A high school research project looks like a student picking one narrow, measurable problem, designing a test or prototype, running it with guidance from an expert, and reporting results others can check. The five real projects below show this at work, from a $0.03 cancer test to a magnet-free EV motor.
Every year, roughly 2,000 students from 60+ countries compete at the Regeneron International Science and Engineering Fair, the largest pre-college science competition in the world. Most projects are impressive. A handful are something else entirely: research that identifies a gap professional scientists hadn’t closed, proposes a testable solution, and produces findings rigorous enough to earn recognition from industry and academia alike.
These five projects cleared that bar before their creators turned 18.
A $0.03 Test for Pancreatic Cancer
Category: Medicine & Health Sciences | Award: Gordon E. Moore Award, $75,000 (Intel ISEF 2012)
The question: Can early-stage pancreatic cancer be detected with a test cheap enough for routine screening?
The method: A paper biosensor of carbon nanotubes and antibodies targeting mesothelin, read with a $50 ohmmeter.
The result: A $0.03 test returning results in five minutes with 90%+ accuracy detecting mesothelin.
What it would take to attempt something similar: A lab with nanomaterial and antibody expertise (this sensor was refined in a Johns Hopkins lab), plus an ohmmeter and a way to test blood samples.
The Problem
Pancreatic cancer is one of the deadliest cancers largely because it is rarely caught early. The American Cancer Society’s 2026 figures put the five-year survival rate at 13% overall, 44% when the cancer is still localized to the pancreas, and 3% once it has spread to distant organs. At the time of this project, the standard detection method (ELISA) cost up to $800 per run, took about 14 hours, and required trained lab technicians. Routine screening was economically impossible.
The Approach
The project developed a paper biosensor using single-walled carbon nanotubes and antibodies targeting mesothelin, a protein overexpressed in early-stage pancreatic cancer. Filter paper was dip-coated with the nanotube-antibody mixture, making it electrically conductive. When a blood sample containing mesothelin was applied, the antibodies bound to the protein, expanding the molecular complex and increasing resistance across the nanotube network. That resistance change, measurable with a $50 ohmmeter, correlated directly to mesothelin concentration. The test required 1/6 of a drop of blood.
Why It Mattered
According to the student’s ISEF results, the sensor cost $0.03 per run and returned results in five minutes, 168 times faster and 26,667 times cheaper than ELISA, with 90%+ accuracy detecting mesothelin above diagnostic threshold levels. A provisional patent was filed, and Smithsonian Magazine gave the project a 2012 American Ingenuity Award. The project sparked broader conversation about what low-cost biosensor design could look like across cancer diagnostics.
The Scale Signal
Early detection is where the survival gap shows: 44% five-year survival when pancreatic cancer is localized, against 3% when it has spread. The American Cancer Society estimates about 67,530 US diagnoses and 52,740 deaths from the disease in 2026. The $0.03 test made a case that cost was a solvable variable, not a fixed constraint.
A Room-Temperature Ebola Test Built on Silk
Category: Biomedical & Health Sciences | Award: Google Science Fair Grand Prize, $50,000 (2015)
The question: Can an Ebola diagnostic work without refrigeration, electricity, or a lab technician?
The method: A single-use assay card that uses silk fibroin to hold the reagents for a lateral-flow antigen test.
The result: A $25 card that detected control Ebola antigens in the lab in 30 minutes and stayed stable at room temperature for up to one week.
What it would take to attempt something similar: Advice from scientists who know silk fibroin (this student worked with two Tufts University scientists) and access to the reagents for an antigen test.
The Problem
During the 2014–2015 West African Ebola outbreak, the limiting factor wasn’t treatment, it was diagnosis. Existing ELISA-based Ebola tests required uninterrupted refrigeration from manufacture to deployment, cost hundreds of dollars per test (up to $1,000 by the student’s estimate), and took up to 12 hours to produce results. In rural communities in Guinea, Sierra Leone, and Liberia, where the outbreak was most acute, reliable electricity and cold-chain logistics were both scarce. Patients were often contagious before a diagnosis was confirmed.
