Sparticl is a new web and mobile service for teens, a collection of the very best the web has to offer in science, technology, engineering, and math or STEM. Sparticl includes answers to science questions, images, videos, games, and hands-on activities, all curated by a team of experts. But it's also a place where teens play a critical part - ranking content, sharing it, and recommending new content, all the while earning points and badges.
