About

The need to understand and apply science has never been more essential to society than it is in the 21st century. Advancements in medicine, technology, and access to information have changed the landscape of our world. Further, the impact of humans on our environment has made the question of sustainability a crucial topic of study. As a result, science education is critical to the development of both informed citizens and the preparation of our next generation of scientists and engineers. The Science Program at St. Mark’s aims to develop students who are scientifically literate, create opportunities for the interdisciplinary study of STEM (science, technology, engineering, and mathematics), and provide an exemplary preparation for collegiate level science. In an effort to meet these goals the program engages students in the process of science through the study of the core ideas that pervade the discipline: energy and matter, form and function, cause and effect, the use of models, and observation of patterns. Students explore these ideas while developing the practices that are central to the scientific enterprise itself such as observing, questioning, testing, analyzing, applying, designing, developing evidence-based arguments, and communicating. Each course is designed around a core set of ideas and grounded in context, all of which provides students with an increased understanding of the natural world, empowers students to propose solutions to dynamic problems, and better equips students to make informed decisions based upon science.

Courses

Core Science Pathways

Physics

This course covers the major concepts in physics through the context of engineering design challenges. There will be extensive focus on developing good problem solving techniques, learning about engineering methodology and design, and introducing proper communication, collaboration, and writing habits. Topics covered include kinematics, the laws of motion, momentum, energy, the properties of waves, and electricity and magnetism. Experimental design, data analysis and their use in making engineering decisions are a main feature of the course. During designated “build days” students have the opportunity to apply their knowledge in an engineering context that focuses on making and learning from mistakes in an authentic setting. Students complete several of these design challenges over the year and are encouraged to relate the concepts learned in class to 21st century themes and events.

Chemistry

Honors Chemistry is an interactive introduction to the discipline of chemistry. In covering topics such as atomic structure, bonding, stoichiometry, and gas laws, students develop an appreciation for the chemistry present in the world around them. As students, they are challenged to grow as problem solvers both in the laboratory and in classroom settings. Small group work is emphasized as a way to encourage discussion of topics, as well as provide opportunities for students to learn collaboratively. Work in the laboratory enhances understanding of content, while laboratory reports provide students a venue in which to develop their technical writing skills. Students in the Honors course should feel comfortable moving through the material in class at a quicker pace, as well as possess greater comfort with self-directed learning. The Honors Chemistry class is strongly recommended for students interested in taking Advanced Chemistry. (Prerequisite: Physics and Departmental permission)

Biology

The study of Biology has never been as complicated or exciting as it is today as our understanding of the living world is increasing at an unparalleled pace. Advancements in science blur the line between living and nonliving and our ability to control and direct life processes continues to evolve rapidly. This course provides students an introduction to the study of biology within the context of a rapidly changing world. Students will explore the ideas of ecological, cellular, and genetic change through consideration of three types of sustainability: environmental, economic, and social. The course of study will incorporate a variety of learning approaches such as inquiry, lab design, presentations, collaborative study, problem-based learning, case studies, simulations, and scientific writing. Each unit will culminate in a final project that will encourage application of new knowledge and understandings to a ‘real world’ situation, often without one specific right answer. There will be a heavy emphasis throughout the course on developing students’ analytical writing skills as well as their ability to specifically utilize direct evidence to back up all claims and arguments. (Prerequisite: Completion of Chemistry)

Advanced and Elective Science Courses

Engineering: Structures and Materials

Fall & Spring

Structures and Materials provides a one-semester introduction to mechanical engineering. Using a thematic approach, students will work together on solving a semester long challenge that could involve a project like designing and building a “green” electric race car, a device to assist people with impaired mobility, or an invention designed to solve a problem in a developing country. Throughout, the students will perform many design/test cycles and keep track of efficiencies of performance relative to energy, weight, and/or cost. Inverting the traditional ratio of lecture to lab time, students spend a major portion of their class time involved in hands-on work, directed toward solving the challenge. No prior knowledge of use of tools or work safety is assumed, but will be an ongoing component of the course. Students will be introduced to the concepts of mechanic stress and strain, then perform experiments to determine Young’s modulus, yield strength and ultimate strength of representative materials. They will discover modeling and simulation CAD software, and then build prototypes they will subsequently test. (Open to all Forms. Prerequisite: Physics)

Exploration Sciences: Air and Space

Fall

Similar to Exploration Sciences: Land and Sea, Exploration Sciences: Air and Space will continue to address topics related to human beings innate and passionate need to explore and discover. Through this course, students will explore what it means to discover and push the limits of their world. Students will briefly examine what it takes to be an explorer: the common personality traits, skills, and methods that are utilized by explorers of our atmosphere and space. Course work will be a mix of a more traditional survey type astronomy course and coursework focused on space engineering and exploration principles. In the survey course setting, students will work on understanding topics related to basic astronomical concepts, astrophysics, astrochemistry and astrobiology. Students will understand definitions and functions of astronomical bodies, the solar system, the Milky way, star formation, and basic universe theory. They will explore concepts and issues related to earth’s atmosphere and apply those to understanding how other planets’ and moons’ atmospheres operate. The remainder of the course will be focused on exploration techniques related to space and our atmosphere. Students will learn about how known planets and moons are analyzed and explored and how new stars, planets, and other celestial bodies are discovered through multiple techniques. There will be multiple engineering projects related to these ideas. These include high atmosphere exploration and data collection, rocketry, and decent vehicles.(Prerequisites: Physics, Chemistry, and Biology -- one course may be taken concurrently)

Exploration Sciences: Land and Sea

Spring

Human beings have yearned to learn more about themselves and the world around them since they became aware of their surroundings. They have always pushed the boundaries of understanding by exploring further than their known world. Every human has an innate and instinctive passion for discovery; this course will work at feeding that desire. Through this course, students will explore what it means to discover and push the limits of their world. Students will examine what it takes to be an explorer: the common personality traits, skills, and methods that are utilized by explorers. Land unit topics will involve concepts such as geology, geography, and ecology and how scientists and explorers examine the land we live on. They will learn how to use a compass, gps, and map, along with creating a detailed map of campus and completing an ecological survey. Students will consider the depths of the ocean, a vastly underexplored area of our earth, and investigate ways to explore the unreachable. Projects that students will work on include building an underwater ROV (remote operated vehicle), hiking trail development, and various field studies of areas on campus. (Prerequisites: Physics, Chemistry, and Biology -- one course may be taken concurrently)

Topics in Biotechnology

Within each Module students build their understanding of the tools and technologies that are foundational in biotechnology as well as examine their application. Students also have the opportunity to explore biotechnology through an interdisciplinary lens - thus allowing learners to consider how our changing understanding of life and our ability to manipulate life impacts society in areas such as, but not limited to, ethics, law, psychology, economics, and politics. This course is designed to be highly student-directed. In this course learners will have lots of opportunity for choice - choice in how they learn, how they demonstrate their learning, and in some cases - what they learn. With this choice comes significant responsibility. Students who enroll in this course should be prepared to be challenged as self-directed learners. Students will be expected to deeply reflect upon how they learn best, select learning pathways that will both support and challenge them as individuals, and expand their ability to demonstrate understanding. A digital portfolio will be used to manage and demonstrate learning. (Open to V and VI Formers. Prerequisite: Biology or Advanced Biology)

Case Studies in Anatomy and Physiology

Spring

Case Studies in Anatomy & Physiology is an elective science class for students who have successfully completed Biology and are motivated to examine this subdiscipline within a problem-based, collaborative structure.
