Why Sleds Slide and Sandpaper Grips

Rub your hands together fast. They get warm, and you can feel them pushing against each other. That push is called friction.

Friction is a force that happens when two things rub. It makes it harder for things to slide. It also makes them slow down.

Rough things have a lot of friction. Think of sandpaper. It is bumpy, so it grips anything that touches it. Boots with bumpy bottoms grip the ground, so you do not slip.

Smooth things have less friction. A sled slides well on slick snow or ice. Socks on a shiny floor can slide too. This is fun on a sled, but it is not safe when you walk on ice.

Friction can help us, and it can be in our way.

Rub your hands together briskly. They grow warm, and you can feel them pushing against each other. That resistance is called friction.

Friction is a force that appears whenever two surfaces rub. It makes sliding more difficult, and it causes moving things to slow down.

Rough surfaces create a great deal of friction. Sandpaper, for example, is bumpy, so it grips anything that touches it. Boots with bumpy soles grip the ground firmly, which keeps you from slipping.

Smooth surfaces create much less friction. A sled glides easily across slick snow or ice, and socks can slide across a shiny floor. That is wonderful on a sled, but it is not safe when you are walking on ice.

Friction can help us, and it can also get in our way.

How to use it

  1. Press Read it big (or B) to put the text on the projector, or Full screen (F) to fill the whole screen.
  2. Ask the questions one at a time and use Show answer when the class has decided. A shows or hides every answer.
  3. Print student copy for the class, or Print with answers for yourself.

Ideas for class

  • Before reading, put friction, force, grips and slick 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.
