why is the sky blue science fair project
On a clear day, you can see that the color of the sky is blue even though sun light does not seem to contain any color. So
why is the sky blue if sunlight is colorless? The colorless light from the sun is actuallyPwhite light. It is made up of all the rainbow colors red, orange, yellow, green, blue, indigo, violet mixed together. Light bends when it passes from one medium (e. g. air) into another medium of a different densityP(e. g. water). This bending of light is called. Different colors areP by different angles because they have different wavelengths. As a result, when white light is refracted, it is separated into different colors, known asP. A rainbow is an excellent demonstration of the dispersion of light. After or during rainfall, you can see aP if the sunlight hits the water droplets in the air at the right angle. Another way to see the spectrum of colors that comprise the white light is by placingPa glass prism under strong sunlight.
In the air, there are many tiny air molecules. These moleculesPare very small, so small that we cant normally see them with our bare eyes even though the air is full of them, billions and trillions. On a clear day, sunlight passing through the atmosphere is scattered by air molecules. This scattering effect is called. Scattering is stronger with shorter wavelengths. Among visible colors, the blue-violet end of the color spectrum has the shortest wavelengths. So the blue-violet colors are scattered more than the red-orange colors. Although violet is scattered more than blue because its wavelength is shorter, are Pthan to violet. This is why the sky is blue during the day. To summarize, the sky is blue because the blue color inside the sunlight is scattered morePby air molecules and is perceived better by our eyes.
Why Is The Sky Blue? Experiment For Kids Here is a science experimentPthatPsimulates how sunlight passing through the atmosphere can turn the sky blue. We will use a flash light to turn a glass of white colloid into blue. Check out the video below to see how cool it is! Have you ever wondered why the sky looks blue? P In this Why is the Sky Blue science experiment, little learners can see for themselves how the blue wavelength is scattered faster than the red light from the sun. P The simple experiment needs only a few things, but it can be a fascinating launch pad for discussions about the sky, the sun, the solar system, and even the weather. P In fact, we will be featuring this experiment in our class! Why is the Sky Blue? Science Experiment Thought Question: Why is the sky blue? Materials: Directions: Put on your safety goggles and place a paper towel down on your work area in case the water spills.
Fill the empty glass halfway with water from the measuring cup. Add one tablespoon of milk to the water in the glass. Stir. Shine the flashlight through the milky water* and watch as the water begins to turn blue. *You may need to shine the flashlight up from the bottom of the glass to get the best results. Conclusion: The sky looks blue, because the blue wavelength scatters faster than the other wavelengths in the atmosphere. At sunset, we see the red and orange sky, because the blue has already been scattered out throughout the day.
