This document outlines a lesson plan on the parts of blood. It begins with objectives and materials, then describes the components of blood - plasma, red blood cells, white blood cells, and platelets. The procedure involves engaging students with questions and a song about blood, having them explore the components in a video and answer questions, and explaining what blood is and the function of its parts. Students will then apply what they learn by discussing what would happen without blood and evaluating their understanding.
