JPL Education ‘Teachable Moment’ Inspires Winning Science Fair Project
By Kim Orr
Joshua Dove, 13, used an educational activity from NASA’s Jet Propulsion Laboratory as inspiration for his winning science fair project.
A “teachable moment” turned into a science fair win for an eighth-grader in Ontario, Canada, who based his project on a classroom activity from NASA’s Jet Propulsion Laboratory.
Joshua Dove, 13, says he originally planned to explore the effects of storage temperature on golf balls until his grandfather, a space enthusiast and environmental consultant, saw a Caltech news story he had to share.
The story was about how an instrument called LIGO had detected gravitational waves for the first time, confirming a key piece of Einstein’s 1915 general theory of relativity. A web search led Dove to the JPL Education website and its “Dropping In With Gravitational Waves” activity, where he learned how to model the gravitational wave discovery using gelatin, a laser and marbles.
“Scientific models allow scientists, and students, to understand and explain phenomena that might be difficult or impossible to see,” said JPL Education Specialist Lyle Tavernier, who created the lesson for the website’s Teachable Moments blog. The blog, from the JPL Education Office, helps educators turn NASA- and JPL-related mission and science news into activities for the classroom. “While the LIGO detectors are located thousands of miles apart, this activity helps students understand gravitational waves using a model that fits on their desk!”

Dove made modifications to the JPL Education activity for his science fair project, including using Legos to create a device that could drop a marble from different heights. He says figuring out how he needed to alter the design was his favorite part of the project.
With the help of his mom and grandfather plus a few tips from Tavernier, Dove was able to modify the lesson for his science fair project, which looked at whether the model would show consistent and predictable variations in the movement of the laser (gravitational waveform) depending on the energy released during a marble (black hole) collision.
“There was a trend that suggested the greater the weight of the impacting object, the larger the amplitude of the waveform,” said Dove, noting in his abstract that there were some inconsistencies in the results that would require more testing. He plans to do that this summer.
After presenting at his school’s science fair, Dove was asked by his teacher to enter the regional competition, where he won an award from the Royal Astronomical Society of Canada.
Dove’s mom says the win was a big confidence booster for her son, who hopes to eventually work at NASA or become an inventor. “I would like to invent things that would help people affected by a natural disaster,” he said.
As far as advice for other science fair participants, Dove says, “Don’t be upset if you don’t get the results you are expecting, and don’t be afraid to make modifications to your experiment.” In fact, he says it was working through the modifications that turned out to be his favorite part of the project.

His other advice: “Have a good mentor.” Or in Dove’s case, three. In addition to support from his grandfather and mom, it was Dove’s older sister, a science fair winner herself, who encouraged him to enter the regional competition. And thanks to the encouragement, Dove has no plans to stop now. “I would like to learn more about detecting other intergalactic phenomenon,” he said.
