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. . 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.
Experiment :Provide every group with a shallow container of milk. Place a couple of drops of different food coloring in the milk. Next, have a child dip a toothpick into a little dish soap and then dip it into the milk. What happens?
The children remembered the rainbow experiment and the colors that are needed to make secondary colors.
We lined up seven glasses of the same size next to each other . Gradually we added water to each jar from a small amount in the first one to the last one close to the rim.
Then w e added a bit of food coloring showing children how mixing the primary colors will yield the secondary color
Children received spoons and tapped the glasses to hear the different sounds that are produced. The glasses with more water will produce a lower pitch, and those with less water will produce a higher pitch sound .
