Every spring the same pressure arrives. Families want the summer to count, and the programs with the strongest names often carry the steepest fees. The good news is that price and quality do not move together as closely as the brochures suggest. Some of the most selective STEM summer programs for high school students are free, and several others cost less than a weekend trip.
This guide collects free and affordable STEM summer camps and programs in science, math, and engineering, both in person and online. It is organized by what a family will pay: free programs first, then low-cost options, then how STEM camp scholarships and financial aid work. It closes with what a camp gives a student and what research gives that a camp does not.
Each entry lists who the program is for, what it costs, and whether aid is available. Details were checked in October 2026, but fees and deadlines change, and several programs have not yet opened applications for summer 2027, so confirm on the official page before you plan.
Free STEM summer programs for high school students
Free does not mean lightweight. Several of the most selective programs in the country charge no tuition, though most have eligibility rules and limited places, so read the requirements before you get attached to one. If you are searching for free STEM summer camps, start here.
Carnegie Mellon University: Summer Academy for Math and Science (SAMS). A six-week residential program in Pittsburgh for rising seniors, meaning students who are juniors when they apply. Applicants must be at least 16 and U.S. citizens or permanent residents. Cost: free, with families covering travel and small personal expenses. Aid: the program is fully funded and merit-based, and the application asks for financial information. Applications close in winter, and published dates range from February 1 to March 1, so check CMU’s pre-college page for the current one. Details at cmu.edu.
MIT: MITES Summer and MITES Semester. Two free programs for rising seniors who are U.S. citizens or permanent residents. MITES Summer is six weeks on MIT’s campus, and MITES Semester is a six-month hybrid program that runs from June to December. Cost: free. MIT’s own FAQ says funders cover program costs and students pay only for travel to and from MIT. Aid: the program itself is the aid. Admission is selective, with a focus on students from underserved and underrepresented backgrounds. Applications open in the fall of junior year and close in winter. Details at mites.mit.edu.
Ohio State University: Camp CAR. A week-long day camp at Ohio State’s Center for Automotive Research for students entering 10th or 11th grade. Campers work on simulation, testing, and manufacturing, with field trips to a Honda wind tunnel and a vehicle test center. Cost: free. There is no overnight housing, so students from outside Columbus need to arrange their own lodging. Aid: not needed, but places are limited. Ohio State has reported roughly 100 applicants for 25 spots in a past year. Applications typically open in early spring. Details at car.osu.edu.
Student Conservation Association: Youth Programs. Conservation service crews for students ages 15 to 19, including residential National Crews of six to eight teenagers who spend several weeks working on public lands. Cost: National Crews are listed as no cost to participants, while some regional crews are paid positions. Details at thesca.org.
MathWorks Math Modeling (M3) Challenge. A team competition for high school juniors and seniors in the U.S. A teacher or coach registers a team of three to five students, and the team gets one 14-hour window over a late-winter weekend to model a real-world problem and write up its solution. Cost: no registration fee. Aid: scholarship prizes go to top teams, with the champion team’s prize listed at $20,000 split among its members. Registration closes in February. The write-up is useful practice for research writing. Details at m3challenge.siam.org.
NASA: Learning Space With NASA at Home. Hands-on space and engineering activities with video tutorials, sorted by grade band from kindergarten through 12th grade. Cost: free, with no application. The collection skews younger, so older teens will treat it as a supplement, not a summer plan. Details at jpl.nasa.gov.
Georgia Tech: Introduction to Engineering Mechanics (Coursera). A self-paced online course on statics, taught by Georgia Tech faculty. Cost: free to audit, which opens most course materials. Graded assignments and a certificate cost extra. Aid: Coursera offers financial aid on select courses, through a link on the course page. Details at coursera.org.
UC Davis: Materials Science, 10 Things Every Engineer Should Know (Coursera). A self-paced online course of about eight to nine hours with no prerequisites, covering how materials behave and why engineers choose them. Cost: free to audit, with graded work and a certificate available for a fee. Aid: Coursera financial aid on select courses. Details at coursera.org.
A note on search: the much broader query “free summer programs for high school students” returns options in every subject and location. This guide stays with STEM.
Programs focused on robotics and aerospace are covered in more depth in our guides to 15 robotics summer programs for high school students in 2026 and 15 aerospace and aeronautics summer research programs for high school students.
