What Happened and Why

Aligned to RI.4.3 — Common Core State Standards for English Language Arts.

What this lesson teaches

History and science texts don't just tell what happened — they tell why. Look for the reasons and causes behind events, steps, or ideas. Words like 'because,' 'so,' and 'as a result' often point to the why.

Worked example

A science text explains that a puddle disappears because the sun heats the water and turns it into vapor that floats into the air. That tells both what happened and the reason it happened.

Practice questions

  1. Describe something you learned in science and explain why it happens.
  2. Read about a real event and list the cause and the result.
  3. Explain the steps of how something is made and why each step matters.

Qué Pasó y Por Qué

Los textos de historia y ciencia no solo dicen qué pasó — dicen por qué. Busca las razones y causas detrás de los eventos, pasos o ideas. Palabras como 'porque,' 'así que' y 'como resultado' suelen señalar el porqué.

Ejemplo: Un texto de ciencia explica que un charco desaparece porque el sol calienta el agua y la convierte en vapor que flota en el aire. Eso dice tanto qué pasó como la razón por la que pasó.
