Course Overview

Biology A is the first part of a two-course sequence that introduces students to the fundamental principles of biology. This course focuses on cell structure and function, genetics, and evolution, while also exploring the unity and diversity of life on Earth. Students examine living systems ranging from microorganisms to complex multicellular organisms, studying how life is both diverse in form and unified by shared biological processes. Emphasis is placed on understanding how scientific inquiry, experimentation, and analysis contribute to the development of biological knowledge.

Key Learning Focus

• Cell Biology: Investigating the structure, function, and composition of cells as the building blocks of life.
• Genetics: Exploring principles of heredity, DNA structure, genetic variation, and the application of Mendelian genetics.
• Evolution: Examining the mechanisms of evolution, natural selection, and the relationships among organisms through phylogenetic studies.
• Unity and Diversity of Life: Understanding the shared characteristics of living organisms while exploring their vast diversity.
• Scientific Inquiry: Developing problem-solving, critical thinking, and research skills through data analysis and hands-on experimentation.

Instructional Approach

Biology A emphasizes interactive and project-based learning. Students engage in laboratory experiments such as examining cells under microscopes, conducting genetic crosses, and modeling evolutionary patterns. Virtual simulations and inquiry-based activities complement hands-on work, reinforcing concepts and connecting theory to practice. The curriculum integrates real-world applications, career exploration, and collaborative projects to deepen understanding and relevance.

Academic Alignment and Progression

This course is aligned with the Next Generation Science Standards (NGSS) and state and national science education benchmarks. Biology A is designed for grades 9–12 and serves as a core science course that prepares students for Biology B, advanced biology electives, and AP Biology. Successful completion provides a strong foundation for future studies in life sciences, healthcare, environmental science, and related career pathways.

Outcomes

By the end of Biology A, students will:

• Demonstrate understanding of cell structure, function, and processes.
• Apply genetic principles to explain patterns of inheritance and variation.
• Analyze evolutionary evidence and explain mechanisms driving biodiversity.
• Conduct laboratory experiments and interpret scientific data effectively.
• Connect biological principles to real-world issues and career pathways in science.