Low-cost STEM summer camps
If the free programs are full or do not fit your student’s interests, these options keep costs modest.
Indiana University: Jim Holland Summer Science Programs. Three programs on the Bloomington campus: the Summer Enrichment Program in Biology, the Summer Science Research Program, and the Research Initiative in STEM Education. The enrichment program is a week-long residential program with lectures, discussion, and lab work, for students entering grades 9 to 11 with at least a 3.0 unweighted GPA. The programs are aimed at students from underrepresented backgrounds in science. Cost: accepted students pay a $125 non-refundable registration fee. Aid: the program page does not mention aid, so ask the program office about it. Applications for 2026 are closed, and 2027 dates were not posted at the time of writing. Details at biology.indiana.edu.
Rube Goldberg Institute for Innovation and Creativity Contests. Contests for students from elementary school through high school, with a high school division for grades 9 to 12. Students build an intentionally overcomplicated machine that completes a simple task. Cost: the online contest, where teams submit a video, charges a $10 submission fee. Live regional contests are run by local hosts, who set their own registration terms, and teams must register in advance. Aid: ask the regional host. Details at rubegoldberg.org.
Art of Problem Solving. Math texts and online courses for students in grades 5 to 12, aimed at strong problem solvers. Cost: some resources, such as its Math Jams contest reviews and Q&A sessions, are free, while classes are paid and priced per course, so check the current schedule for the course you want. Aid: AoPS does not advertise it on its main school page, so ask directly before enrolling. Details at artofproblemsolving.com.
edX: MITx Circuits and Electronics 1: Basic Circuit Analysis. A self-paced MIT course that takes about five weeks at five to six hours a week. It assumes high school algebra, basic calculus, and introductory electricity and magnetism, so it suits strong juniors and seniors best. Cost: free to audit, with a paid verified certificate. Listings show prices from $169 to $189, so confirm the current figure on edX. Aid: confirm on the course page. Details at edx.org.
A practical tip: low-cost does not have to mean low-commitment. A finished course or competition entry gives a student something specific to point to later.
STEM camp scholarships and financial aid
Families searching for STEM camp scholarships or STEM camp financial aid are usually asking one of two questions: which programs cost nothing, and how to get help with the ones that charge.
For the first, some of the strongest programs are already fully funded. CMU’s SAMS and MIT’s MITES cover tuition and, for the residential programs, housing and meals, and Camp CAR is free. For a student who meets the eligibility rules, these are worth applying to before any paid program, and families should plan for travel, which is usually the one cost left.
For paid programs, start on the program’s own page and look for the words “financial aid,” “fee waiver,” “scholarship,” or “sliding scale.” Some programs publish aid terms and others discuss them only when asked, so a short email to the program office is worth sending. Ask what aid exists, what documents are required, and whether aid is decided with admission or separately. For online courses, Coursera lets learners apply for financial aid on select courses through a link on the course page.
Timing matters. Among the programs here, applications close between roughly January and April, and some open in the fall, so start the search in autumn. Where a program allows it, apply for aid at the same time as the program.
School counselors and local community organizations can also point to additional summer funding, so ask about aid before ruling a program out on price.
Finally, pair options. A student might apply to one selective program and also line up a free self-paced course or a competition entry, so the summer does not depend on a single decision.
Camp or research: what each gives a student
Camps and research projects are not competing choices. They do different jobs.
A camp gives a student exposure. In a few weeks, a student can try coding, robotics, or lab science, meet others who share the interest, and find out what they enjoy or do not. It is the right choice for a student who is still exploring, and usually the lower-risk and lower-cost way to test an interest.
Research gives a student something to show. A research project means working on an original question, usually with a mentor, and producing a paper, a poster, or a competition entry that belongs to the student. That is a different kind of record from a camp certificate, and it tends to stand out in applications and science competitions. It also takes longer and asks for more independence.
A useful rule is to use a camp to find the question, then use research to answer it. A student who attends a robotics camp in June and discovers an interest in autonomous navigation has a much stronger starting point for a research project than a student who begins from nothing.
If your student already knows what they want to explore, our summer research program pairs students with PhD mentors to build a project from the ground up. For help deciding which path suits your student, our guide to research and internship options for high school students walks through what each looks like in practice.
