I like the idea of perhaps exploring a summer program that might give her some insight into what might be involved in being an engineer and getting an engineering degree. I am sure there are closer options, however, this is one to check into:

It is not terribly expensive (around $575 for a week). She may need to to talk to her counselor about admission as it is for students identified as gifted or recommended by their GC. My D13 spent a week at SAHI for Human Anatomy with Histological Technic. It confirmed her love of the study of anatomy and actually helped her a bit in AP Biology. Ohio Northern qualifies as a smaller university (about 2700 undergrads) that has engineering. I know for sure they have Mech E and Civil E. It is in the middle of no where and definitely not an LAC.
