This document outlines a lesson plan for teaching students about the human body systems. It uses a K-W-L framework to structure what students already know (K), what they will learn (W), and what they will know by the end of the unit (L). According to the plan, students will learn about the nervous system, sense organs, musculoskeletal system, and importance of healthy habits. They will also practice scientific skills like gathering and analyzing data, and communicating findings orally and in writing. The goal is for students to understand the main body systems and functions, and recognize healthy versus unhealthy lifestyles.
