About this reader

This 250-word audio-integrated reading passage introduces fourth-grade students to the essential function of the heart as an internal organ. Aligned with NGSS 4-LS1-1 and the Disciplinary Core Idea LS1.A, the passage explains how the heart pumps blood throughout the body to deliver oxygen and nutrients to every cell while removing waste products. Students discover that the heart beats continuously to keep blood flowing and learn about heart diversity across the animal kingdom. The passage compares human four-chambered hearts with fish two-chambered hearts and insect tube-like hearts, helping students understand that different animals have different internal structures suited to their needs. Written at a Grade 4 reading level with age-appropriate vocabulary and clear explanations, this resource includes a simplified differentiated version, Spanish translations, glossary terms, multiple-choice questions, writing activities, and graphic organizers. The passage builds foundational understanding of circulatory systems without assuming prior science knowledge, preparing students for hands-on investigations and classroom discussions about how body systems support survival and growth.
