DE Science Elementary “5-Minute Prep” For Sound, Heat, and Light Light Color
Color – The Big Ideas Color is visible light of different wavelengths. A colored object reflects that color’s light waves and absorbs all others. A white object reflects all visible wavelengths. A black object absorbs all visible wavelengths. White light can be separated into light of different colors using a transparent prism. Ultraviolet and infrared light waves cannot be seen.
Color – Prior Knowledge Students have observed numerous colors in the world around them. They can use the FUN-damental, Sound, Heat, and Light, to review light. It will also be helpful if students have:Sound, Heat, and Light –used a large box of crayons or markers to create a colorful picture. –observed a natural rainbow.
Color – Common Misconceptions Colors appearing on soap films and oil slicks are reflections of rainbows. –Reality: The colors of soap bubbles and also oil slicks are due to thin-film interference. Just before a soap film breaks it stops showing color because it becomes too thin to produce interference. The primary colors for mixing colored lights are red, blue, and yellow. –Reality: The primary colors of light are red, blue, and green. It is very important to understand that mixing pigment and mixing light are not the same.
