Over two dozen rising high school juniors and seniors from around the country are at the University of Alabama this week to attend the Student Introduction to Engineering Camp.Known as “SITE,” the camp allows students to live on campus for a week, take classes and get hands-on experience with engineering. This year, campers are building t-shirt launchers out of PVC pipes.“They are taking the same three academic courses, they do engineering and design projects as I mentioned,” said Gregory Singleton, Director of Engineering Student Services. “[They take] seminars in all the fields of engineering. They learn about the University of Alabama. It is just a full week of learning about college life and what it takes to become an engineer.”The program is in its 28th year. This week’s session is the first of three this month.
