Why an Apple Floats in the Sink

Fill a sink with water. Put in a whole apple. Plop! The apple does not sink. It bobs on top.

Why does it float? Look inside an apple. It has a lot of tiny spaces. The spaces are full of air. Air is very light. It helps the apple stay on top of the water.

Now think of a grape. It has few air spaces. It sinks.

Apples float, so some farms use water at harvest time. The water helps move the apples. A bobbing apple is easy to catch.

Imagine filling a kitchen sink with water and dropping in a whole apple. Plop! Instead of sinking, the apple bobs along on the surface.

Why does it float? If you could look inside an apple, you would find lots of tiny spaces. Those spaces are filled with air, and air is very light, so it helps the apple stay on top of the water.

A grape is different. It has only a few air spaces inside, so it sinks right down.

Because apples float, some farms use water at harvest time. The water helps carry the apples along, and a bobbing apple is easy to catch.

Ideas for class

  • Before reading, put float, sink, bob and tiny 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.
