The purpose of this resource is to measure the salinity of the water at your hydrology site. Students use a hydrometer to measure the specific gravity of the water sample, and use a thermometer to measure the temperature. With these two values, students will use tables to determine the salinity. Full description.

Online in 2009, the Aquarius instrument will measure sea surface salinity. Site provides background information about salinity, salinity lesson plans, and salinity data and tools. Activities include relating salt to density, conductivity, buoyancy, and understanding the effect of the water cycle on salinity. View figures of sea surface salinity and temperature as they change from month to month and ... Full description.

This activity requires construction of a simple salinity tester. Students will create their own calibration scale during this experiment, and look at the change in salinity that would arise if freshwater was suddenly dumped into the ocean. Materials needed for this investigation include a DC mill ampere meter, 2 D-cell batteries and holder, bronze sheeting, #18 solid wire, salt, deionized water, and ... Full description.

The educational resources and activities on this Web site teach fundamental concepts about salinity variations and the role these changes play in controlling global ocean circulation and Earth?s climate. The modules augment existing El Nino/La Nina materials with salinity-based content, provide on-line interactive tools demonstrating environmental change through data sets and in situ time-series analysis, ...

This resource uses text, images, maps and a laboratory exercise to explain how differences in the temperature and salinity of ocean water cause the formation of deep-ocean currents. It is part of the Jet Propulsion Laboratory's "Ocean Surface Topography from Space" website. This material is also available on the "Visit to An Ocean Planet" CD-ROM. Full description.

The video is a procedural guide to sampling salinity measurements in water bodies in the field. It provides a step-by-step explanation of field procedures and features students conducting the investigation and asking questions about what changes in salinity could indicate in rivers, lakes, and estuaries. The resource includes a video, transcript, and is supported by the Salinity Protocol in the GLOBE ... Full description.

This resource introduces students to the idea of saline water. Topics include how saline water is defined and how dissolved salt concentrations are expressed (parts per million). Parameters for the various ranges of salinity (fresh to highly saline, or seawater) are also presented, and there is a brief discussion of water quality considerations regarding saline water. Links to additional information ... Full description.

In this activity students work as a team to determine the effect salt has on plant germination. They then use their lab data to create a report on how the increasing salt concentrations affected the germination of the seeds and at what salt concentration no seeds will germinate. Students will discover that salt buildup is an existing or potential hazard on almost all of the 42 million acres of irrigated ... Full description.
