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.
CURRICULUM REQUIREMENTS
Science is required each year from 5-8. High school students are required to take three years of science. While each science course has a focus, they are all interdisciplinary to some extent.
- Life on Our Planet is taken in 9th grade course and focuses on biology with elements of chemistry and earth science.
- Earth’s Chemical Systems is taken in 10th grade and includes chemistry and earth science.
- Physics of Our Universe may be taken in 11th or 12th grade. It includes physics and space science.
Science 5
Fifth-grade science begins with an introduction to Next Generation Science Standards (NGSS) Science Practices and then applies them using the scientific method. The students use an inquiry-based approach to explore topics in the areas of physical science, earth science, and biological science. Students utilize investigatory skills to look for patterns, relationships, and connections between various topics of the different disciplines of science. Topics covered include: the nature of properly designed experimental procedures, properties of the Earth, interaction of species and their environments, and environmental awareness and stewardship.
Science 6
In sixth-grade science, students learn about the fundamentals of Chemistry before applying that knowledge to Biological systems. Topics covered include forensic science, medical phenomena, how organisms sustain life, and how traits are passed through generations. Students examine a range of phenomena within living systems, which they explain by gathering, interpreting, and communicating evidence. Students develop skills in the Science Practices of modeling, data analysis, arguing based on evidence, and constructing explanations.
Science 7
Seventh-grade science focuses on understanding what is happening in and on our Earth. Areas studied include rocks and landforms, earthquakes and volcanoes, weather and climate, and ecosystem interactions. The course uses an inquiry-based approach with students engaging in hands-on, collaborative investigations and practicing skills including modeling and scientific writing. There is also an emphasis placed on technology and using online resources to study our earth. The seventh-grade course continues to build on the Science Practices developed in sixth grade.
Science 8
Eighth-grade science is the final course in the middle school program. It emphasizes scientific inquiry and experimentation while helping students develop their academic skills and Science Practices. Eighth-grade science concentrates on the study of physics by investigating the concepts of motion, Newton's Laws, work, energy, and power, fluid statics and buoyancy, and sound and light wave phenomena.
Life on Our Planet
In this course, ninth graders engage in the practices of science to explore life at different scales, from the chemistry of biological molecules to the global flow of matter and energy. Students explore the relationship between molecular and cellular structures of organisms and their life functions, the transmission of traits across generations, the role of evolution in driving biodiversity, and the interdependent relationships between living things and Earth’s environment. Emphasis is placed on constructing explanations for biological phenomena, including the ability to connect structure to function and model the interactions among different scales of a system.
Earth’s Chemical Systems
Life on Our Planet (formerly Biochem I)
In this course, students investigate atomic and molecular structure, chemical reactions, and conservation and transfer of energy on the atomic and global scale. Through an exploration of atomic structure, students explain trends in elemental properties, chemical bonding, radioactivity, and generation of nuclear power. Chemical bonding in turn drives differences in the physical and chemical properties of matter. Students model how substances combine and change via collisions to explain rates of reaction and energy changes. Emphasis is placed on developing particle-level models, analyzing data, and mathematical reasoning to explain phenomena.
Earth’s Chemical Systems: Honors Option
Life on Our Planet (formerly Biochem I) plus recommendation of 9th grade teacher. Algebra II is a required co-requisite.
In the honors option for Earth’s Chemical Systems, students will explore the same concepts as in the non-honors course, though the depth and pace of the course will reflect a higher level of rigor. The honors section is best suited for students who tend to pick up concepts more quickly and can master introductory problem-solving strategies with fewer examples needed. This allows the class to investigate more advanced applications of concepts and to solve more complicated problems. As an honors level course, 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.
Physics of Our Universe
Earth’s Chemical Systems (formerly Biochem II)
Physics of Our Universe is a year-long, laboratory-based course based on the Next Generation Science Standards (NGSS). The class integrates Physics, Earth and Space Science, and Engineering Practices. Topics to be investigated include Forces and Motion, Momentum and Collision, Energy, Rotational Motion, Space Science, Waves, and Electricity and Magnetism. Each unit is anchored by relevant phenomena and several student-centered labs and/or investigations. By using science and engineering practices, evidence from experiments, research, and observations, students will learn how to formulate questions, evaluate claims, use mathematics and computational thinking, and develop models to make interpretations and investigate the natural world.
Physics of Our Universe: Honors Option
Earth’s Chemical Systems (formerly Biochem II) and recommendation of current science teacher.
In the honors section of the physics class, students will explore the same concepts as in the non-honors course, though the depth and pace of the course will reflect a higher level of rigor. The honors section is best suited for students who tend to pick up concepts more quickly and can master introductory problem-solving strategies with fewer examples needed.

AP Biology
Earth’s Chemical Systems (formerly Biochem II) and recommendation of 10th or 11th grade science teacher.
This year-long course focuses on the central ideas of biology. The course focuses on fundamental principles of evolution, cell structure and function, genetics, and ecology. The curriculum is demanding its scope and its level of sophistication, with emphasis placed on the application of biological principles to explain experimentally derived data and results. Students will read a variety of materials from textbooks to online scientific journals. As an AP course, AP Biology is equivalent to a first-year college biology course and often ends with taking the Advanced Placement exam in May. 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. 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.
