AP Biology

AP Biology Course Content

The course is based on four Big Ideas, which encompass core scientific principles, theories, and processes that cut across traditional boundaries and provide a broad way of thinking about living organisms and biological systems. The following are Big Ideas:

  • The process of evolution explains the diversity and unity of life.
  • Biological systems utilize free energy and molecular building blocks to grow, to reproduce, and to maintain dynamic homeostasis.
  • Living systems store, retrieve, transmit, and respond to information essential to life processes.
  • Biological systems interact, and these systems and their interactions possess complex properties.
Science Practices

Students establish lines of evidence and use them to develop and refine testable explanations and predictions of natural phenomena. Focusing on these disciplinary practices enables teachers to use the principles of scientific inquiry to promote a more engaging and rigorous experience for AP Biology students. Such practices require that students:

  • Use representations and models to communicate scientific phenomena and solve scientific problems;
  • Use mathematics appropriately;
  • Engage in scientific questioning to extend thinking or to guide investigations within the context of the AP course;
  • Plan and implement data collection strategies in relation to a particular scientific question;
  • Perform data analysis and evaluation of evidence;
  • Work with scientific explanations and theories; and
  • Connect and relate knowledge across various scales, concepts, and representations in and across domains.

AP Biology Students should have successfully completed high school courses in biology and chemistry.

AP Biology Exam : 3 HOURS

Assessment Overview

Exam questions are based on learning objectives, which combine science practices with specific content. Students learn to

  • Solve problems mathematically — including symbolically
  • Design and describe experiments and analyze data and sources of error
  • Explain, reason, or justify answers with emphasis on deeper, conceptual understanding.
  • Interpret and develop conceptual models.
  • Due to the increased emphasis on quantitative skills and application of mathematical methods in the questions, students are allowed to use simple four-function calculators (with square root) on the entire exam. Students also receive a formula list as part of their testing materials.
