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 video explains El Niño and its impact on the marine food web. Wind-driven upwelling in the eastern equatorial Pacific normally lifts nutrients to the sunlit surface to fertilize phytoplankton blooms. El Niño disrupts this pattern, causing... (View More) famine across the marine food web. A big El Niño developed in 2015, shown in satellite images of warmer sea surface temperatures and less chlorophyll - the green pigment in phytoplankton. ClimateBits videos are designed for Science On a Sphere (SOS) and also available on YouTube. Links are provided to more information for this topic from the main ClimateBits website (see related & supplemental resources). (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.

This article describes the the effects of salt and heat on water and its movements. The accompanying game requires the manipulation of those two variables to create water currents leading to a treasure chest. A second article briefly describes six...
