    CSIHS – Science Pathways: See Bottom
    Within the Chief Sealth Science Department, Laboratory Science classes are hands-on and designed to offer a challenging curriculum that provides students with the skills necessary for success in college science courses and in life. Various pathways or course sequences may be followed, depending on a student’s desire to simply meet graduation requirements, prepare for a four-year university, or follow a rigorous IB science curriculum. 

    *See “Pathways” insert at the end of this section for possible four-year course sequences.

    PHYSICS A/CHEMISTRY A

    Grade(s):  9
    Length of Course:  Two Semesters
    Prerequisite:  None
    Graduation Requirement Satisfied:  Science

    This course covers foundation content in Physics I and Chemistry I.  It is aligned to district, state, and national science standards and prepares students for success on state science assessments in their junior years.  

    CHEMISTRY B/PHYSICS B
    Credits:  0.5 credit / semester
    Grade(s):  10
    Length of Course:  Two Semesters
    Prerequisite:  Physics A/Chemistry A
    Graduation Requirement Satisfied:  Science

    This course covers content in Physics II and Chemistry II.  It is aligned to district, state, and national science standards and prepares students for success on state science assessments in their junior years.  Only those sophomores planning for IB Biology in their junior or senior year need to consider this course.

    BIOLOGY I, II
    Credits:  0.5 credit / semester
    Grade(s):  10, 11, 12 (Usually 10th)
    Length of Course:  Two Semesters
    Prerequisite Physics A/Chemistry A
    Graduation Requirement Satisfied:  Science
      
    This course covers fundamentals of biology and life science including: basic biochemistry, cellular biology, genetics, evolution, and ecology.  Experimental design, application, and content taught in this course will prepare students for the state EOC exam in biology.

    CHEMISTRY I, II
    Credits:  0.5 credit / semester
    Grade(s):  10, 11, 12 (10th if IB, 11th otherwise)
    Length of Course:  Two Semesters
    Prerequisite:
    Graduation Requirement Satisfied:  Science
    Other Requirements:  Must pass Chemistry I to take Chemistry II.

    Topics in this math-based Chemistry course include elements and the periodic table, atomic structure, chemical formulas and equations, mathematical relationships in chemical processes, the Big Bang and the chemistry of the universe, the laws of thermodynamics, acids and bases, gas laws, and organic chemistry. This course is a pre-requisite for IB Biology. 

    IB BIOLOGY I, II, III, AND IV – INTERNATIONAL BACCALAUREATE 
    Credits:  0.5 credit / semester
    Grade(s):  11, 12
    Length of Course:  Two Years
    Prerequisite:  Physics A/Chemistry A and Chemistry B/Physics B, or teacher permission
    Graduation Requirement Satisfied:  Science
    Other Requirements:  Must pass each semester to continue with the sequence.  

    This two-year IB Higher Level course in laboratory biology covers basic chemistry and biochemistry, cellular biology, genetics, evolution, microbiology, botany, zoology, human systems and ecology. This course is the equivalent of college biology; topics are considered in great depth. It requires a cooperative research project. An exam is taken at the conclusion of the course to determine potential college credit. Note: A student may elect to take the IB Standard Level exam after the first year of this course sequence. 

    PHYSICS I, II 
    Credits:  0.5 credit / semester
    Grade(s):  11, 12 (usually 12th)
    Length of Course:  Two Semesters
    Prerequisite:  
    Graduation Requirement Satisfied:  Science
    Other Requirements:  Must pass Physics I to move on to Physics II

    This is a full course in general physics. Students will use algebra and trigonometry to solve problems about motion, force, sound, magnetism, electricity, and light.

    HORTICULTURE
    Credits:  0.5 credit / semester
    Grade(s):  11, 12 
    Length of Course:  One Semester
    Prerequisite:  None
    Graduation Requirement Satisfied:  Science

    This course introduces the student to the general field of horticulture and environmental science. Students will learn about horticultural cultivation techniques, plant identification, and growth requirements, with a special emphasis on urban horticulture and sustainable practices. Indoor and outdoor learning components broaden scope and provide opportunities for knowledge application.  

    ANATOMY AND PHYSIOLOGY
    Credits:  0.5 credit / semester
    Grade(s):  11, 12 
    Length of Course:  One Semester
    Prerequisite:   None
    Graduation Requirement Satisfied:  Science

    Students in Anatomy and Physiology will develop an understanding of the organization of the human body through studies of body systems, tissues and cell chemistry.  Computer simulations and/or dissections of various body parts (using animal specimens) will be used to show how anatomy (structure) relates to physiology (function).  

    CSIHS Science Course Pathways – An Overview

    The four columns in the table below represent typical pathways for science students at Chief Sealth. Although the Seattle School District graduation requirement is just two years of laboratory science, students are encouraged to take more science classes both to broaden their exposure and to better prepare themselves for higher education. 

    Notes: 
    1. Column 1 is really only to identify the minimum requirement. The Science Department urges all students to take as many science courses as their interests and abilities allow. 
    2.  At this time all Freshmen students are enrolled in Physics A/Chem A. Following the 9th grade year, most students should enroll in Biology. Some students – i.e. those who have decided to pursue IB Science courses as shown in columns 3 and 4 – will enroll in Chemistry. *Strong Algebra and Science Skills are required for success in Chemistry.  9th grade Students with low math and/or science grades should consult with their counselor and science teacher before enrolling in Chemistry for their Sophomore year.
    3.  While only four common paths are shown, the table is not intended to be restrictive. For example, a student might take Physics A/Chem A, then Chemistry and then drop back to take Biology. When students think about their four-year sequence they need to remember that Counselors and Science teachers will always encourage broad exposure instead of narrow focus.

    CSIHS Science Course Pathways – IB Courses

    Notes: 
    1.  SL = a “Standard Level” course, one year in duration. Covers general core concepts and several additional content options to choose from. HL = a “Higher Level” course, two years in duration. Covers general core more broadly and more deeply and also includes several additional content options to choose from. 
    2.  A student could still complete the “full IB diploma” with only one IB SL science course, but would need to take 3 HL courses in other subject areas
