What is a Rainbow? Simple Explanation for 4-Year-Old Children

Hello! Let's learn about rainbows. A rainbow is a beautiful, colorful arch you see in the sky. It happens when the sun shines while it is raining or just after the rain stops.

Here’s how it works: Raindrops are like tiny glass balls holding water. When sunlight goes into these raindrops, it splits into many colors, like red, orange, yellow, green, blue, and purple. These colors come out of the raindrop and make a pretty rainbow in the sky.

So, a rainbow is a special light show in the sky made by sunlight and rain working together. Next time you see one, you’ll know why it’s there!
