About this reader

This comprehensive Grade 4 physical science reading passage explores how heat is produced through collisions and friction, aligned with NGSS standard 4-PS3-3 and Disciplinary Core Ideas PS3.A and PS3.B. Students discover that when objects rub together or collide, some of their motion energy transforms into heat energy. Through relatable examples like rubbing hands together, sliding on carpet, and using brakes, fourth graders build foundational understanding of energy transformation. The passage uses age-appropriate language and concrete analogies to explain friction and thermal energy. Audio-integrated materials support diverse learners. Complete with a simplified differentiated version, Spanish translations, glossary, multiple-choice quiz, writing activities, and graphic organizers, this resource provides multiple entry points for understanding how collisions produce heat. Perfect for introducing energy concepts before hands-on investigations and preparing students for deeper exploration of energy transfer in physical science.

Friction is a force that happens when two surfaces rub against each other. When objects collide or rub together, they create heat. You can test this yourself by rubbing your hands together quickly. After a few seconds, your hands feel warm. This warmth is heat energy created by friction.

When surfaces touch and move against each other, tiny bumps on each surface catch and drag. This rubbing slows down the motion, and some of the energy from the movement changes into heat. Energy is the ability to do work or cause change. Think of it like this: when you slide across a carpet in your socks, the rubbing between your socks and the carpet creates warmth on your feet.

Collisions are when objects bump into each other with force. During a collision, objects can also produce heat. When a car uses its brakes to stop, the brake pads press against the wheels. This creates friction and heat. Sometimes the brakes get so hot you can smell them!

Understanding how collisions and friction create heat helps us in everyday life. Thermal energy is another name for heat energy. It moves from warmer objects to cooler ones. Engineers design brakes, tires, and even running shoes with materials that handle friction safely. When you rub two sticks together to start a fire, you are using friction to create enough heat to make flames. The motion energy from rubbing transforms into thermal energy.

What is friction?

A force when surfaces rub togetherA type of cold energyThe speed of moving objectsA kind of collision only

What happens when you rub hands together?

They become cold and wetThey create heat from frictionThey lose all their energyThey stop moving completely

What creates heat in car brakes?

The engine running hotAir moving past the carBrake pads pressing on wheelsGasoline burning in the tank

Why does sliding on carpet make warmth?

The carpet has electricity in itRubbing surfaces create friction and heatYour socks are naturally very hotThe carpet absorbs cold from feet

How do engineers use friction knowledge?

To make objects never touchTo remove all heat from machinesTo design safe brakes and shoesTo stop all motion completely

What happens to motion energy during friction?

It disappears into space foreverIt transforms into thermal energyIt becomes sound energy onlyIt creates more motion energy

Thermal energy always moves from hot to cold.

TrueFalse

What does energy mean in science?

The ability to do workThe speed of lightThe weight of objectsThe color of materials
