On January 17—which happens to be Kid Inventors’ Day—the Lemelson Center launched the 3rd Annual Global Spark!Lab Invent It Challenge. Hosted in collaboration with the Smithsonian Center for Learning and Digital Access and ePals, the contest challenges children ages five to 18 to create an invention that solves a real-world problem. Alone or in groups, kids must work through the invention process, identifying a problem, researching possible solutions, sketching designs, building and testing prototypes, and creating ads to sell their ideas.
Though this may sound a little daunting, young inventors have access to lots of support on the Challenge website as they tackle their projects. Past winners, including Alexis Lewis, are serving as Student Ambassadors, answering questions and offering tips to their fellow inventors. Questions like “Where did you get your idea from?” and “How do you know if other people have done your invention?” have generated great advice from the Ambassadors already. Other message boards allow kids to share invention-related books and websites with one another, and even share their invention ideas to get feedback from their peers. (That board doesn’t have any traffic yet, though. I wonder if kids are fearful of their great ideas being stolen…)
As we await this year’s entries (the contest closes on April 11, 2014), here’s a look back at some of the most memorable inventions from the first two years. If these are any indication, this year’s Spark!Lab Invent It Challenge will generate a collection of inventions that are creative, innovative, fun, and inspiring.
