About this reader
This 250-word reading passage introduces fourth-grade students to how animal lungs work, aligned with NGSS standard 4-LS1-1 and Disciplinary Core Ideas LS1.A. Students learn that lungs are internal organs that take in oxygen from the air and release carbon dioxide. The passage explains the breathing process: when animals breathe in, air fills the lungs and oxygen passes into the blood; when they breathe out, carbon dioxide leaves the body. Students discover why animals need oxygen—to turn food into energy—and learn that different animals have different-sized lungs depending on their body size and activity level. The passage uses simple, age-appropriate language and includes relatable examples to help students understand this essential life process. Audio integration supports diverse learners by providing text-to-speech functionality. Accompanying activities include multiple-choice questions testing recall and comprehension, writing prompts requiring explanation and application, and graphic organizers for visualizing the breathing process and comparing lung structures. The passage is also available in a simplified differentiated version and Spanish translation to support all learners. This resource builds foundational understanding of respiratory systems, preparing students for hands-on investigations and deeper exploration of how organisms obtain and use energy.
