This document outlines the content and schedule for a senior biology class. It includes three main topics that will be covered over the three trimesters: 1) The organization of life and the organism, including cell structure and transport, 2) Nutrition and transport in humans, focusing on the digestive and circulatory systems, and 3) Maintenance of organisms, covering respiration and the urinary system. Each topic includes sub-topics and related lab work. The class aims to teach students about various biological concepts through both classroom instruction and hands-on laboratory activities.
