📖 Why Sound Cannot Travel in Space

Sound is a mechanical wave that requires particles to pass vibrations along. Air, water, and solids contain particles that can transmit sound. Most of space is close to a vacuum with extremely few particles. Without enough matter, ordinary sound waves cannot travel between spacecraft.

1. What key idea begins the explanation?

 

2. What mechanism or supporting detail is described?

 

3. What additional evidence or effect is given?

 

4. How does the final detail deepen the explanation?

 

✏️ Writing

Write 1–2 developed paragraphs explaining why sound cannot travel in space. Use evidence and cause-and-effect reasoning.

➕ Math

1. A school collects 12 boxes containing 23 books each. How many books are collected? ______
2. 52 books are donated to another school. How many remain? ______
3. Write an equation representing both steps: __________________
4. Explain how you know your answer is reasonable: __________________

🎨 Color & Create
