About This Reader
This engaging 250-word reading passage introduces fourth-grade students to the essential internal structures that keep animals alive, aligned with NGSS standard 4-LS1-1 and Disciplinary Core Idea LS1.A. Students explore how the skeleton provides support and protection, the heart pumps blood throughout the body, lungs or gills obtain oxygen, the stomach and intestines digest food for energy, and the brain controls all body functions. The passage emphasizes that these internal structures are essential for survival and that different animals have different versions of these structures depending on their needs and environment. Audio-integrated features support diverse learners, while age-appropriate language and concrete examples make complex biological concepts accessible to fourth graders. The passage includes bolded vocabulary terms with immediate definitions, helping students build scientific literacy. Differentiated versions ensure all students can access the same core science concepts. Companion activities include comprehension questions, writing prompts, and graphic organizers that reinforce understanding of structure-function relationships in living organisms.
