About this reader
This 250-word reading passage introduces fourth-grade students to the essential functions of blood in the human body, aligned with NGSS 4-LS1-1 and the Disciplinary Core Idea LS1.A: Structure and Function. Students learn how blood serves as both a delivery and cleanup system, transporting oxygen from the lungs to cells throughout the body, carrying nutrients from digested food to provide energy, removing waste products, and helping fight germs that cause illness. The passage uses age-appropriate language and relatable examples to build foundational understanding of how internal body structures support survival, growth, and behavior. Audio-integrated features support diverse learners, while the simplified differentiated version ensures accessibility for students reading below grade level. The passage includes bolded key vocabulary terms with immediate definitions, helping students develop scientific literacy. Supplementary activities include comprehension questions, writing prompts, and graphic organizers that reinforce understanding of blood's multiple functions. This resource prepares students for hands-on investigations and class discussions about body systems, providing the background knowledge necessary for deeper exploration of how organisms' internal and external structures function to support life processes.
