The document outlines the content and topics covered in a senior biology class at Colegio Las Cumbres for the school year. The content is divided into three terms. The first term covers variation and adaptation, plant adaptations, natural selection, and lab work on temperature graphs, feathers, and insulation materials. The second term covers the digestive, circulatory, excretory, and circulatory systems, including labs on teeth, vitamin C testing, and air samples. The third term focuses on releasing waste and energy as well as evolution.