The Approach
The project developed a portable, single-use Ebola Assay Card (EAC) using silk fibroin, a protein derived from silkworm cocoons with exceptional stabilizing properties, to embed the biochemical reagents required for lateral-flow Ebola detection. Silk eliminated the need for refrigeration, allowing the card to remain stable at room temperature for up to one week. The card required only a sample and water to activate: a color-change readout confirmed positive or negative Ebola antigen detection within 30 minutes. No electricity, no lab technician, no cold chain.
Why It Mattered
The test cost $25 and detected Ebola viral antigens within 30 minutes, compared with the student’s estimate of up to $1,000 and 12 hours for existing ELISA-based methods. The silk stabilization approach was developed with advice from two Tufts University scientists, Fiorenzo Omenetto and Benedetto Marelli, who had developed the liquid silk formulation, and the student used the university’s Silklab laser cutter. The project began in her high school science research class. The card was shown to detect control Ebola antigens in the lab, not samples from Ebola patients, so it is a proof of concept rather than a field-tested diagnostic. The student noted the framework could be adapted to other diseases including HIV, Dengue, Lyme disease, and Yellow Fever: the silk stabilization logic is not Ebola-specific.
The Scale Signal
The project addressed a structural failure in outbreak response infrastructure: tests that require cold chains can’t reach the communities that need them most. The EAC design inverted that constraint, the test could be manufactured centrally, shipped at ambient temperature, and administered in the field with minimal training.
A Pocket-Sized Lead Detector, Built by an 11-Year-Old
Category: Environmental Engineering | Award: Discovery Education 3M Young Scientist Challenge, $25,000 (2017)*
Note: The 3M Young Scientist Challenge is a parallel national competition for middle school students (grades 5–8), distinct from ISEF. It is included here because the project’s technical and scientific merit warrants it, and because it remains one of the most widely recognized examples of middle school-level research producing real-world applicable technology.
The question: Can a household device detect lead in drinking water in real time, without a lab?
The method: A 3D-printed, deck-of-cards-sized device with a carbon nanotube cartridge, an Arduino signal processor with Bluetooth, and a paired smartphone app.
The result: A working prototype, Tethys, that reports safe or unsafe in real time to anyone, with no scientific training.
What it would take to attempt something similar: A mentor in sensors (this student worked with 3M scientists over a summer), a 3D printer, an Arduino, and a phone app.
The Problem
As the Flint, Michigan water crisis made visible, lead contamination in drinking water is not a historical artifact, it affects more than 5,300 water systems in the United States, according to 2016 data. Existing home testing methods were slow, unreliable, and required samples to be sent to a lab. There was no portable, real-time consumer device for lead detection.
The Approach
The project produced Tethys (named for the Greek Titan goddess of fresh water): a compact, 3D-printed device about the size of a deck of cards containing a disposable cartridge of chemically treated carbon nanotube arrays, an Arduino-based signal processor with Bluetooth, and a paired smartphone app. The carbon nanotubes are sensitive to changes in the flow of electrons; the tubes are lined with atoms that have an affinity to lead, which adds a measurable resistance to the electron flow. When the cartridge is dipped in contaminated water, the lead-reactive atoms bind to lead ions, creating resistance in the electron flow. The Arduino processor measures that resistance and transmits results to the app in real time: safe or unsafe, immediately readable by anyone.
Why It Mattered
Over the course of the summer, the inventor worked with 3M scientists to bring the proposed sensor from a cardboard prototype to a functioning device with 3D-printed hardware and working software. The project attracted coverage from NPR and Business Insider, and led to a partnership with Denver Water’s lab team to test and refine the sensor, including how other chemicals in water interfere with it. The inventor was named to the 2019 Forbes 30 Under 30 list at age 13, before reaching high school.
