Ap® biology (intensive, ncaa approved).

• Advanced CTY-Level
• Session-Based
• Science and Engineering

Advance your understanding of high school biology concepts as you cover topics typically found in a first-year university biology course. This course includes a laboratory component designed to meet College Board® standards and provides a solid foundation for the AP Biology exam, which you’ll prepare for using online lectures, readings, laboratory exercises, homework assignments, and exams that mirror the AP format. Major themes include biochemistry, energy transfer, cellular structure and specialization, mitosis and meiosis, genetics, and ecology, among others. 

This course does not have any synchronous class meetings, but you can schedule one-on-one virtual meetings directly with your instructor to answer questions.

Time Commitment: 12-16 hours per week (1-hour optional meeting, 12-15 hours of independent work).  

Course Overview

What we'll do

We’ll use virtual interactives, short videos, an online textbook, hands-on labs completed from a lab kit, discussion boards with other students, and quizzes/tests. Your instructor will provide detailed feedback on written assignments.

What we’ll learn

• That evolution is a change in the genetic makeup of a population over time, with natural selection as its major driving mechanism
• The ways biological systems interact from the molecular level to the ecosystem level; how they use energy and molecular building blocks to grow, reproduce, and maintain dynamic homeostasis
• How organisms respond to changes in their environment at the molecular, cellular, physiological, and behavioral levels
• The ways that living systems store, retrieve, transmit, and respond to information essential to life processes, and how genetic information provides for continuity of life, and, in most cases, is passed from parent to offspring via DNA

By the end of this course, you will be able to:

• Use written explanation, models, and visual representations to justify scientific arguments based on analysis of organisms’ struggle to survive in relation to natural selection, environmental changes, and human-induced events on the evolution of organisms, populations, and ecosystems
• Quantify chemical reactions that explain how energy is transformed, transferred, and stored to be used by organisms in response to their environment and to maintain homeostasis
• Model how energy deficiencies are detrimental to individual organisms, disrupt populations and ecosystems, and can cause distinct selective pressures
• Evaluate how information is stored, retrieved, and transmitted in living systems through heritable genetic information and nonheritable cellular communication, interdependent organism systems, and populations
• Analyze the biocomplexity and diversity of characteristics in biological systems from the molecular to the ecosystem level, expressing how this contributes to robust biological systems, greater resiliency, tolerance, and response to changes in the environment
• Demonstrate scientific biology practices in lab experiments that include determining scientific questions and methods, representing and describing data, performing statistical tests, and other mathematical calculations
• Demonstrate critical written scientific skills in lab reports that include visual representations of biological concepts, processes, and models, as well as analysis and interpretation of data to justify scientific arguments using evidence

How we'll measure learning

Students will be assessed during each unit using homework questions, discussions, hands-on laboratory experiments with written lab reports, and a unit test. There will be a midterm and final exam composed of past AP exam questions. All assignments are graded with rubrics and answer keys and detailed feedback is provided. This course is aligned to College Board standards for AP Biology as well as the Next Generation Science Standards for High School Life Science.

About Science and Engineering at CTY

Our Science and Engineering courses bring a variety of science topics to life. By introducing topics not covered in standard science curricula, we build and reinforce your science knowledge. All courses support critical thinking, problem solving, and reasoning, and encourage a real-life, hands-on approach to learning about Earth, space, life sciences, chemistry, and the physical world. Guided by expert CTY science educators, you’ll master science lab kits, perform hands-on experiments using common household objects, participate in dynamic group discussions, or prepare for AP exams.

Newly revised Honors Physics course

Our completely redesigned  Honors Physics course features new lessons, conceptual and problem-solving videos, and guiding questions that teach students how to solve each type of problem. Hands-on exploration activities challenge students to solve everyday physics problems from how giant cruise ships stay afloat to how to ship fragile packages without them breaking. Putting their physics knowledge to the test, students compete in our catapult design competition for Furthest Launch and Creative Design awards.

More engaging science enrichment courses!

In the newly revised  Inventions in Engineering  course, students bring fantasy into reality by creating inventions to solve the problems of favorite fictional characters and the real world alike. A new unit in Introduction to Forensics asks students to evaluate the validity of various kinds of forensic evidence and its impact on the lives of individuals, and to provide recommendations on which types of forensic evidence should be admissible in the criminal justice system. In Household Chemistry , students engage in newly revised activities that help develop their skills in making and recording detailed observations using all 5 senses as they explore states of matter and the role chemistry plays in their daily lives.

Meet our Science and Engineering Instructors

I try to teach less and make students think more so they can come up with their own answers coupled with a better, deeper understanding of the subject matter.

One of the joys of teaching science is encouraging students to observe closely the world around them. I enjoy when students start to think critically about how everything in the natural world interacts with everything else, and how they can apply what they have learned in class to real life.

Keith Gallinelli

Science and Engineering Instructor

I am amazed at the level of tenacity of my students and am inspired by their quest to learn beyond walls and defined standards. They inspire me to learn more about our dynamic scientific world for continuous growth of their eager minds.
