About this reader
This engaging 250-word reading passage introduces fourth-grade students to the concept of exoskeletons, aligning with NGSS standard 4-LS1-1 and the Disciplinary Core Idea LS1.A: Structure and Function. Students discover that some animals like insects, crabs, and spiders have their skeleton on the outside of their body instead of inside. The passage explains how exoskeletons are hard outer coverings that protect soft body parts, provide support, and prevent water loss. Unlike internal skeletons with bones that grow continuously, exoskeletons cannot grow with the animal. This leads to the fascinating process of molting, where animals must shed their old exoskeleton and grow a new, larger one. The passage compares exoskeletons to internal skeletons, helping students understand the diversity of animal structures. Audio integration supports diverse learners by providing multiple ways to access the content. The simplified differentiated version uses shorter sentences and familiar vocabulary while maintaining the same core science concepts. Both English and Spanish translations are included to support multilingual learners. Accompanying activities include comprehension questions, writing prompts, and graphic organizers that reinforce understanding of structure and function relationships in living organisms.
