2nd grade nonfiction light bending in water 125 words

A Rainbow Made by a Glass of Water

Sunlight looks white or yellow. But it is really a mix of many colors. You can see the colors in a rainbow.

You can make colors yourself. Set a clear glass of water on a sunny windowsill. Light shines through the water, and the light bends. Each color bends by a different amount. So the colors spread apart. With luck, a band of colors shows up on the wall.

Raindrops do the same job. After a rain shower, the sun may shine through many drops. Each drop bends the light and splits it into colors. Together they make a rainbow in the sky.

A rainbow always has the same colors in the same order. Red is on the outside, and violet is on the inside.

Sunlight appears white or yellow, but it is really a blend of many different colors. You can see those colors spread out in a rainbow.

Sometimes you can create colors yourself. Set a clear glass of water on a sunny windowsill. Light shines through the water and bends, and each color bends by a slightly different amount, so the colors fan apart. With luck, a band of colors will appear on the wall or the floor.

Raindrops work in a similar way. After a rain shower, the sun may shine through millions of drops. Each drop bends the light and splits it into its colors, and together they form a rainbow across the sky.

A rainbow always shows the same colors in the same order. Red is on the outside, and violet is on the inside.

Ideas for class

  • Before reading, put sunlight, bends, windowsill and violet on the board with their meanings from the Words to know section and have students predict what the text will be about.
  • Read it aloud once while students follow along, then have them reread it alone or with a partner. At a calm 100 words a minute it takes about 1 minute to read aloud.
  • Use the Read it big button (or B) to put the text on the projector, and Show answer on one question at a time so the class commits to an answer first.
  • Question 5 asks the reader to infer. Ask students to point to the words in the passage that led them to their answer.
  • Ask students to write one question the passage did not answer, then look for the answer in a book or on a classroom screen.
  • Print the student copy for independent work and keep the answer-key copy for yourself.
