Every student is required to take three years of science in order to graduate from PHS. The sequence of courses furnishes students with a broad base in the scientific method in three core sciences – physics, chemistry and biology. In addition students have the opportunity to explore, in greater depth, topics which are of greater interest to them. This can be accomplished by enrolling in one of many elective courses in either the life and/or physical sciences.

All science courses rely heavily on the discovery/inquiry method whereby students invest much of their class time performing a variety of laboratory experiments.

The PHS Science Department encourages students to explore science through the study of life sciences and physical sciences. Upon graduation students are expected to be able to:

  • Demonstrate understanding of the scientific method.
  • Apply the scientific method to the solution of a problem.
  • Demonstrate understanding of relationships between structure and function.
  • Demonstrate the ability to apply biological concepts to everyday life.
  • Understand the relationship between plants and animals.
  • Use math skills as they relate to interpreting data, graphing of data and problem solving.
  • Interpret and communicate results of laboratory investigations.
  • Analyze and interpret data from tables and/or graphs (i.e., recognize patterns, regularities, trends and anomalies).
  • Distinguish between scientific concepts and opinions.

Class Name
Biology
This Biology course has three major concepts for the focus of instruction: 1. Interactions of the organisms in an environment are determined by the biotic and abiotic components of the environment.  2.  The structures in all living things occur as a result of necessary functions.  3. Evolution of species occurs over time and is related to the environment in which the species live.  We begin with ecology and continue with the study of cells, genetics, evolution, classification of living things, and finish the year with a study of organs and organ systems..

Chemistry
This is an introductory course in theories and concepts of modern chemistry. The course emphasizes the atomic and molecular structure, chemical bonding, stoichiometry, properties of gases, solutions, reaction rates and equilibrium, acid‐base reactions, and chemical thermodynamics. The student will be introduced to quantum mechanics, organic and biochemistry, and nuclear chemistry. 
Chemistry Honors
This is an introductory course in theories and concepts of modern chemistry. This course is designed to prepare students for college chemistry. Topics will be presented to increase awareness and understanding of the role of chemistry in everyday life and environmental issues. The course emphasizes the atomic and molecular structure, chemical bonding, stoichiometry, properties of gases, solutions, reaction rates and equilibrium, acid‐base reactions, and chemical thermodynamics. The student will be introduced to quantum mechanics, organic and biochemistry, and nuclear chemistry. The laboratory work will develop students reasoning power, the ability to apply chemical principles; as well as acquaint students with chemical laboratory techniques. 
Earth & Space Systems: Section B/1
This course is the study of the universe, solar system and earth. The study is very exciting because these are concepts that you can observe in the world around you. Understanding the way that the world works can be very fascinating.
Earth & Space Systems Honors: Section C/1
This course is the study of the universe, solar system and earth. The study is very exciting because these are concepts that you can observe in the world around you. Understanding the way that the world works can be very fascinating.
Physics Honors: Section C/4
Physics is considered the study of everything. Everything is physics and physics encompasses everything. Matter, energy, forces and waves will all be topics we will learn about this year. The study is very exciting because these are concepts that you can observe in the world around you. Understanding the way that the world works can be very fascinating.
