About This Reader

This engaging 250-word reading passage introduces fourth-grade students to the internal structure and function of plant stems, aligned with NGSS standard 4-LS1-1 and the LS1.A Disciplinary Core Idea. Students discover that stems are not simply supports but complex transport systems containing specialized tubes that move water from roots to leaves and food from leaves throughout the plant. The passage uses the familiar celery stalk demonstration with colored water to make abstract concepts concrete and observable. Written at a Grade 4 reading level, the content includes age-appropriate vocabulary with clear definitions, relatable analogies comparing stem tubes to drinking straws, and real-world connections. The passage is audio-integrated to support diverse learners and includes a simplified differentiated version for students reading below grade level. Both English and Spanish translations are provided to support multilingual classrooms. Accompanying activities include multiple-choice comprehension questions testing recall and application, writing prompts requiring explanatory responses, and graphic organizers for visualizing structure-function relationships. This comprehensive resource builds foundational understanding of plant structures and their functions, preparing students for hands-on investigations and deeper exploration of how organisms meet their basic needs for survival.
