About This Reader

This engaging 250-word reading passage introduces fourth-grade students to the concept of sound communication aligned with NGSS standard 4-PS4-3. Students explore how sound waves are used to communicate in everyday life through relatable examples including talking, telephones, car horns, and fire alarms. The passage explains that sound is a form of energy that travels through air as vibrations, carrying information from one place to another over short and moderate distances. Students learn how vocal cords create sound waves when people talk, how phones convert sound into electrical signals and back again, and how warning sounds like horns and alarms alert people to important information. The content builds foundational understanding of sound energy and wave properties without requiring prior physics knowledge. Audio-integrated features support diverse learners. Accompanying activities include reading comprehension questions testing recall and application, writing prompts requiring students to explain concepts and make real-world connections, and graphic organizers helping students analyze cause-and-effect relationships and compare different communication methods. A simplified differentiated version ensures accessibility for all reading levels. Spanish translations of both passages support English language learners. This standards-aligned resource prepares students for hands-on sound investigations while developing scientific vocabulary and critical thinking skills essential for elementary physical science education.
