The Science Department aims to inspire a life-long love for learning by fostering curiosity and encouraging positive risk-taking. The expectations are to develop critical thinking skills with an appreciation of and respect for an ever-changing world of science.
Through a creative, open-ended, multi-sensory, interdisciplinary curriculum, students become scientifically literate stewards of the environment and humankind.
Biology I is the core class in the Country Day science curriculum, required of all current students and transfers who have not completed a comprehensive lab course in high school biology. This course develops the skills and lab experience necessary to move on in the sciences. Most students move on to Chemistry and Physics in their sophomore and junior years.
Current students entering 9th grade and students new to the school have the option to take Inquiries in Biological and Physical Science before taking Biology 1. This qualifies as one of the three required years of science for graduation.
The foundations of Biology I and Chemistry I give students the necessary fundamentals to take on upper level AP and IB sciences. In addition, the science department offers a rich array of electives in the life sciences and physical sciences so that students can pursue their unique interests.
Inquiries in Biological and Physical Science
Full year. This foundational class will introduce a range of topics from life and physical sciences while emphasizing critical reading and thinking, the scientific method, and lab skills. It is designed to be taken before Biology I and will prepare students for that class and the physical science classes to follow it. Students will complete a broad lab curriculum that covers aspects of measurement, data recording and processing, along with analysis of results and drawing conclusions. Topics studied will include cell biology, ecology, earth science, conceptual chemistry, chemical reactions, materials science, and conceptual physics.
Full year. Required for any subsequent science course. A conceptual and lab-based survey of basic Biology with emphasis on the scientific method, biochemistry, cell structure and function, genetics, biotechnology, human systems, and evolution. Rather than focusing on a body of
facts, the course uses broad themes and questions to guide student learning by drawing connections between the different aspects of Biology. Intentional development of study and laboratory skills is integral to the course.
Full year. Prerequisites: Biology I, Chemistry I or Honors Chemistry I, and qualification. This college-level survey course includes the study of cellular and molecular Biology, signal transduction, Biotechnology, Genetics, Evolution, diversity of living things, animal form and function, populations, and ecology equivalent to a two-semester introductory level Biology course. The course explores science as a process, uses personal experience in scientific inquiry, and applies biological knowledge and critical thinking to environmental and social concerns. The goal of the course is to develop advanced inquiry and reasoning skills, application of mathematical routines, and connection of concepts in and across domains structured around four big ideas. Extended lab time is required, and students are expected to sit the AP Biology exam.

in 2022-2023. It will be offered next in 2023-24. Prerequisite: Biology I, concurrent enrollment in Algebra II or higher. Practical Biology will focus on what students often enjoy most about their science classes: performing experiments. In this course, students will learn new techniques and reinforce those learned in prior biology courses. Areas of investigation will include plants,
ecology, cellular biology, genetics, biotechnology, and physiology. Students will learn both the basic biology and lab techniques associated with each of the above topics. Field trips will occur during the plans and ecology units to sites near the school or to local parks. The course will
culminate in a student-designed investigation, rather than having a final exam. The course is open to grades 10-12.
Second semester. Prerequisite: Biology I. This semester course is a survey of the basic concepts of Marine Biology. Topics include the interdependence of organisms to each other and to their environments, properties of water, the physical and chemical dynamics of marine environments, food webs and trophic dynamics, marine plants, marine invertebrates and vertebrates, adaptation of marine organisms, and a survey of selected marine ecosystems. Students study
these topics through readings and discussions, hands-on activities, and participation in a mandatory overnight field trip to Charleston. The course is open to grades 10-12.
Second semester. Please note: this course is offered in alternate years and is available in 2022-2023. Prerequisite: Biology I. The semester course examines ethical issues surrounding
controversial applications of biotechnology. Major topics will include genetic modification, genetic screening, stem cells, and cloning. Students will be challenged to consider the ethical implications of these topics while demonstrating an understanding of the science behind
the issues. To accomplish this, students will participate actively in class discussions, carry out complex labs with accuracy and efficiency, debate ethical topics and scenarios, compose detailed lab reports, and write in-class essays. Rather than taking a final exam, students will
complete a final project of their choosing on a bioethical issue. The course is open to grades 10-12.

Students with skills in Chemistry, Biology, Physics and Computer Science are especially needed to create 3D printed models that can be used to
further our understanding of biochemistry. Small groups of students with weekly targets to solve problems will work towards the ultimate goal of developing an improved physical model. It is expected that students will keep track of their hours, present their progress at weekly group meetings and write a literature review and a final research paper in collaboration with their group. Students will work with professors around the country and may publish findings and/or present at conferences as the work progresses. Due to the unique nature of this course, there are no grades assigned, only transcript credit. Please see the group website: www.ccdsbiochem.com.
