If you're interested in science in general, or in keeping track of the latest discoveries, the online versions of magazines are a great place to look. Discover Magazine has excellent articles written for laypeople, while Scientific American gets a little more into the technical details. Science Daily is a great place to catch up on breaking news in science. National Geographic covers more than just science, but its website has an excellent section devoted to science and nature. Public television networks are also great for science information. PBS has a science and nature section of their website, while the BBC (British Broadcasting Corporation) has separate sections for science and nature.
Science and natural history museums also have some great websites. Some of the best are the Smithsonian's National Museum of Natural History in Washington, DC, and the American Museum of Natural History in New York, home of the famous Hayden Planetarium. If you're especially interested in fossils, dinosaurs, and such, the University of California Museum of Paleontology has great online exhibits about the history of life on earth. The museum with the best online exhibits may be the Exploratorium in San Francisco, "The Museum of Science, Art, and Human Perception".
If you like watching videos about science and nature, the first place we recommend is one of the library's databases: Access Video on Demand, or AVOD. AVOD has thousands of streaming videos about all kinds of topics, including hundreds about science and nature. There are videos from BBC, PBS, Nova, National Geographic, Scientific American Frontiers, and more. If you like to hear great thinkers and scientists talk about their discoveries, TED offers hundreds of fascinating 20 minute lectures by some of the world's great minds, available for free online (and on AVOD). The people at TED have also launched a site for young people, called TED-Ed. TED-Ed's video are shorter than TED videos, and many of are beautifully animated. Here's one that explains just how small atoms are (they're really, really, really small).
The Open Culture website has links to all sorts of free educational material online. Their webpage on great science videos has enough links to free videos to keep a science buff entertained for weeks. Another great way to find science videos is to look at science channels on YouTube. National Geographic, Scientific American, and NASA all have channels with fascinating videos. If you or your kids like science experiments, Sick Science is a great channel to check out. Finally, Hulu has a page devoted to shows about science and technology. You may also be interested in their documentaries page.
Now let's look at a few of the best websites that focus on the different branches of science:
