Biology I is a Pre-AP level course for freshmen that covers all of the amazing and controversial realms within the great study of life.  The first semester includes Biological Themes, Biochemistry, Cells, Photosynthesis & Respiration, Cell Division, DNA, and Genetics.  The second semester includes Evolution, Taxonomy, Viruses, Bacteria, Protists, Invertebrate Animals, and Fish.  There are many fun and interesting labs throughout the year, including several animal dissections in May (like SHARKS!)

Advanced Placement Biology is a challenging class designed to be the equivalent of an introductory college course. The textbook and concepts covered are those that a freshman student majoring in biology would study.

  This is an introductory level Inorganic Chemistry Couse.  This course is designed to give a broad overview of Chemistry topics, suitable for a Pre-AP level course.  The major topics include Nomenclature, Periodic Properties and Trends, Bonding, Solution Chemistry, Acids and Bases, Reactions, REDOX, and Stoichiometry.

This AP Chemistry course is designed to be the equivalent of the general chemistry course taken during the first college year by building upon the students fist high school chemistry class.  Students will attain a depth of understanding of fundamentals and a competence in dealing with chemical problems.  The course will emphasize chemical calculations and mathematical formulation of principles, as well as implementation by laboratory exercise.

Advanced Placement Environmental Science is a challenging class designed to be the equivalent of an introductory, semester-long, college course with strong emphasis on field work.

This course is an overview and introductory trig. based Physics course.  It is intended to serve as an introduction to college Physics.  This is not an AP style course, although with additional study any student enrolled in this course could certainly take the AP exam.

This optional science course, also affectionately known as   "cat class,"  is offered in summer school for Keystone students who have already passed 9th grade Health and Biology I.  For three weeks in June, students will study detailed mammalian anatomy through the formal and careful dissection of cats, sheep brains, cow eyes, pig hearts, etc.  To earn a 1/2 science credit, students must master proper dissection skills while learning typical mammalian anatomy involving the muscular, digestive, circulatory, nervous, and reproductive systems.
