Science

The aim of the Overlake School Science Department is to capitalize on students’ curiosity to engage them in a rich exploration of the natural world. By investigating natural phenomena and scientific issues, students will become more critical and ethical science practitioners. Students will learn to appreciate the complexity of the natural world, learn how to apply scientific methods to explore phenomena, and appreciate the contributions of diverse people in advancing scientific knowledge. 

Throughout the course of their Overlake Career, students at Overlake will master a core set of Science Practices that align with Next Generation Science Standards (NGSS): 

  • Asking questions and defining problems 
  • Developing and using models 
  • Planning and carrying out investigations 
  • Analyzing and interpreting data 
  • Using mathematics and computational thinking 
  • Constructing explanations and designing solutions 
  • Engaging in argument from evidence 
  • Obtaining, evaluating, and communicating information 
  • The Science Practices are designed to spiral through the grade levels – skills students learn in one grade will become further developed in later years.  

During the required years of study, students encounter concepts, principles, laws, and practices of science at successively higher levels of abstraction. The required course of study is designed to immerse students in the investigation of the nature and behavior of matter, energy, and living organisms. The departmental requirements prepare students for more advanced study both at Overlake and at college, as well as helping them develop an appreciation for the important role of science in their everyday lives. 

The department staff is committed to active learning experiences, engaging the students in the process of science via lecture, discussion, inquiry, and laboratory work. Science teachers are also committed to intellectual integrity and personal responsibility. They will help students take pride in their own growth and the development of their abilities as young scholars. Honest effort and full engagement serve to enhance the students’ ability to think critically, communicate intelligently, and understand the wide range of people who have contributed to scientific discoveries and achievements.

AP Chemistry

Science
Year-long elective open to 11th and 12th grade students.

Earth’s Chemical Systems (formerly Biochem II) and recommendation of 10th or 11th grade science teacher.

This year-long, college level course expands upon many of the topics introduced in earlier courses. Students will begin with a study of the nature of matter, examining topics ranging from atomic structure to the structure and properties of matter to chemical reactions. An in-depth, experimental approach to the study of the behavior of matter will occur through an examination of reaction kinetics, equilibrium systems, and thermodynamics. Laboratory work plays a key role in the structure of the course, with emphasis placed on the application of chemical principles to explain experimentally derived data and results. While the Advanced Placement test is an important goal, emphasis will be placed on developing critical thinking and problem-solving skills. As an AP course, AP Chemistry is equivalent to a first-year college inorganic chemistry course. Therefore, it is expected that students enter the course with strong work habits, complete homework on a nightly basis, read independently for understanding, and demonstrate self-advocacy skills. Students should expect to spend roughly an amount of time working outside of class equal to that spent in class. Lab reports and special projects may add to this time.