The Scale Signal
Traditional lead testing requires sending a water sample to a lab and waiting days for results. Tethys was designed to move that timeline to seconds and to be used by people with no scientific training, in their own homes. It remained a prototype, and the student estimated a finished kit could cost $20 or less.
A Magnet-Free EV Motor, Built from 3D-Printed Plastic and Copper Wire
Category: Engineering — Electrical | Award: George D. Yancopoulos Innovator Award, $75,000 (Regeneron ISEF 2022)
The question: Can a synchronous reluctance motor, which uses no rare-earth magnets, deliver competitive torque for vehicles?
The method: A redesigned rotor with an added magnetic field, built from 3D-printed plastic, copper wire windings, and steel, and tested with a laser tachometer and power meters.
The result: A 39% increase in torque and a 31% increase in efficiency at 300 RPM, measured against a conventional synchronous reluctance motor.
What it would take to attempt something similar: Over a year of iterative development and access to testing instruments such as a laser tachometer and power meters.
The Problem
The dominant electric vehicle motor design relies on rare-earth permanent magnets — neodymium, samarium, dysprosium — that are expensive to source, environmentally damaging to mine, and geopolitically concentrated: China produced about 69% of the world’s mined rare earths in 2025, according to the US Geological Survey. The EV industry’s sustainability case has a supply chain problem at its center. Synchronous reluctance motors (SynRMs) had long been understood as a magnet-free alternative, but their torque and efficiency weren’t competitive with permanent magnet motors for vehicle-grade applications.
The Approach
The project set out to redesign the synchronous reluctance motor to improve torque at vehicle-relevant speeds. Standard SynRMs use a steel rotor with air gaps cut into it that aligns with a rotating magnetic field, the magnetism of the steel generates torque, and more torque is produced when the saliency ratio (the difference in magnetism between the steel and the non-magnetic air gaps) is greater. Instead of relying only on air gaps, the project introduced an additional magnetic field into the rotor design, the specific mechanism was withheld pending patent consideration. The prototype was built from 3D-printed plastic, copper wire windings, and a steel rotor, tested with a laser tachometer and power meters over a year of iterative development.
Why It Mattered
The prototype increased torque by 39% and efficiency by 31% at 300 RPM, compared with a conventional synchronous reluctance motor the student built for comparison. Efficiency gains reached 37% at 750 RPM, but the 3D-printed plastic prototype melted at higher speeds. Smithsonian Magazine covered the project; engineering publications noted that BMW and MAHLE are pursuing magnet-free motor development for identical supply-chain reasons. The work demonstrated a viable design direction for a problem that professional electrical engineers are actively trying to solve, from a 17-year-old’s year-long project.
The Scale Signal
The International Energy Agency’s 2025 outlook projected that electric cars could reach 40% of global new car sales by 2030 under current policies; its 2026 outlook puts the 2025 share at about 25% and expects close to 30% in 2026. Every vehicle using rare-earth magnets is a node in a supply chain with known fragility and environmental costs. A manufacturable magnet-free motor at competitive torque would remove that dependency entirely.
A Chemical Doping Strategy That Could Change What’s Possible Inside the Human Body
Category: Materials Science | Award: George D. Yancopoulos Innovator Award, $75,000 (Regeneron ISEF 2024)
The question: Can chemical doping make n-type organic electrochemical transistors stable and fast enough for use in biological environments?
The method: Introducing organic salts into the polymer channel, then characterizing results with current-voltage tests and electrochemical impedance spectroscopy.
The result: Tetrabutylammonium chloride gave a 97% increase in amplification and a 77% increase in electrical signal mobility.
What it would take to attempt something similar: Roughly six months of work and access to equipment for current-voltage and electrochemical impedance testing.
The Problem
Organic electrochemical transistors (OECTs) represent one of the most promising frontiers in biomedical technology: flexible, organic devices that can interface with biological tissue in ways rigid silicon electronics cannot. Researchers have been developing them for deep brain stimulators, pacemakers, biosensors, and artificial muscles. The problem blocking commercialization is performance — specifically, n-type (electron-conducting) OECTs suffer from instability in biological environments and slow signal transmission. No viable solution had been identified.
