Pre-college summer camps are part of the successful recruiting efforts at Missouri S&T; The undergraduate enrollment at Missouri S&T has increased 23% in the past 10 years. This paper documents and describes the educational summer camp program developed for high school students. The overarching, broader impact goal of the summer camp is to introduce students to various engineering disciplines and help them to make a better decision on choosing a career or discipline within engineering. Several activities are designed to achieve the goal. The summer camp attracts about 300 to 400 high school students across the country every summer. This research study focuses on the hands-on activities offered by Missouri S&T, College of Engineering and Computer Science programs. Activity details in the Civil Engineering, Architectural Engineering and Environmental Engineering programs are described in this paper and the results are discussed. Students showed success in implementing the engineering principles into basic engineering problems through a problem-based learning activity. Students enjoyed the activities and showed improved learning after the hands-on program. A survey is also conducted at the end of the activity to understand the students' perception of the conducted activities and to enhance the program based on students feedback. Overall the summer camp was very positive for both the participants and their mentors.
