The document outlines the content plan for a senior biology class. It includes three main content areas to be covered over the school year: 1) The organization of life and the organism, including cell structure and transport, to be covered in the first trimester. 2) Nutrition in humans, including enzymes, nutrients, and the digestive system, to be covered in the second trimester. 3) Maintenance of organisms, including the circulatory, respiratory and gas exchange systems, to be covered in the third trimester. Labs are included to complement each content area.
