The Deep Sea is a fascinating website designed by Neal Agarwal (@NealAgarwal). Neal has placed the creatures of the ocean at their typical depths, and you can scroll down from 18 meters at which you find Atlantic salmon and manatees all the way to the deepest part of the ocean at 10,901 meters deep. Little pieces of trivia are interspersed here and there, such as when you reach the point that is equal to the distance to the height of Mount Everest.
Students who are intrigued by the ocean and/or unique animals would love this site, and you can also integrate math with comparisons to other distances. For example the world’s current highest building, the Burj Khalifa, is 828 meters high. When you get to around that depth, you can find Giant Oarfish, which can grow to 11 meters long. Have students brainstorm ocean creatures they know and estimate where they might be found in “The Deep Sea.” To learn more about deep sea creatures that may or may not be on The Deep Sea site, check out this slideshow from the Smithsonian Institute that includes the frightening-but-cute yeti crab.

By the way, Neal Agarwal has a variety of other interactive sites that might interest you here. There’s a 3d “Design the Next iPhone” where you can not only drag and drop components that you want to had, but you can also create a video where your phone is “announced.” If you like the philosophical discussions generated by the classic “Trolley Problem,” try “Absurd Trolley Problems” for some macabre humor. And there’s more! I’m definitely adding his site to my “Fun Stuff” Wakelet. Although I must admit, comparing my hourly wage to other on the “Printing Money” site was not quite as fun…
