About this reader

This engaging 250-word reading passage introduces fourth-grade students to the concept of how organ systems work together in the human body. Aligned with NGSS standard 4-LS1-1 and the Disciplinary Core Idea LS1.A, the passage explains that body systems do not work independently. Students discover how the lungs bring in oxygen while blood carries it throughout the body, how the stomach breaks down food while blood delivers nutrients to cells, and how multiple systems coordinate during activities like running. The passage uses simple, age-appropriate language and real-world examples to build foundational understanding. Audio integration supports diverse learners by providing multiple ways to access the content. The passage includes bolded key vocabulary terms with immediate definitions, helping students build science literacy. Students explore the interconnected nature of the respiratory, circulatory, digestive, and muscular systems through concrete examples they can relate to their own experiences. This resource prepares students for hands-on investigations and classroom discussions about human body systems and their functions.
