I have a 9th grader who is really excited about modern physics and we're looking for a summer program where he can learn (and have fun learning) at the appropriate level. Most of the summer physics programs we've found are only open to current 11th or 12th graders. The Penn Experimental Physics Research Academy is one we've found that is actually open to 9th graders, and it sounds great - but it is very, VERY expensive and no financial aid is offered for non-residents. I was wondering if anyone had feedback about this camp? My son is in calculus this year and mathematically ready for work at a higher level, but he's also just a kid and likes to have fun and experiment with stuff - ideally we could find a camp with both. He did a camp for "gifted kids" last summer but it just didn't get very deep into the science or math - and while he had fun, he didn't learn anything. We're willing to pay for a great hands-on learning experience with expert instruction, but just want to know more about it before we make that investment.
