Cyber Discovery is a week-long immersion into all issues of cyber. It is a catalytic event for engaging students and teachers in the history of cyberspace, ethical and social issues, applications, and the need for and use of security in cyberspace. The experience includes discussion sessions, hands-on engineering and computer science labs, a cryptographic treasure hunt, creative story-telling, and a final cyber challenge. A microcontroller is a common thread that is woven throughout all projects to teach important concepts and fundamentals. Teachers from each school attend professional development workshops before leading their teams in week-long challenges. Cyber Discovery engages students through an intense, total immersive experience for high school teams.