The Approach
The project investigated chemical doping as a method to improve OECT performance: introducing organic salt compounds to alter the molecular structure of the transistor’s polymer channel, then characterizing the results using current-voltage tests and electrochemical impedance spectroscopy. Four organic salts were tested to determine their impact on device performance. The research revealed that one particular salt — tetrabutylammonium chloride — significantly improved the performance of OECTs. The findings demonstrated a 97% increase in amplification abilities, a 77% increase in electrical signal mobility, and enhanced sensitivity and signal-to-noise ratio.
Why It Mattered
OECTs are among the most powerful transistors to date, combining both ionic and electronic conduction, a mechanism that makes these devices desirable for implantable bioelectronics in the human body, particularly as biosensors, deep brain stimulators, pacemakers, and artificial muscles, reducing reliance on invasive medical procedures. Ian Jandrell, a judging co-chair for materials science at ISEF, told Business Insider “this was our number one project, without a shadow of a doubt,” and said the judging room was convinced it deserved a top award. The student described the approach as simple and low-cost: it adds a salt to the polymer rather than requiring a new material.
The Scale Signal
Bioelectronics researchers have spent years trying to make OECTs stable enough to implant. A 97% improvement in amplification and a 77% increase in electrical signal mobility, achieved through a simple, inexpensive chemical treatment, is a meaningful step toward clinical viability for devices that could eventually monitor glucose, regulate heartbeat, or stimulate neural activity without traditional surgical hardware.
How to turn these examples into your own research project
Turn these examples into your own project by doing what these students did: define a specific, measurable gap, get expert help and resources beyond the classroom, and treat the competition as a milestone rather than the starting point.
Start with a gap, not a topic. Each project identified a specific, measurable gap. “Cancer is bad” is a topic. “There is no screening method that costs under $5 and returns results in under an hour” is a research problem. That second kind of framing is what made it possible to design a test, build a prototype, and produce findings that could be evaluated against a standard. Our guide on how to pick a research topic for science fair and competition shows how to narrow an interest into a question like that.
Get mentorship and resources. The pancreatic cancer sensor was refined in a Johns Hopkins lab. The Ebola assay card was developed with advice from Tufts scientists. The lead detector was built with 3M scientists. The motor took a year of sustained work, and the doping research about six months.
Plan the time. In every case, the competition was a milestone, not the starting point. The research came first, and it took a summer or more. How long a student research project really takes breaks the timeline into stages for middle and high school students.
Choose a field with open problems. These five categories, medicine, biomedical, environmental engineering, electrical engineering, and materials science, are each fields with significant talent demand and decades of open research problems ahead. A student who arrives at a university having done rigorous work in any one of them doesn’t just stand out in an application, they arrive with a research identity already formed. For more starting points, see these robotics, AI, software, and embedded systems project ideas and these biology, medicine, and health topics for STEM research and science fair competitions.
If your student has a specific problem they keep returning to, that’s where research begins. The rest is structure, access, and time.
Questions students and parents ask
What counts as a research project for a high school student?
A research project asks a specific question, uses a defined method to gather evidence, and reports a result. A project that only summarizes existing information, or builds something without testing a question, is a report or a build.
Does a high school student need a lab or a mentor to do research?
Not always a lab, since computational, survey-based, and data-analysis projects can run on a laptop. A mentor matters more than equipment, because someone experienced can catch flawed methods early. The pancreatic cancer, Ebola, and lead detector projects above all had expert help beyond the classroom.
How long does a high school research project take?
It takes months, not weeks. In this article, the lead detector was built over one summer and the motor was developed over a year of iteration.
How do students choose a research topic?
Start from a real interest, then narrow it to a measurable gap that can be tested with the time and resources available.
