Science

Rooted in our Catholic and Marianist identity, the science program affirms academic and intellectual excellence as essential to the formation of the whole person. Through rigorous scientific inquiry, hands-on laboratory experiences, data analysis, and problem-solving, students develop critical thinking skills and an appreciation for the order and complexity of God’s creation. In the Marianist tradition, science education fosters a community of learners, encourages adaptation and innovation, and promotes education for service, justice, and peace. By integrating faith and reason, the program emphasizes ethical reflection, stewardship of the natural world, and responsible decision-making. Students are challenged to apply scientific knowledge with integrity and compassion in service of the common good, preparing them for continued academic success and responsible citizenship.

GRADUATION REQUIREMENTS

3 credits in Science must include one unit of physical sciences, one unit of life sciences and one unit of advanced study in one or more of the following sciences: chemistry, physics or other physical science; advanced biology or other life science.

COURSES

Biology

Academic Pathway: Honors, College Prep

Term: year-long course

Credit: 1 full science credit

This is a laboratory-oriented course designed for freshmen. The course provides an in-depth experience of biochemistry and cell biology and reinforces these concepts throughout the year. Topics include the cell, photosynthesis, cellular respiration, protein synthesis, genetics, evolution, and ecology. Emphasis is given to developing critical thinking and problem-solving skills. Students are to work both collaboratively and individually to solve problems and investigate the latest information in biology. The course material extends beyond the classroom with experiences that apply to daily life.

Chemistry

Academic Pathway: Honors, College Prep

Term: year-long course

Credit: 1 full science credit

This course introduces basic topics of chemistry using an in-depth and mathematical approach. Topics covered include measurement and problem-solving, atomic structure, chemical bonding, the mole concept, the periodic table, nomenclature and equations, stoichiometry, and solutions. Some concepts have a strong mathematical emphasis. Concepts covered in class are applied to lab experiments and other activities.

Physical Science

Academic Pathway: College Prep

Term: year-long course

Credit: 1 full science credit

Have you ever wondered why some metals are magnetic, but others are not? Or how do eyeglasses correct our vision? And how much solar energy can we get from the sun? In Physical Science, we will answer these questions and many more! We will cover introductory topics in chemistry –like how the number of electrons determines how elements bond with (or refuse to bond with) each other. Then we branch into physics, where we will explore how and why things move as they do. Finally, we will wrap up the year exploring the stars and planets in our solar system! In addition to all of this, you will learn how scientists conduct their experiments and how scientific discoveries influence our everyday world.

SL IB Environmental Systems and Societies (Year 1)

Academic Pathway: IB

Term: Two-year course

Credit: 2 full science credits

ESS is a complex course that requires a diverse set of skills from its students. It is firmly grounded in both a scientific exploration of environmental systems in their structure and function and in the exploration of cultural, economic, ethical, political, and social interactions of societies with the environment. As a result of studying this course, students will be equipped to recognize and evaluate the impact of our complex system of societies on the natural world. The interdisciplinary nature of the course requires a broad skill set from students, including the ability to conduct research and investigations and to participate in philosophical discussions. The course requires a systems approach to understanding and problem-solving in environmental contexts and promotes holistic thinking about environmental issues. It is recognized that to understand the environmental issues of the 21st century and suggest suitable management solutions, both the human and environmental aspects must be understood. Students should be encouraged to develop solutions from the personal to the community and global scales. Through the exploration of cause and effect, the course investigates how values interact with choices and actions to produce a range of environmental impacts. Students develop an understanding that the connections between environmental systems and societies are diverse, varied, and dynamic. The complexity of these interactions challenges those working to understand the actions required for effective guardianship of the planet and the sustainable and equitable use of shared resources.

Physics

Academic Pathway: Honors

Term: year-long course

Credit: 1 full science credit

Honors Physics is a rigorous course that introduces students to the fundamental principles governing the physical world. Through inquiry-based learning, students develop scientific reasoning, quantitative problem-solving skills, and a deeper appreciation for the order and beauty of creation. Students explore core topics including measurements and uncertainties, mechanics, thermal physics, and waves. Emphasis is placed on developing strong laboratory skills, analyzing experimental data, and communicating scientific findings with clarity and precision. Mathematical modeling and conceptual understanding are integrated throughout the course to prepare students for advanced study in physics and related fields. Aligned with the values of Purcell Marian High School, students are encouraged to ask meaningful questions about the natural world, collaborate in a spirit of community, and reflect on the ethical and societal implications of scientific and technological advancement.

SL IB Environmental Systems and Societies (Year 2)

Academic Pathway: IB

Term: Two-year course

Credit: 2 full science credits

Anatomy and Physiology

Academic Pathway: College Prep

Term: year-long course 

Credit: 1 full science credit

Prerequisites: CP Chemistry or equivalent

This course offers an in-depth exploration of the human body and its systems. Students will study the structure and function of major body systems including the skeletal, muscular, circulatory, respiratory, digestive, nervous, and reproductive systems. Emphasis will be placed on how these systems work together to maintain homeostasis and support life. Students will engage in hands-on activities, dissections, and laboratory experiments to enhance their understanding of anatomical structures and physiological processes. Topics will also include cellular biology, the role of genetics in health, and the impact of diseases and disorders on the body. This course is ideal for students interested in pursuing careers in health science, medicine, or biological research.
