Challenging girls to become women of 
intellect, character, innovation, action, and faith


Upper School girls in science lab working with test tubesThe science program is based on the philosophy that guided inquiry is important to understanding scientific phenomena, including how biological, chemical, and physical interactions contribute to our daily lives. Stimulating class discussion and hands-on experimentation help students develop skills to connect scientific principles, collaborate with peers, process and evaluate scientific information, draw conclusions, and communicate their work orally and in writing. Emphasis is placed on data collection and interpretation, critical thinking, inductive and deductive reasoning, problem solving, and the use of evidence to support claims. 

Girls in Grades 7 and 8, and Upper School students participating in Independent Research, present their projects to a group of judges at the annual Science and Engineering Fair.

Middle School

Science 5 - Ecology and the Environment

Students investigate the world that we live in through a series of interactive activities, multimedia sources, classroom discussions and tidepooling activities at the Halibut State Park fieldtrip, learning about both terrestrial and aquatic biomes and our own impact on the environment. They examine various interactions between organisms, environmental issues, and special properties of water. Students are encouraged to observe, question, think about interrelationships among topics, and learn from their experiences. Through guided practice, students begin to hone their time management, organizational, study and critical thinking skills.

Science 6 - Geology, Meteorology, and Astronomy

Through a series of laboratory activities, multimedia sources, classroom discussions and astronomical activities at the Christa McAuliffe Center fieldtrip, students begin to uncover some of the great mysteries of our universe. They journey from the interior of the Earth into the atmosphere and beyond to learn about space, plate tectonics and weather. Students are encouraged to question, think thoroughly, extrapolate from their own experiences, and clearly articulate their ideas in both the written and spoken word. They also practice making direct and indirect observations, looking for patterns in and connections among their data, and crafting persuasive arguments.

Science 7 - Life Science

This course is designed to give students an overview of the natural sciences and prepare students for Biology 9. The first semester begins with a discussion of what science and the scientific method of discovery are. This leads to the discovery of what makes something living or non-living and students will learn about the differences among plant, animal, and bacterial cells. The course then moves to the Linnaean system of classification of living things, and a study of the Domains and Kingdoms. During a study of the Plant Kingdom, students will dissect a flower to study its reproductive system. The course then progresses to the study of viruses, bacteria, and infectious diseases, along with human anatomy. Class time will consist of lectures, group discussion, dissections and other small group work.

Skills that will be emphasized in class include organization, learning how to use a microscope, handling dissection equipment, learning how to write using scientific language, and creating an independent research project for our Science and Engineering Fair using the scientific method. At times during the course of the year, students will design their own laboratory experiments in groups.

Science 8 - Physical Science

This course introduces students to the fundamental principles of physics and chemistry and prepares them for the study of science at the Upper School level. Girls learn about the engineering design process and apply knowledge gained through readings, class discussions, and demonstrations to solve real-life engineering problems. Students use an inquiry-based approach to formulate questions, design experiments, and make predictions about physics and chemistry phenomena. They build, test, and modify a prototype as part of an independent engineering project, which they exhibit at our Science and Engineering Fair. Topics covered in the course include motion, forces, energy, work and machines, matter, and elements and the periodic table.
