Check out the National Academy of Engineering’s  Grand Challenges K-12 Partners Program:

The Grand Challenge K-12 Partners Program will enlist colleges of engineering across the country to serve as community resources for K-12 students, teachers and administrators in their region. Partner colleges would develop age-appropriate engineering materials and curriculum, periodically host regional conferences, and provide ongoing support and professional development for teachers.
