Hey there, curious minds! Welcome to Fizz Pop Wow, the super fun Science Podcast where we answer big questions with quick and exciting answers in less than five minutes. I'm Michelle, and today's question is full of color. How does a rainbow form? Let's find out!
The Science of Rainbows
Have you ever seen a rainbow after it rains? It appears in the sky like magic, shining in red, orange, yellow, green, blue, and purple! But where do rainbows come from? Is there a hidden treasure at the end? Are they painted in the sky? It’s not magic—it’s science! Rainbows happen because of sunlight and water. Even though sunlight looks white, it’s actually made up of all the colors of the rainbow. When sunlight passes through a raindrop, something amazing happens. It bends and spreads out into different colors. This is called refraction—it's how light changes direction when it moves through water.

Materials Needed:
- A clear glass of water
- A sunny window
- A white piece of paper
Steps to Follow:
- Fill a clear glass with water and place it near a sunny window.
- Hold a white piece of paper on the other side of the glass.
- What do you see? It's a rainbow!
- This happens because the water bends the sunlight, just like raindrops in the sky.
Why Are Rainbows Curved?
Rainbows aren’t actually straight—they’re curved! That’s because each tiny raindrop bends the sunlight at just the right angle to create a circle of color. But from the ground, we usually only see part of it, so it looks like an arch.

Key Takeaways
- Rainbows form when sunlight bends through raindrops.
- The bending of light is called refraction.
- Each raindrop helps create the rainbow’s curve.
