What is Imaginology

Children, teens, families and school groups dig into science, technology, engineering, arts and math. Imaginology provides unique experiences for attendees of all ages – from preschool to high school, and their parents and grandparents – to build, create, play, observe and interact through activities that help them see the possibilities of a future in STEAM fields. Imaginology features makeshops, demonstrations, competitions, hands-on activities and entertainment, as well as food and fun. Youth competitions give students the chance to be recognized for their unique talent and accomplishments.
