Oregon State University’s Summer Experience in Science and Engineering for Youth (SESY) is not free, but a 5 night science camp for $200 is one of the best deals you will find out there. My daughter did this for two years and had a wonderful time. Tuition assistance is available.
SESEY seeks to engage students, especially girls and minorities, in science and engineering by pairing them with graduate students to do lab work, listening to stimulating lectures, and having fun with about 80 other like-minded kids.
Applications are due May 13, 2012 with notification expected to be made on or around June 1. This year’s camp is from July 15-20.

The camp is sponsored by the College of Chemical, Biological and Environmental Engineering and most of the lab activities are with grad students in this school. Here are some happy campers with their lab mentor who helped them learn how to grow nano-tubes in a home made oven. Pretty good way to spend a week in summer, don’t you think?
Other highlights include lots of time to socialize with like-minded science geeks, a trip to the coast to visit the Hatfield Marine Science Center and a 5 days living like college students on the lovely Oregon State University campus.
