ARKive features photos and video footage of "15,000 of the world’s endangered species. With over 100,000 photos and videos, discover what these animals, plants and fungi look like, what makes them special and why we should protect them."
All of us overestimate our ability to multitask, and drivers are no exception. Despite what you might think, you cannot write a love letter and listen in class at the same time. Texting and driving is the same. The New York Times has developed a game to prove it.
Beautifully illustrated and designed, this gorgeous reference book explores the world of trees from every perspective—from the world's great forests to the lifespan of a single leaf. Arresting color photographs of a wide variety of trees and close-ups of many of their remarkable features provide an enormous amount of information in a highly accessible format. The volume illustrates how trees grow and function, looks at their astounding diversity and adaptations, documents the key role they play in ecosystems, and explores the multitude of uses to which we put trees—from timber and pharmaceuticals to shade and shelter. A highly absorbing read cover to cover or dipped into at random, Trees: A Visual Guide delves into many specific topics: the details of flowers, bark, and roots; profiles of favorite trees; how animals and insects interact with trees; trees in urban landscapes; the role trees play in our changing climate; deforestation and reforestation; and much more.

Attractive and functional, this is the best online periodic table I've seen. As you scroll over each element, it shows some details, and if you click on the element, it provides a thorough and interesting collection of links examining the element in even more detail. Produced by the Royal Society of Chemistry, it has to be good.
If you are into math or science at ALL, you need to be familiar with WolframAlpha. More than a search engine, WolframAlpha calculates the answers to math or science questions, creates plots, converts units, efficiently accesses scientific data and statitistics, and lots more. It took me awhile to get used to it because it is different than a regular search engine, but it is very, very useful.
WolframAlpha also has some unexpected breadth. I enjoyed floating around in the Wolfram Demonstrations Project. I doubt I'll ever get my mind around all that WolframAlpha offers, but I plan to enjoy trying. (MHouse)
