This activity demonstrates optical properties of water: that different constituents in water affect the transmission, absorption, and scattering of different colors in the visible light spectrum. Inexpensive, off-the-shelf components are used to... (View More) build a light sensor and source, creating a simple spectrophotometer that can measure light absorption. In the second part of this activity, principles of ocean color remote sensing are applied to measure reflectance. Using components that are clearly visible allows students to configure them in different ways. Playing with the instrument design gives students a practical understanding of spectrophotometers, in-water optics, and remote sensing. As an extension of this concept, students are encouraged to think about how ocean color is used to estimate the concentration of chlorophyll to infer phytoplankton abundance, colored dissolved organic matter, and suspended sediments.

In this video clip, viewers learn about the cryosphere - all of Earth's frozen structures including sea ice, ice caps, and permafrost. Understanding changes in the cryosphere provides scientists with valuable information about the past, present, and... (View More) future of the planet. ICESat-2 is a satellite designed to help scientists learn more about Earth's ice and the role ice plays in climate. NASA eClips™ are short, relevant educational video segments. These videos inspire and engage students, helping them see real world connections. The Real World series of NASA eClips connects classroom mathematics to 21st century careers and innovations and are designed for students to develop an appreciation for mathematics through real-world problem-solving.

In this video clip, viewers learn how NASA's SAGE III instrument is providing valuable information to help understand how our global Earth system is changing. Find out the difference between good ozone and bad ozone. Learn about the health problems... (View More) that a small percent of our atmosphere, or only a few parts per billion, can create. NASA eClips™ are short, relevant educational video segments. These videos inspire and engage students, helping them see real world connections. The Real World series of NASA eClips™ connects classroom mathematics to 21st century careers and innovations and are designed for students to develop an appreciation for mathematics through real-world problem-solving.

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.
Images from NASA satellites showing atmospheric phenomena such as cyclones, hurricanes, high/low pressures, clouds and the jet stream are featured in this 10-minute planetarium show.
In a one minute time lapse video, viewers are shown the assembly sequence of the Global Precipitation Measurement satellite from its 2011 beginning at Goddard Space Flight Center in Maryland to its 2014 launch at Tanegashima Space Center in Japan.
This short (11:29 minutes) video features NASA scientists answering a set of student-designed questions related to NASA’s Global Precipitation Measurement satellite mission. The set of twelve questions were generated after students viewed... (View More) animations of GPM data; the questions centered on satellite operations, satellite data, and precipitation patterns and impacts. (View Less)
The Global Precipitation Measurement mission provides a global perspective on rain and snow, along with the storms, impacts, patterns, hazards, and changes associated with those precipitation events. Several such events, which occurred during a... (View More) one-week period in August 2014, have been compiled into this short video (5:42 minutes) which features narration by NASA scientists.

This Science On a Sphere video and docent show (script and playlist), explores 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 are not too... (View More) hot or too cold for liquid water. (View Less)
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 dioxide and vegetation on land seen... (View More) 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. ClimateBits videos are designed for Science On a Sphere (SOS) and also available on YouTube.
