'Tis the season for science fairs, when classrooms sprout cardboard jungles--and students sweat the details. Did you know this tradition only took root after 1942, with the first Science Talent Search? By now, science fairs are a high point of the school year around the country, and Google is launching a global online version (check out their amazing Rube Goldberg-like video). Projects need not be exotic to teach complex concepts. Let your Curious Georges monkey with bananas. See who gets DNA!

Lesson: Extract Banana DNA
In this lab activity, students in grades 5 through 9 use a salt/detergent mixture to make a piece of a banana water-soluble. Then they add cold ethanol to precipitate a froth of white DNA from the solution. With careful technique, the slender threads are wound onto a glass rod for observation of deoxyribonucleic acid, the blueprint of all organisms.
