Core Natural Sciences Courses

Statistics

Students develop skills in the essential tools used for statistical analysis and decision making in business. The course covers descriptive and inferential statistics and emphasizes research techniques such as sampling and experimental design concepts for single- and multiple-sample groups.

Biology

An introduction to the study of life and life processes, this course covers topics including the scientific method, the chemistry and processes necessary for life, cells and cellular organization, energy production, and evolution and natural selection. Students also examine reproduction and the applications of biological principles to everyday experiences.

General Chemistry

General Chemistry examines topics including chemical nomenclature, measurement, states of matter, the atom, chemical bonding, solutions, stoichiometry, and thermochemistry, and how these apply in the world around us. The course introduces students to the structure of the atom and the basic physical laws that govern matter, as well as the processes chemists and scientists use to determine the composition and nature of matter.

Natural Sciences Capstone Course

This is a senior-level course for advanced students and working professionals, designed to help integrate their studies in the natural sciences. The course applies multiple theories and research approaches to current events from the perspective of a variety of disciplines, including geology, chemistry, physics, and biology. Students use their critical thinking and communication skills to review and analyze ethical questions and the concepts of diversity across the natural science disciplines. Through a mixture of discussions, presentations, and written analysis, students apply their previous learning in new ways, synthesizing new perspectives on their learning.

Without Concentration

Customize your degree by choosing from courses such as Microbiology, Bioethics, Advanced Investigations in Biology, Evolutionary Biology, Biodiversity, Developmental Biology, Ecology, Plant Anatomy, General Chemistry I, General Chemistry Laboratory I, Earth Science and Society, Introduction to Oceanography, Introduction to Astronomy, Physics I, Physics Laboratory I, Physics II, and the exams Anatomy and Physiology, Microbiology, Pathophysiology, Physics, Physics Laboratory, and Biopsychology. Selections must include:

  • Three or more courses from one natural/physical science discipline
  • Two or more courses from a second natural/physical science discipline
  • Electives in natural/physical sciences

Biology Concentration

At the core of careers in health care, environmental science, and energy is a background in biology: more than the study of living organisms, biology is also about big data analysis, communication of complex ideas, experimentation, and technical expertise—skills that define creative thinkers, problem solvers, and leaders. The biology concentration helps build technical and analytical skills, scientific literacy and advocacy, and curiosity about the world.

The biology concentration also enables graduates to take unique career paths, such as science journalism, public policy, forensics, or wildlife conservation. Some students pursue higher education, leading to jobs in teaching, medical research, and environmental law.

Core Biology Courses

Evolutionary Biology

Recent advances have allowed biologists to explore the genetic mechanisms that result in the diversity found in nature. In this course, students learn about the development of living organisms, from their genes to their ecosystems. Students compare what happens when an organism is under an environmental stress and how this stress affects development. Finally, they explore ethical considerations through discussions of classic model systems and current research of developmental biology.

Biodiversity

Through readings and numerous activities, this course examines the rise and fall of biological diversity over time through the study of ecology, evolution, and conservation biology. Topics include the meaning and value of biodiversity, major threats to species and ecosystems, and efforts to conserve, manage, and sustain biological diversity.

Anatomy and Physiology

This is a laboratory course that uses simulations and hands-on experiments to study body systems that include: cells, blood, integumentary system, muscular system, nervous system, skeletal system, and the endocrine system. Students use the scientific method in an experimental environment, learn and use safe laboratory practices, perform dissections, perform experiments, gather and analyze data, and present data and conclusions in scientific laboratory reports.

Plant Anatomy

Explore the anatomy of vegetative and reproductive structures of angiosperms (flowering seed plants) through the microscopic study of prepared images. This course also discusses the scientific techniques and tools scientists use to study plant anatomy and how these affect modern research. Students examine how structures of plant parts suit their functions.

Human Genetics

This course provides an overview of the field of human genetics from its beginning, Mendelian genetics, through the chromosomal theory of inheritance, the evolution of molecular genetics, to the modern techniques of genetic engineering. Learn about the applications of human genetics in the healthcare field along with topics on genetic counseling and the bio-psycho-social aspects of various genetic based diseases. Students also discuss the political and sociological implications of the ever-expanding understanding of genetics and heredity.

Microbiology

In this comprehensive introductory course in microbiology, students are introduced to cellular microbes, such as bacteria, protists, fungi, and helminthes (parasitic worms), and non-cellular microbes, such as viroids, viruses, and prions and how they are classified. The course covers the biological and biochemical foundations and scientific methods necessary to understand microbial growth and metabolism. In addition, students explore the impact of these microbes on the environment, human health, and society.

Biology Electives

Bioethics

This course introduces students to the basic concepts and principles of bioethics through critical thinking, writing, and discussing contemporary bioethical issues. Students address topics like Genetically Modified Organisms (GMO), biotechnology advances, environmental ethics, and testing on human and animal subjects. Students advance their knowledge and understanding of bioethical issues as they are encountered in daily life and learn to analyze them thoroughly and fairly.

Advanced Investigations in Biology

This course is a wide-ranging examination of advanced concepts, topics, and research methods in the biological sciences. Through virtual laboratory experiments, students explore topics including epidemiology, cardiac physiology, natural selection and evolution, and population genetics. Students also focus on strengthening their analytical and writing skills with laboratory reports.

Biopsychology

This course examines how neurons work individually and together to enable behavior, feelings, and thoughts. Students learn about the structures and functions of the nervous system and how they contribute to the biological bases of behavioral development, perception, learning, memory, cognition, motivation, language, sleep, and psychological disorders.
