About This Reader

This engaging 250-word reading passage introduces fourth-grade students to the three layers of skin and their functions. Aligned with NGSS 4-LS1-1 and the Disciplinary Core Idea LS1.A, students learn that skin is the body's largest organ with distinct layers: the tough, waterproof epidermis on the outside; the dermis containing nerves, blood vessels, and sweat glands in the middle; and the subcutaneous fat layer that provides insulation and cushioning at the bottom. The passage uses simple, age-appropriate language and real-world examples to help students understand how each skin layer protects and supports the body. Audio-integrated features support diverse learners. Activities include multiple-choice comprehension questions, writing prompts that ask students to explain and apply concepts, and graphic organizers including a Structure and Function Table and a Layers Sequence Table. The Spanish translation and simplified differentiated version ensure accessibility for all learners. This resource builds foundational understanding of human body structures and prepares students for hands-on investigations about how organisms' internal and external structures support survival, growth, behavior, and reproduction.
