Teachers and students can dive deeper into our world’s oceans with this site from the National Oceanic and Atmospheric Administration (NOAA). “Ocean Explorer” enables teachers and students to follow along with current government expeditions, learn about oceanographic exploration technologies, and become acquainted with many of the awe-inspiring life forms living beneath the waves. Visitors can explore the ocean floor, learn about creatures that make their home in the sea, and go back in time to understand how technology and oceanic exploration have changed throughout the years. There is also a virtual library of reference materials where students and teachers can further their underwater education. In the site’s “Explorations” section, students and teachers can follow timelines and underwater images that will take them chronologically through many of the great ocean expeditions of past and present. The “Gallery” contains a wealth of underwater images and audio files that bring many of the sea’s mysterious inhabitants to life. Also, an online calendar lists upcoming ocean-related events. At a time when 95 percent of the world’s oceans remain unexplored, it is NOAA’s hope that this site will encourage students to want to learn more.
