It's time to get the next generation of scientists thinking about what's important, and you can help. Below are five education challenges chosen by the editors of Popular Science in partnership with InnoCentive, an open-innovation and crowdsourcing firm. We invite you to devise a simple lesson plan for one or more of them. Each plan should be directed at middle-school students, involve at most three 50-minute sessions, and require less than $50 in materials.
Our friends at PopPhoto have compiled a gallery of the winners of Nikon's Small World photomicrography competition. Included are close-ups of a mosquito heart (above), a wasp's nest and more, in breathtaking detail. Check out the gallery and prepare to be amazed.
All right, smarty pantses, give this one a go. Lately, you brilliant DIYers have been making shortwork of our Guess This Tool contest, so we're going to mix it up a little and see if we can't stump you for more than 10 minutes. This is a tool of sorts, but it's in the early stages of a PopSci Dissection. As usual, the first and most precise answer in the comments will win something from our friends at Stanley: a FatMax 24-inch level. Good luck.
