The Rainbow Maker

A girl experiments with light and water in her garden and discovers the science behind rainbows.
Moral: Curiosity and experimentation are the tools of science. The best discoveries come from asking "what if I try this?"
Priya wanted to make a rainbow. Not find one, not wait for one. Make one herself. She had seen them after rain, always in the sky, always where the sun hit water in the air. She had a theory. She went to the garden with the hose. She turned her back to the sun, the way her dad had once told her: "The sun has to be behind you to see a rainbow." She turned the hose to its finest spray setting and sent a mist of water into the air in front of her. There. A small rainbow curved through the mist. "It works!" Priya ran inside to get her notebook. She wrote: Rainbows happen when sunlight goes through water droplets. The water bends the light and splits it into colors. The colors are always the same order: red, orange, yellow, green, blue, indigo, violet. She tried to memorize the order. Her dad taught her a name: Roy G Biv. Each letter was the first letter of a color. She spent the whole afternoon making rainbows of different sizes, moving closer and further from the spray. She found that she always had to be in exactly the right position: sun behind her, water in front. "You discovered the geometry of rainbows," her dad said. Priya looked at her notes. "Mostly I just like that I can make them whenever I want now," she said. That seemed like the best kind of learning to her.
