CNN regularly produces two-to-three minute video clips on current news topics (including ones related to science) called “Explain It To Me.” They’re generally excellent.

The best way to find them is to type in “Explain It To Me” in the CNN search box, as I have done here. Then click on “CNN Videos” at the top of the page, and you’ll see titles and thumbnail images of them all.

Since I’ve already published a “The Best…” list for 2011 Social Studies sites, I’ll certainly be including “Explain It To Me” videos in next year’s list.
