A sixth-grader at Community House Middle School in North Carolina built a two-wheeled robot that steadies itself using proportional control. A seventh-grader in Florida is using math models to make ambulances arrive faster. An eighth-grader in Texas is hunting for molecules that could fight dementia. None of them are old enough to drive, but together they make up the 2026 class of Top 300 Junior Innovators — the brightest young minds in American science.
The Thermo Fisher Scientific Junior Innovators Challenge (JIC) is the country's top science, technology, engineering and math competition for middle school students, run by the nonprofit Society for Science. Its mission is simple but big: to inspire young scientists and inventors to take on the world's toughest problems. This year's Top 300 were chosen from 1,997 students who entered, and they come from 34 states, Puerto Rico and Guam.
These aren't your average school science projects. One student is using mushrooms to break down microplastics. Another designed a biodegradable fertilizer that releases nutrients when the soil gets wet. A young researcher in Miami is studying how the city's urban heat islands help an invasive lizard spread. Someone even built a wearable patch that could catch blood infections, called sepsis, early using DNA-triggered capsules.
The range of ideas is staggering — from mapping emergency services in Indianapolis to measuring star ages with astronomy diagrams to engineering seed coatings that help crops grow in salty soil. Each project tackles a real problem with real tools, from machine learning and data science to biochemistry and robotics.
The 30 finalists will be revealed on September 16)Skip — wait, the announcement is set for September 16, and those finalists will compete for more than $100,000 in prize money, including the top $25,000 Thermo Fisher Scientific ASCEND Award.
What makes this list so hopeful isn't just the prizes. It's the reminder that curiosity, creativity and a willingness to dig into hard problems aren't limited by age. Some of these students have even been named to the Top 300 before, marked with a small # next to their names — proof that they keep coming back to ask bigger questions.
As the finalists prepare to face off this fall, these 300 young innovators are showing the world that middle school is more than textbooks and tests. It's where the next generation of scientists is already solving problems, one bright idea at a time.
