices from the Next Generation Science Standards, including "asking questions and solving problems" and "planning and carrying out investigations," providing applicable resources for teachers who want to provide role models of effective practice for their students.

When New England was hit by Tropical Storm Irene in 2011, there was not a satellite monitoring tropical storms that far north; the Tropical Rainfall Measuring Mission (TRMM) was operating in a band between the 35-degree latitudes. The Global... (View More) Precipitation Measurement (GPM) mission will change that. GPM will build upon TRMM's capacity by examining a larger swath of Earth with instruments that are more advanced and more sensitive. This video introduces the GPM satellite, its instruments and their capabilities. (View Less)
This video provides a glimpse into the snowfall research planned as part of the Global Precipitation Measurement (GPM) mission. GPM Deputy Project Scientist, Gail Skofronick-Jackson, reveals the capabilities of the satellite's new sensors, which,... (View More) through increased sensitivity, will help to overcome the challenges associated with measuring snowfall from space. (View Less)
