This article describes summer programs that allow high school students to participate in an "authentic scientific research experience" (ASRE). These summer programs are specifically designed to embed students in working laboratories and research groups. Summer ASRE programs for secondary learners range in length from a couple of weeks to a few months, and typically are offered through universities. Program foci range from traditional STEM (Science, Technology, Engineering, and Mathematics) disciplines to more specific topics such as nanotechnology and biomedical engineering. Most of the programs are designed for rising high school juniors and seniors who are motivated in mathematics and science. Some are residential (students live in college dormitories) and can be costly. Participation in ASRE programs can result in positive outcomes for students interested in science-related futures, as participants can practice science in ways often not feasible in high schools.
