Tlw learn the colors of the rainbow, and observe a rainbow. Some people believed that a rainbow was a bridge that appeared in the sky when the gods wanted to leave heaven and come to earth. Some believed that if you find the end of the rainbow where it touches the earth you will find a pot of gold. A rainbow is caused by sunlight shining on raindrops. To see a rainbow, you must have the sun behind you and rain falling in front of you.
Sunlight looks white, but it is really made up of many colors.
When sunlight enters a raindrop, it divides into various color spectrums. The rainbow reflects these colors, like a mirror. Many rays of sunlight, breaking up into their colors and reflecting off many drops of falling rain, make a shimmering, curved, colored rainbow. As the glass is tilted left and right spots of color appear. Let the children name the colors observed.
