<p>I'll just comment---we sent my son to a summer program at U of Penn last year (in archeology). It really wasn't that informative, challenging or even all that interesting. It was for middle school kids, and the stuff was pretty elementary (e.g. digging in a sand pit for "fossils" the staff had placed there..). They also spent a lot of time playging ball games in the courtyard.</p>
<p>Not sure if this is the same program which was listed on the links above.</p>
<p>Drexel Engineering School has a great summer program, however (1 week). Drexel is a good school in Philadelphia.</p>
