About This Reader

The Domino Chain Reaction passage is a dynamic and engaging educational resource designed for fourth-grade science students. The text aligns with the Next Generation Science Standards (NGSS) Disciplinary Core Concept PS3.B: Conservation of Energy and Energy Transfer, offering a clear and relatable example of this complex topic. Students will learn about potential and kinetic energy as they follow the journey of a domino chain reaction. The passage explains how pushing the first domino transfers kinetic energy from one to the next, and how some energy is converted into sound and heat along the way. The included assessment, featuring multiple-choice questions at varying DOK levels, helps teachers gauge student comprehension and critical thinking skills. This material is an excellent tool for hands-on learning and reinforces key scientific principles.

What Is a Domino Chain Reaction?

A chain reaction happens when one event starts a series of other events. In a domino chain reaction, a row of standing dominoes is set up close together. When you push the first domino, it falls and knocks into the next one. This keeps happening, and the energy moves down the line until every domino has fallen.

How Does Energy Move?

Before you touch the dominoes, each one has potential energy. This is stored energy because the domino is standing up and could fall. When you push the first domino, that potential energy turns into kinetic energy, which is energy of movement. As each domino falls, it hits the next one, passing on its energy. This is called energy transfer. Some energy also turns into sound and a tiny bit of heat.

Why Are Chain Reactions Special?

A domino chain reaction is special because a tiny push can make a huge change. It’s like the world’s longest game of tag—each domino "tags" the next one with energy until all have fallen! One small action can have a big result.

Design Challenges

Setting up dominoes isn’t always easy. If dominoes are too far apart, the chain reaction stops. If the surface is slippery, dominoes may slide instead of standing up. You can also make patterns, curves, or even tricks. Changing the spacing or adding obstacles can make the reaction more exciting or harder to complete.

Real-World Chain Reactions

Domino chain reactions help us understand other chain reactions, too. For example, a forest fire can start with one spark and quickly spread. Nuclear power plants use chain reactions to create energy. Even viral videos online spread from one person to many, like dominoes falling. That’s why we are careful with things like fire—one small action can cause a big reaction.

Hands-On Activity

Try making your own domino chain reaction. Experiment with different patterns, spacings, and obstacles. See how changing one thing can affect the whole reaction!

Interesting Fact: The world record for most dominoes toppled in a chain reaction is over 4 million!

What is a chain reaction?

One event causes another and so onOnly one thing happensThings happen randomlyDominoes never fall

What energy do standing dominoes have?

Potential energyKinetic energySound energyNo energy

What happens if dominoes are too far apart?

Chain reaction stopsThey fall fasterThey make more soundThey bounce up

What is energy transfer?

Energy moves to another objectEnergy disappearsEnergy gets colderEnergy stays in one place

Why are chain reactions important?

Small action causes big resultThey always stop quicklyThey use no energyThey never happen

How are domino chains like viral videos?
