AP Biology (NCAA Approved)

Course Description

Description

The AP Biology course covers topics typically found in a first-year college biology course and advances the student's understanding of concepts normally covered in high school biology. It provides a solid preparation for the AP Biology exam, and draws on software provided by Thinkwell.

Major course themes include:

• biochemistry
• energy transfer
• cellular structure and specialization
• cellular metabolism
• mitosis and meiosis
• genetics
• ecology

Organismal diversity, from microorganisms to plants and animals and the continuity of life through genetics and development are emphasized. Highly qualified instructors guide students through online lectures, readings, animations, laboratory exercises, and other resources. Student knowledge is assessed through homework assignments and exams. This course includes a laboratory component designed to meet College Board standards and has been reviewed and approved by the College Board.
