The Intel International Science and Engineering Fair (ISEF) is an annual event designed to show off the best of high school science from around the world. Sponsored by Intel—which also sponsors the Science Talent Search whose past finalists we started profiling—it draws 1,500 students from 51 countries to a host city to show off their work. The kids compete for $4 million in scholarships and awards.

In this slide show, take a tour of what we saw—from kudzu-based biofuels to robots to an air battery. For all of our posts, see this story.
