Pop, pop science 
The science news that my friends link to on Facebook is a mixed bag. Some of it's interesting, but lots of it is either junk or uncritical hype around new results.

There's some great science stuff on YouTube, however.

One great series is the Periodic Table of Videos, filmed by Brady Haran and hosted by Martyn Poliakoff. In addition to interesting tidbits of chemsitry, they put together a playlist which provides a guide to all the elements. Although I've been a fan for a while, this post was prompted by a recent video in which Sir Poliakoff expressed what philosophers would call realism about the periodic table. "What we're interested in is what nature is like," he says, "not how easy it is to draw."

While I'm at it, I'll also recommend Smarter Every Day. The host, Destin Sandlin, is an engineer who does some simple experiments but also finds experts on cool things to interview. His ecclectic interests include archery, animals, space, and what stuff looks like in slow motion. From his most recent video, I learned about devil facial tumor disease and the plight of the Tasmanian devil. Some YouTube slow-motion videos are just staged to be as spectacular, but Destin sets them up to illustrate the process he's filming; his video about tatooing, for example.

A few students from my summer course commented that they'd have preferred to have videos rather than so much reading. Although I don't think that I could use these videos to accomplish anything I use texts for, I do wonder if I could use them to warm students to a topic or get them to reflect on the popularization of science.
