The deadline for your 5th-8th science students to get their video application in for the Discovery/3M Young Scientist Challenge is exactly 2 weeks away. In addition to the little pep talk from Will Smith on their main page, we’ve scheduled a webinar with ’08′s Young Scientist of the Year, Melissa Rey. You can get one last round of tips on how to polish that video entry and also hear from an extraordinary young lady who was tops in the nation last year. Register here for her May 13th webinar at 1:00 p.m. EDT and check out the four challenge topics that could make a difference around the house. Choose just one of them and make a video illustrating a solution to enter.
