Learn about the GLOBE Program student investigations that explore the Earth’s hydrosphere - the water component of our planet, including liquid water, ice and vapor. Changing any part of the Earth system, such as the amount or type of vegetation... (View More) in a region or from natural land cover to an impervious one, can affect the rest of the system, and water plays a role in many of these changes. Rain and snow capture aerosols from the air. Acidic water slowly dissolves rocks, placing dissolved solids in water. Dissolved or suspended impurities determine water's chemical composition. Water is a good solvent and participates in many of the chemical reactions that take place in the Earth system. Water provides a habitat for mosquito larvae. GLOBE eTraining provides the opportunity for new and existing GLOBE users to complete science protocol training online and consists of downloadable training modules, interactive digital field and lab experiences, and online assessments for each module. GLOBE (Global Learning and Observation to Benefit the Environment) is a worldwide, hands-on, K-12 school-based science education program. (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.
A Hovmuller plot is a diagram that visibly displays data patterns from a selected latitude or longitude over a time period. Through a storyline and several samples, students are introduced to a Hovmuller plot of temperature data along a longitude in... (View More) the eastern United States. Students then create salinity and precipitation plots using data from the MY NASA DATA Live Access Server. (View Less)
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.
This brief (1:58) video provides an explanation of El Niño and its impact on the marine food web. Satellite images of a large El Niño in 2015 show the impact on both water temperature and phytoplankton blooms. ClimateBits videos are designed for...

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.
