3rd grade nonfiction hanging mobiles 160 words

A Mobile Is a Balancing Act

A mobile is a piece of art that hangs from the ceiling and moves in the air. Some mobiles have paper birds. Some have shiny shapes or small shells. All of them have to balance.

A mobile is built from bars. Each bar hangs from a string tied at one spot. A shape hangs from each end of the bar. If one shape is heavier than the other, the bar tips down on that side.

To fix this, the maker slides the string toward the heavy side. A heavy shape near the string and a light shape far from it can balance. It works the same way a see saw does when a small child sits far from the middle and a bigger child sits close.

Small bars can hang from bigger bars. The maker adds one at a time and checks the balance. When all the parts are just right, a soft breeze makes the whole mobile turn slowly.

A mobile is art that hangs from the ceiling. It moves in the air. Some mobiles have paper birds. Some have shiny shapes. All of them must balance.

A mobile is made of bars. Each bar hangs from a string. A shape hangs from each end. If one shape is heavier, the bar tips down on that side.

The maker slides the string toward the heavy side. Then the bar can balance. It is like a see saw. A big child sits close to the middle. A small child sits far from it.

The maker adds one bar at a time and checks it. Then a soft breeze can turn the whole mobile.

A mobile is a piece of art that dangles from the ceiling and drifts with the movement of the air. Some mobiles carry paper birds, while others hold glittering shapes or tiny shells. Whatever they carry, every mobile must be balanced.

A mobile is constructed from bars. Each bar hangs from a string that is tied at a single spot, and a shape dangles from each end of the bar. When one shape is heavier than the other, the bar tips down toward the heavy side.

To correct this, the maker slides the string closer to the heavy side. A heavy shape near the string can balance a light shape far from it. A see saw works the same way when a small child sits far from the middle and a bigger child sits close to it.

Smaller bars can hang from larger bars. The maker adds them one at a time, checking the balance each time. Once every part is just right, a gentle breeze will turn the entire mobile slowly.

Ideas for class

  • Before reading, put mobile, balance, heavier, breeze and ceiling 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 2 minutes 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.
