Ability to find and use available resources to achieve goals, problem-solve, and shape the future. Whether or not you have a budding ecologist, neuroscientist, or engineer, all children gain important abilities when parents support and encourage doing at-home, easy science experiments.

For kids of all ages, the benefits are enormous. It also nurtures intellectual curiosity , helping children acquire new ways of asking questions and understanding the world. Scientific exploration is a great summertime activity for families or just plain old-fashioned fun during the school year. When accomplished in a non-competitive home or after-school environment, children are free to discover new interests that often lead to fascinating hobbies or educational pursuits.

To get the most out of science experiments, kids need to choose the activity and be involved in planning, decision-making, and executing the experiment. If you are inclined to browse the Internet for just the right science experiments, stop!

Kids have more fun learning and learn more! Good mentors listen, ask questions, encourage, and support. As you begin to plan and evaluate science experiments, you may find the following guidelines useful:. The first and most important part of choosing a science experiment for kids is finding the right match between the project and the child. Have fun exploring them with your child!

He meticulously documented how matching yellow peas and green peas, for instance, always yielded a yellow plant. Yet mating these yellow offspring together produced a generation where a quarter of the peas gleamed green again.

He was ahead of his time. Experimental result: The nature of color and light. To escape a devastating outbreak of plague in his college town of Cambridge, Newton holed up at his boyhood home in the English countryside. Let sunlight pass through a prism and a rainbow, or spectrum, of colors splays out. Unconvinced, Newton set up a prism experiment that proved color is instead an inherent property of light itself. This revolutionary insight established the field of optics, fundamental to modern science and technology.

Newton deftly executed the delicate experiment: He bored a hole in a window shutter, allowing a single beam of sunlight to pass through two prisms. By blocking some of the resulting colors from reaching the second prism, Newton showed that different colors refracted, or bent, differently through a prism. The medium did not matter. Color was tied up, somehow, with light itself.

In making his name, Newton certainly displayed a flair for experimentation, occasionally delving into the self-as-subject variety. One time, he stared at the sun so long he nearly went blind. Another, he wormed a long, thick needle under his eyelid, pressing on the back of his eyeball to gauge how it affected his vision.

Experimental result: The way light moves. Ocean waves, too, move through their own medium: water. Light waves are a special case, however. In a vacuum, with all media such as air and water removed, light somehow still gets from here to there. How can that be? What followed is arguably the most famous failed experiment in history. When the path of a light beam travels in the same direction as the wind, the light should move a bit faster compared with sailing against the wind.

To measure the effect, miniscule though it would have to be, Michelson had just the thing. In the early s, he had invented a type of interferometer, an instrument that brings sources of light together to create an interference pattern, like when ripples on a pond intermingle.

A Michelson interferometer beams light through a one-way mirror. The light splits in two, and the resulting beams travel at right angles to each other. After some distance, they reflect off mirrors back toward a central meeting point. If the light beams arrive at different times, due to some sort of unequal displacement during their journeys say, from the ether wind , they create a distinctive interference pattern.

Neither researcher fully grasped the significance of their null result. Chalking it up to experimental error, they moved on to other projects. Fruitfully so: In , Michelson became the first American to win a Nobel Prize, for optical instrument-based investigations. Experimental result: Defining radioactivity. Few women are represented in the annals of legendary scientific experiments, reflecting their historical exclusion from the discipline.

Marie Sklodowska broke this mold. Born in in Warsaw, she immigrated to Paris at age 24 for the chance to further study math and physics. There, she met and married physicist Pierre Curie, a close intellectual partner who helped her revolutionary ideas gain a foothold within the male-dominated field. Ogilvie, professor emeritus in the history of science at the University of Oklahoma. The Curies worked together mostly out of a converted shed on the college campus where Pierre worked. For her doctoral thesis in , Marie began investigating a newfangled kind of radiation, similar to X-rays and discovered just a year earlier.

Using an instrument called an electrometer, built by Pierre and his brother, Marie measured the mysterious rays emitted by thorium and uranium. Instead, radioactivity — a term she coined — was an inherent property of individual atoms, emanating from their internal structure. Up until this point, scientists had thought atoms elementary, indivisible entities.

Marie had cracked the door open to understanding matter at a more fundamental, subatomic level. Curie was the first woman to win a Nobel Prize, in , and one of a very select few people to earn a second Nobel, in for her later discoveries of the elements radium and polonium. Experimental result: The discovery of conditioned reflexes.

Russian physiologist Ivan Pavlov scooped up a Nobel Prize in for his work with dogs, investigating how saliva and stomach juices digest food. While his scientific legacy will always be tied to doggie drool, it is the operations of the mind — canine, human and otherwise — for which Pavlov remains celebrated today. Gauging gastric secretions was no picnic.
