2 - COW'S EYE DISSECTION UPDATE
http://www.exploratorium.edu/learning_studio/cow_eye/
The Exploratorium is redesigning the online Cow's Eye Dissection and would like your input.

Have you done a cow's eye dissection before? Have you used our Web resource with your students? If so, please send email to noahw@exploratorium.edu?subject=Cow's Eye Dissection ideas to let us know what we can do to make this resource more usable and valuable.

The new site will likely follow the structure of the original. Each step will be available as a video clip or photos + text. We will make the Cow's Eye primer diagram http://www.exploratorium.edu/learning_studio/cow_eye/primer.html available as an interactive Web resource and create new PDFs of the site for easy downloading and printing.

3 - GLOBAL CLIMATE CHANGE: THE HYDROSPHERE
http://www.exploratorium.edu/climate/hydrosphere/index.html
The oceans, which cover more than 70% of the earth's surface, play a fundamental and complex role in regulating climate. When ocean currents flow over large distances, water of one temperature is carried into zones of another temperature. There are annual shifts in ocean currents and temperatures. These changes in ocean conditions are interconnected with seasonal weather patterns, such as monsoons and droughts. Learn about weather patterns, El Nio/La Nia, and sea surface temperatures.

4 - THE SCIENCE OF HOCKEY
http://www.exploratorium.edu/hockey/
Learn the why and how behind ice hockey. This site takes you inside the game. Find out why ice is slippery, the speed of a goalie's reaction time, and how the temperature of a puck affects its motion. (You can try this at home or in the classroom.) You'll hear from NHL players and coaches from the San Jose Sharks as well as leading physicists and chemists.

5 - TREASURES FROM K-12 INSTRUCTIONAL MEDIA CENTER: RIVERS, LAKES, SEAS, AND BAYS
http://www.k12imc.org/pg3108.cfm
Learn about the quality of natural water in your region or across the globe. From the Great Lakes to Chesapeake Bay to extensive canal systems, explore ecosystems, watersheds, weather, and more.
