About This Reader

This engaging 250-word reading passage introduces Grade 4 students to the structure and function of bones, aligned with NGSS standard 4-LS1-1 and Disciplinary Core Idea LS1.A. Students discover that bones are not dry and dead like they appear in pictures, but are actually living parts of the body with important jobs. The passage explains the hard outer layer that provides strength and protection, and the softer inside called bone marrow that produces blood cells. Students learn how bones grow as they grow and can even heal themselves when broken. The passage includes audio integration for accessibility, bold key vocabulary terms with immediate definitions, and relatable examples. Supplementary materials include a simplified differentiated version for struggling readers, Spanish translations of both passages, an 8-question multiple-choice quiz testing recall and comprehension, writing activities requiring application of concepts, and two graphic organizers (Structure and Function Table, Main Idea and Supporting Details Table) to help students organize their understanding. This comprehensive resource helps students build foundational understanding of bones as living, active structures essential for body support, protection, movement, and blood cell production.
