WASHINGTON, D.C. — When it comes to rockets, the more thrust the better. This week, Eleanor Sigrest rocketed through a series of science, engineering and math challenges in the nation’s capital. On November 1, she claimed the top prize, an educational award worth $25,000.
The 13-year old from Woodbridge, Va., learned of the honor at an awards gala the night after Halloween. And for Eleanor, it was no trick, all treat. “When I first learned that I’d won, I didn’t quite believe it,” she says. “Everyone else was just as deserving,” she adds modestly.
Eleanor was one of 30 finalists from 15 states in the sixth annual Broadcom MASTERS competition. (MASTERS stands for Math, Applied Science, Technology and Engineering for Rising Stars.) The program was created by Society for Science & the Public (SSP), which publishes Science News for Students. The Samueli Foundation provided Eleanor’s winnings. This non-profit organization was created by Broadcom founder Henry Samueli.
Overall, a dozen finalists took home major cash awards or funding to attend the science camp of their choice.
Students qualified to take part in the competition on the basis of a middle-school science fair project. Those projects fall within the fields of science, technology, engineering or mathematics (STEM). Finalists had to be in the sixth, seventh or eighth grades when they competed at the local level. Broadcom MASTERS is much more than a science fair, however. Indeed, the contestants’ qualifying projects accounted for only about one-fourth of their total scores.
In her qualifying project, Eleanor analyzed the best shape for a rocket nozzle. Based on previous research, designers have long presumed the best angle between the nozzle’s axis and its surface is 15 degrees, she notes. For her study, she 3-D-printed tiny plastic models of rocket nozzles. Some had wide angles. Others nozzles were narrower, with the angle between the nozzle’s surface and its central axis as low as 12 degrees.
The teen forced compressed air through each nozzle and compared the findings. And the results surprised her: “I found the best angle for a rocket nozzle is about 20 degrees,” she says. The findings, she suspects, might argue that engineers should re-evaluate their designs in some cases.
“I would like to congratulate Eleanor, our top 2016 Broadcom MASTERS winner,” says Maya Ajmera. She adds that “I’m excited to see where her interest in STEM takes her." Ajmera is president of SSP, which publishes Science News for Students.
The largest portion of Eleanor’s winning score came from her performance in a series of science challenges. Even before arriving in Washington, she and the other finalists had been grouped into five-member teams. For two days of the competition, each team designed everything from electronic circuits to games that teach users about nutrition. One challenge asked each team to design and build a robotic arm. It was to be based on a crab’s arm and claw.
Altogether, the 30 finalists competed for more than $100,000 in awards. This year’s group of finalists included an even split of 15 girls and 15 boys. They had been selected from the more than 2,300 applicants that had entered this year’s competition. That group came from 49 states and 4 U.S. territories. The field was narrowed to 300 semifinalists and then the 30 finalists.
“Through this competition, we are cultivating a group of young scientists who will someday address many of our global challenges,” says Ajmera.

Paula Golden is president of the Broadcom Foundation, based in Newport Beach, Calif. This organization sponsored the MASTERS competition and provided funding for its awards. “Celebrating the success of our 2016 Broadcom MASTERS winners gives us a chance to acknowledge the hard work and dedication of young people everywhere,” said Golden. She lauded the young researchers, who, she notes, “are pursuing their dreams to become scientists, engineers and innovators.”
acidification A process that lowers the pH of a solution. When carbon dioxide dissolves in water, it triggers chemical reactions that create carbonic acid.
angle The space (usually measured in degrees) between two intersecting lines or surfaces at or close to the point where they meet.
annual Adjective for something that happens in every year. (in botany) A plant that lives only one year, so it usually has a showy flower and produces many seeds.
app Short for application, or a computer program designed for a specific task.
axis The line about which something rotates. On a wheel, the axis would go straight through the center and stick out on either side. (in mathematics) An axis is a line to the side or bottom of a graph; it is labeled to explain the graph’s meaning and the units of measurement.
brain scan The use of an imaging technology, typically using X rays or a magnetic resonance imaging (or MRI) machine, to view structures inside the brain. With MRI technology — especially the type known as functional MRI (or fMRI) — the activity of different brain regions can be viewed during an event, such as viewing pictures, computing sums or listening to music.
