The nation’s largest STEM (science, technology, engineering and mathematics) celebration took place this past weekend at the Walter E. Washington Convention Center in Washington, D.C. The 5th USA Science and Engineering Festival featured more than 3,000 exhibits, 30 stage shows and attracted approximately 350,000 people. This year’s theme was “Where can STEM take you?” and the primary goal of the weekend was to inspire the thousands of kids in attendance.
