About This Reader

This engaging science passage for Grade 4-5 students explores animal internal structure and how organs work together to keep animals alive and healthy. Students learn about the circulatory system with the heart pumping blood, the respiratory system with lungs breathing air, the digestive system with the stomach breaking down food, and the nervous system with the brain controlling the body. The passage connects these concepts to students' own internal organs, helping them understand the hidden structures that keep them alive. Audio-integrated content supports diverse learners. Aligned with NGSS science standards 4-LS1-1, this passage includes vocabulary support, Spanish translation, differentiated text, comprehension questions, writing activities, and graphic organizers to help students describe how internal structures perform functions essential for animal survival.
