Topex/Poseidon (continued)
The "image library" includes graphics of dynamic ocean topography, sea surface variability,significant wave height, wind speed, and precipita ble water vapor.

The Educational Resources section contains an online tutorial which presents ideas on how to incorporate the TOPEX/Poseidon data on the Internet into the classroom. This tutorial can be used effectively as a stand alone tutorial for secondary student s in a networked computer lab. Many sections of the tutorial contain images which can be used by teachers as presentation materials to explain oceanographic science processes and concepts.

El Niño Theme Page

This web site contains a wealth of information about El Niño. The material at this web s ite is appropriate for students in grades 10 -12. Graphic images and animations facilitate learning about El Niño. Extensive information about the impacts of El Niño and benefits of El Niño prediction are presented with many web links to re cent graphic images on the Internet. Teachers and students can access the latest El Niño forecasts and measurements which include global sea surface temperature, equatorial Pacific sea surface temperature, and tropical Pacific buoy data. These datasets can be used in the classroom for graphing and data analysis activities.

Ocean Planet
http://www.seawifs.gsfc.nasa.gov/ocean_planet.html
Ocean Planet is an online exhibition from the Smithsonian Institution. This online exhibit contains extensive information on many different oceanographic topics including ocean science, sea people,"SEA store", marine pollution, threatened habitats, global change, fishing issues, and much more. This exhibit contains many great animations and movies of ocean topography and also many audio sounds of the sea. Ocean Planet has many excellent K-12 lesson plans throughout the exhibit.

A special section of this web site contains marine science and classroom lessons activities from the Smithsonian which adapt several themes of the exhibition for use in the middle and high school classroom. Each lesson plan contains teacher and student objectives, materials, detailed procedures, downloadable student handouts, and links to additional resources on the WWW. These lessons include:
