Applying science
Navajo Times | Adron Gardner The Navajo Nation middle and high school division science fair kicks off with 250 entrants March 2 at Red Rock Park.
Science fair winners tend toward the practical
CHURCH ROCK, N.M.
When Kelly Charley, senior at Navajo Preparatory School in Farmington, New Mexico, isn’t living in the dorms, she is at home in Teec Nos Pos with her grandparents.
Being raised by her grandparents, Charley knows all too well how much work goes into keeping their home warm. When she is home, she is either chopping wood or bringing in coal, but when she’s not there to do the chore, her grandparents must complete the arduous task themselves. This gave her an idea for a science fair project.
“Being away from them is hard, and knowing that they have to bring in coal every day,” said Charley. “When I do it, I know it’s laborious and chopping wood is a laborious task as well.”
With that, she decided to build a system to heat a traditional home. She used two solar technologies: heating with a solar collector and using a photovoltaic panel to power a pump that would circulate the antifreeze inside the system “so it would be heated.”
“I was able to heat the water inside the home to 21.4 Celsius (70.5 Fahrenheit),” said Charley. “This project was built around the idea that I would someday create something my grandparents would use inside their own home.”
This labor of love won her first place in the engineering category and third overall at this year’s Navajo Nation Science Fair held at Red Rock State Park last week.