Broadcom MASTERS Created and run by the Society for Science & the Public, Broadcom MASTERS (Math, Applied Science, Technology and Engineering Rising Stars) is the premier middle school science and engineering fair competition. Broadcom MASTERS International gives select middle school students from around the world a unique opportunity to attend the Intel International Science & Engineering Fair.
carbon The chemical element having the atomic number 6. It is the physical basis of all life on Earth. Carbon exists freely as graphite and diamond. It is an important part of coal, limestone and petroleum, and is capable of self-bonding, chemically, to form an enormous number of chemically, biologically and commercially important molecules.
circuit A network of that transmits electrical signals. In the body, nerve cells create circuits that relay electrical signals to the brain. In electronics, wires typically route those signals to activate some mechanical, computational or other function.
degree (in geometry) A unit of measurement for angles. Each degree equals one three-hundred-and-sixtieth of the circumference of a circle.
depression A mental illness characterized by persistent sadness and apathy. Although these feelings can be triggered by events, such as the death of a loved one or the move to a new city, that isn’t typically considered an “illness” — unless the symptoms are prolonged and harm an individual’s ability to perform normal daily tasks (such as working, sleeping or interacting with others). People suffering from depression often feel they lack the energy needed to get anything done. They may have difficulty concentrating on things or showing an interest in normal events. Many times, these feelings seem to be triggered by nothing; they can appear out of nowhere.
detergent A compound derived from petroleum products, often used for cleaning. Detergents work by breaking up and surrounding dirt particles or oily substances, so that they can be washed away with water.
engineering The field of research that uses math and science to solve practical problems.
forge (noun) A furnace or shop where metal is worked and turned into new materials. (verb) To shape metals under heat and/or pressure, or (colloquially) to form one element from another under the intense heat and pressure inside stars.
innovation (v. to innovate; adj. innovative) An adaptation or improvement to an existing idea, process or product that is new, clever, mo re effective or more practical.
muscle A type of tissue used to produce movement by contracting its cells, known as muscle fibers. Muscle is rich in a protein, which is why predatory species seek prey containing lots of this tissue.
nozzle A round spout or slot at the end of a pipe, hose or tube. Nozzles are typically used to control the flow of a jet of high-pressure liquid or gas.
nutrition (adj. nutritious) The healthful components (nutrients) in the diet — such as proteins, fats, vitamins and minerals — that the body uses to grow and to fuel its processes.
plastic Any of a series of materials that are easily deformable; or synthetic materials that have been made from polymers (long strings of some building-block molecule) that tend to be lightweight, inexpensive and resistant to degradation.
pollutant A substance that taints something — such as the air, water, our bodies or products. Some pollutants are chemicals, such as pesticides. Others may be radiation, including excess heat or light. Even weeds and other invasive species can be considered a type of biological pollution.
polymer A substance made from long chains of repeating groups of atoms. Manufactured polymers include nylon, polyvinyl chloride (better known as PVC) and many types of plastics. Natural polymers include rubber, silk and cellulose (found in plants and used to make paper, for example).
risk The chance or mathematical likelihood that some bad thing might happen. For instance, exposure to radiation poses a risk of cancer. Or the hazard — or peril — itself. Among cancer risks that the people faced were radiation and drinking water tainted with arsenic.
rocket Something propelled into the air or through space, sometimes as a weapon of war. A rocket usually is lofted by the release of exhaust gases as some fuel burns. (v.) Something that flings into space at high speed as if fueled by combustion.
Society for Science and the Public (or SSP ) A nonprofit organization created in 1921 and based in Washington, D.C. Since its founding, SSP has been not only promoting public engagement in scientific research but also the public understanding of science. It created and continues to run three renowned science competitions: The Regeneron Science Talent Search (begun in 1942), the Intel International Science and Engineering Fair (initially launched in 1950) and Broadcom MASTERS (created in 2010). SSP also publishes award-winning journalism: in Science News (launched in 1922) and Science News for Students (created in 2003). Those magazines also host a series of blogs (including Eureka! Lab).
STEM An acronym (abbreviation made using the first letters of a term) for science, technology, engineering and math.
technology The application of scientific knowledge for practical purposes, especially in industry — or the devices, processes and systems that result from those efforts.
thrust A force that makes an object move forward.
