Forces and Motion — Reading Passage

Physical Science Grade 3-5 NGSS 3-PS2-1 Reading Passage

About this worksheet

This reading passage printable supports 3-5 learners working on Forces and Motion. A 2-3 paragraph nonfiction reading followed by 10 comprehension questions — main idea, vocabulary in context, cause/effect, and short-response prompts. Use it as guided practice during your unit, as a take-home review, or as a quick formative check before moving on to the next concept. The activity is aligned to NGSS performance expectation 3-PS2-1 and pairs cleanly with hands-on demonstrations, picture books, and short videos already in your classroom rotation. An answer key with teacher notes appears at the bottom of this page so you can grade in seconds and identify common misconceptions before they harden.

Learning objectives

  • Define force, motion, and friction.
  • Predict how a bigger force changes motion.
  • Identify everyday examples of friction and gravity.
  • Design a fair test of force and motion.

Vocabulary

force
A push or a pull.
motion
A change in position over time.
speed
How fast something moves.
friction
A force that slows objects down.
gravity
A force that pulls objects toward Earth.

Practice exercises (10 questions)

Print this section for students. Reveal the answer key below for grading.

  1. In your own words, a force is a push or a pull.
  2. State the learning objective for Forces and Motion in your own words.
  3. Give one real-world example that shows friction is a force that slows objects down.
  4. Why is it important for a scientist to know that a force is a push or a pull?
  5. How would you explain to a younger student that bigger forces produce bigger changes in motion?
  6. Draw a quick sketch that shows friction is a force that slows objects down. Label two parts.
  7. Compare a force is a push or a pull with one other idea you have learned in this unit.
  8. Which everyday observation would best support the idea that bigger forces produce bigger changes in motion?
  9. Predict what would happen if friction is a force that slows objects down were not true.
  10. Write one new question you still have about a force is a push or a pull.

  1. A force is a push or a pull.
  2. Define force, motion, and friction.
  3. Example: Friction is a force that slows objects down.
  4. Because A force is a push or a pull.
  5. You could say: Bigger forces produce bigger changes in motion.
  6. A correct sketch shows Friction is a force that slows objects down. and labels two clear parts.
  7. A complete answer notes that A force is a push or a pull., then names a second idea and one similarity or difference.
  8. Any observation that points back to: Bigger forces produce bigger changes in motion.
  9. A reasonable prediction explains a consequence of removing the fact that Friction is a force that slows objects down.
  10. Accept any thoughtful question about A force is a push or a pull.; look for evidence the student is connecting to today's big idea.

Teacher notes

Watch for these common misconceptions: A force is a push or a pull. Many students will guess based on appearance instead of evidence — encourage them to point to a specific clue from the passage or diagram. For early finishers, ask them to draw their own example or write a one-sentence summary on the back of the page.

How to use in class

Print one copy per student, or project the page on your board for a whole-class discussion. The reading passage format works well as a 10-15 minute activity within a 45-minute science block. Younger students may need the directions read aloud the first time you use this format; once they have done one or two, they can usually start independently. For early finishers, ask them to flip the page over and either draw an example from real life or write one new question they still wonder about. Both options stretch their thinking without requiring extra prep from you.

If you are teaching this unit in a multi-grade classroom or a homeschool setting with siblings of different ages, scaffold by reading the first two questions aloud with the whole group, then release younger students to work in pairs while older students complete the printable independently. The reveal-on-click answer key keeps the page free of distractions while students are working.
