Science and Computer Science

The primary goal of the science department is to engage and challenge our students with the hope of producing thoughtful citizens who have the ability, confidence, and enthusiasm to inquire about the natural world.

The science department supports these goals by promoting a durable understanding of the world through the study of chemical, biological, physical, engineering, and computer science principles. Rather than seeing each of these as separate disciplines, we encourage students to grapple with their interaction and mutual influence.

In our classrooms, we emphasize processes of inquiry and thoughtful analysis over rote recitation. We help students learn to question what they observe, to look for evidence for and against a particular viewpoint, and to design tests to collect data to develop increasingly sophisticated models. This emphasis on scientific process and creative problem solving encourages an open-minded and rigorous independence of thought that students then bring to bear on the world around them.

The science department feels strongly that students should have the opportunity to pursue advanced work in the major disciplines. We feel that this is best accomplished by a rich elective program with curricula designed to meet the interests and passions of students.

The Park School is committed to providing students with opportunities to experience all aspects of computer science and technology. Courses in the field of computer science are designed to teach engineering and design principles, while exposing students to the latest technology in hardware and software. Special interests in computer science can be handled through projects and independent study. 

Beyond computer science, a growing number of classes offered in the arts, math, science, and English departments make use of Park’s extensive technology and take place in computer and science labs, visual art and music rooms, individual classrooms, and the library.

Requirements

Two year-long courses, Core 9 (Physics, Engineering, and Computer Science), and Core 10 (Chemistry and Biology) are required for graduation. 

Core 9: Physics, Engineering, and Computer Science
Grade 9
Required
This is the first of two foundational courses in Park’s science program. Using an integrated approach, the course examines a careful selection of topics that govern the physical world such as kinematics and electricity, as well as engineering and computer science concepts that dictate the designed world. Integrations of these disciplines consist of utilizing physics as a context for engineering and computer science projects while incorporating computer and engineering skills and models to better understand physics. These concepts will be grounded in hands-on culminating experiences and projects. Throughout the year, the course provides a substantial foundation in laboratory skills with an emphasis on experimentation, design, modeling, and data analysis. Writing is also central to the course, as students learn to form a cohesive argument using both experimental data and scientific theory as support. 

Core 10: Chemistry and Biology
Grade 10
Required
Core 10 is the second of two foundational courses in Park’s science program. This integrated course covers key biological principles, such as ecology, evolution, genetics, and the environment, by grounding them in chemical concepts such as molecular structure and function, solubility, rates of reactions, and equilibrium. The foundational laboratory skills practiced in Core 9 will be expanded upon in Core 10 with an emphasis on original research and statistical significance. The course includes student-driven experimentation both in the lab and outside in Park’s extensive campus. The writing component will include exposure to primary sources of literature to support experimental findings. Throughout the year, this course will offer differentiated levels of challenge; accelerated credit is possible for students who routinely select and achieve the highest level of challenge and rigor. Prerequisite: Core 9. 

Advanced Game Creation in JavaScript

Biology 2: Ecology and Biology 2: Ecology (Accelerated)
Grades: 11-12

The natural world is all around us, but we often don’t have a well-developed appreciation for how natural systems work and function. Ecology is the study of the interactions between organisms and their environment, and we will begin the course by looking deeply into the underlying ecological processes that drive the natural world. Particular emphasis will be paid to population, community, and ecosystem level processes. Students will be exposed to ecology both in theory and practice, through lectures, readings, discussions, and various field trips and activities both in our woods and other local environments. Additionally, the concept of global change will be a constant thread throughout the course. As the footprint of human activities on ecological systems continues to expand, it is critical to understand how humans have been drivers of ecological change on multiple scales. The skills this course focuses on include field research and lab research, documentation in a lab notebook, and a heavy component of experimental design. In addition, scientific reading and writing will be required. The accelerated version of this course will assume more comfort with a faster pace while learning detail-heavy information. It will also be reading and writing intensive. Prerequisite or corequisite: Core 10. Permission of the department is required to take this for accelerated credit.
