Cause and Effect

A cause is why something happens. An effect is what happens as a result. For example, if you leave ice cream in the sun, it melts. The sun is the cause, and the melting is the effect. Understanding cause and effect helps you make sense of stories and real life.

Finding Cause and Effect

Look for signal words like because, so, since, and as a result. These words connect causes to their effects. Ask yourself why did this happen and what happened because of it. Sometimes one cause can have many effects, and one effect can have many causes.

Why It Matters

Understanding cause and effect helps you in many ways. In reading, it helps you follow the story. In science, it helps you understand how things work. In everyday life, it helps you make good decisions by thinking about what might happen next.
