One sunny morning, Sasha the Scientist looked up at the sky. "Why is the sky blue?" she wondered.

Sasha loved to find answers. So, she put on her scientist hat and started to investigate.

First, she read her science books. "Light from the sun is made of many colors," she learned.

Sasha found a prism in her science kit. She held it up to the sunlight.

The prism worked like magic! It spread the sunlight into a rainbow of colors.

"There are so many colors!" Sasha exclaimed. Red, orange, yellow, green, blue, indigo, and violet.

"Look at the blue light!" Sasha said. It was bouncing around more than the others.

Sasha went outside with her magnifying glass. She looked closely at the air.

"There are tiny things we can't see!" Sasha explained. They are called molecules.

These air molecules love to scatter blue light from the sun.

Sasha smiled. "That's why the sky looks blue!" she shouted.

She drew a big picture showing sunlight, the prism, and the blue sky.

Sasha shared her discovery with her friends. "The sky is blue because of sunlight and tiny air molecules!" she told them.

Now, whenever Sasha's friends look up, they remember her fun science lesson.

And Sasha felt happy. Solving mysteries was the best part of being a scientist!
