2nd grade nonfiction heat and melting ice 123 words

Ice Cube Race: Sun Against Shade

Here is a race with no running. Two ice cubes will race to melt. Which one will win?

Put one ice cube on a plate in a sunny spot outside. Put the other ice cube on a matching plate in the shade. Make sure the two cubes are the same size. That makes the race fair.

Now wait and watch. The cube in the sun gets smaller fast. Its edges turn round and a puddle grows. The cube in the shade melts too, but slowly.

The sun gives off heat. Heat is a kind of energy that makes things warmer. Heat moves into the ice, and the ice turns into water. Sunny spots get more heat, so the sun cube wins the race.

Here is a race that requires no running at all. Two ice cubes will compete to see which one melts first. Which will win?

Place one ice cube on a plate in a sunny spot outdoors, and place the other on an identical plate in the shade. Be sure the two cubes are exactly the same size, so that the race is fair.

Now wait and watch carefully. The cube in the sun shrinks quickly, its edges turn round, and a puddle spreads beneath it. The cube in the shade melts as well, but much more slowly.

The sun gives off heat, a kind of energy that makes things warmer. Heat flows into the ice and turns it into water. Sunny spots receive more heat, so the cube in the sun wins the race.

Ideas for class

  • Before reading, put melt, shade, energy and puddle 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.
