Join Chesapeake Bay Foundation educators Maya, Rick, and Norah as they lead you on a journey through the Chesapeake Bay watershed. Investigate how we are all part of a watershed as you twist and turn from the Appalachian Mountains, through the rivers and streams of Piedmont, all the way down to the Chesapeake Bay. Along your journey, you’ll meet the unique critters that call the watershed home. You’ll also explore what you can do in your own neighborhood to protect the environment and become a Backyard Bay Saver! 

NASA eClips Our World:  Where Do We Find Extremophiles?Video Description:  Where do we find extremophiles? We look for environments that push the limits for ordinary living organisms. NASA conducts analog testing in these extreme environments to better understand life on Earth and identify the potential for life in the universe.  Video Length:  3:25. NASA eClipsTM is a suite of online student-centered, standards-based resources that support instruction by increasing STEM literacy in formal and nonformal settings.  These free digital and downloadable resources inform and engage students through NASA-inspired, real-world connections.NASA eClips Our World videos (grades 3-5) help students understand the differences between science (the natural world) and engineering (the designed world).  These video segments supplement elementary learning objectives not only in science, technology, engineering and mathematics, but also in reading, writing, visual and performing arts.

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.

In this activity, students create a model ocean over which "wind" will be blown, and observe the relationship between the wind and the resulting ocean surface currents. The activity reinforces the concept that surface currents in the ocean are mostly caused by wind. A materials list and instructions are provided, and links to a glossary are embedded in the text.
