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.
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.

This article explores some of the finer details of predicting and understanding tides. SciJinks is a joint NASA/NOAA educational website targeting middle school-aged children and their educators. It explores weather and Earth science through... (View More) articles, videos, images, and games. (View Less)
Hurricanes are discussed as one type of tropical cyclone; the article then describes the four stages of cyclone development. The site includes a video of Hurricane Katrina and a link to a related game. SciJinks is a joint NASA/NOAA educational...

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... (View More) relevant NASA satellite missions. The article is targeted to children ages 10-12. (View Less)
This article describes the work being done by scientists to determine the origin of water found in Earth's oceans. A supplemental exploration of the Herschel Space Observatory is included. The article is targeted to children ages 10-12.
This article provides students with an overview of the technologies used to study the health of the Chesapeake Bay, which is at risk for eutrophication from non-point source pollution. The article describes how data from research vessels, buoys, and... (View More) satellites allow scientists to monitor the growth of phytoplankton. Emerging technologies are discussed, and questions to guide student reading are included. This article is found in Rising Tides, a journal created for teachers and students reporting on current oceanography research conducted by NASA, NOAA, and university scientists, featuring articles, classroom activities, readings, teacher/student questions, and imagery for student investigation of marine science.
