Adults are not alone in playing important roles in science. Discover some impressive discoveries made by children.
Children, with their infinite curiosity and tendency to wander off limits, are also involved in scientific research and exploration.
From spotting a supernova to digging up dinosaur bones, here are seven amazing discoveries made by children.
During summer break, a child turned into an unexpected history lesson when he discovered a 10,000-year-old arrowhead in the sand of a New Jersey beach.
Noah Cordle, 10, discovered the rare artifact while playing on the brink of the surf, according to the Associated Press. His family contacted the New Jersey Archaeological Society for information about what the boy had found.
The society's president, Greg Lattanzi, told his family that the artifact was a stone arrowhead probably used by pre-tribal Native Americans, or Paleo-Indians, who passed through the area between 8,000 and 11,000 years ago, hunting fish and birds.
In November 2013, a 10-year-old child in Canada became the youngest person to discover a supernova. Nathan Gray spotted the supernova with a little help from his father and Dave Lane.
The young astronomer told CBC News that he had been observing the night sky for six months, hoping to observe a star burst. He said the supernova looked like a "flashing star" and that he was both "very excited and happy" to have made the discovery.
Need proof that high school science projects generate scientific breakthroughs? Meet Simon Kashchock-Marenda, a student in the US whose unique experience inspired a study by scientists at the University of Drexel in Philadelphia.
Kashchock-Marenda was interested in finding out how artificial sweeteners affect fruit flies. He fed groups of flies with different sweeteners, one of which was Truvia, an artificial sweetener containing a sugar alcohol called erythritol.
Truvia-fed flies died within six days, leading the fledgling scientist to hypothesize that for fruit flies Truvia is not a healthier alternative to sugar.
With the help of his father, a biology professor at Drexel, the high school student repeated the experiment under laboratory conditions and observed similar results. Drexel researchers later concluded that erythritol in Truvia has a toxic effect on flies.
In April 2014, a boy from Michigan discovered something really cool - a 10,000-year-old mastodon tooth. 9-year-old Phillip Stoll tripped over his tooth while walking barefoot in a creek near his home.
The tooth was brown, about eight inches long and had six distinct peaks. Despite its unusually large size, Stoll told CNN that he recognized the object as a tooth immediately.
He and his mother contacted James Harding, an amphibian and reptilian herpetologist at Michigan State University, to learn more about the origins of the strange-looking tooth.
For over a decade, people in Southern California have been getting sick (and in some cases have died) after contacting a fungus called Cryptococcus gattii. But for years, scientists who study C. gattii They were unable to determine exactly where people were found this deadly fungus.
Filler, a seventh grader looking for a legal science fair project, was encouraged by her father, an infectious disease expert, to find out where C. gattii It was hidden. Filler began investigating and finally identified at least three fungus-infected trees in the greater area of Los Angeles.
She shared her discovery with researchers at Duke University in North Carolina. Their findings were part of a study published August 21, 2014 in the journal PLoS Pathogens.
The newest duckbill dinosaur ever discovered was found by a boy. In 2009, Kevin Terris was conducting paleontology fieldwork for a high school class when he discovered some dinosaur baby bones under a rock.
With the help of paleontologist Andrew Farke, Terris and his colleagues dug up the remains of a Parasaurolophus, a Cretaceous herbivore that roamed the earth some 75 million years ago.
In 2008, 9-year-old Matthew Berger spent a day with his archaeologist father to an excavation near Johannesburg, South Africa, when he discovered what was later identified as the remains of one of the relatives of humanity the Australopithecus sediba.
The 2,000,000-year-old bones were located outside the area that the boy's father, Lee Berger, had delimited. Berger said his son found the remains after fleeing the site to explore on his own.
The researchers later concluded that the young explorer discovered bones belonging to a previously unknown ancient hominid. Berger's father and his team later unearthed two other skeletons from the site.
