Course Description

 

 

 

This fast-paced Physics Honors course is designed for a highly motivated student with strong mathematical ability who plans to pursue a career in life sciences, medicine, geology, mathematics, physical science, engineering, or related fields.  It is also meant as a preparation course for the Advanced Placement Physics B course that is offered as a second-year physics course at Glen Ridge High School.

 

The major goals of the course are to study the interaction of matter and energy through the mastery of the basic principles of physics, and to apply these principles -- using the scientific method--to the solution of problems.  Analytical methods involving freshman college level mathematics are emphasized throughout the course.  Problem  solving is a major component of this course!

 

Laboratory work is performed and designed to discover or to apply the basic principles of physics. 

 

As of this writing, we are experimenting with the content of this fast-paced Honors Physics course (based on the AP Physics B curriculum) and time constraints set by the school year.

SCIENCE MISSION STATEMENT

 

 

The Glen Ridge Public School’s science curriculum seeks to develop scientifically literate life-long learners through a program that fosters a spirit of wonder, intellectual curiosity and collaborative problem solving that is authentic, hands-on, inquiry based and developmentally appropriate.  This is done through the study of Life, Physical, Earth and Environmental science.

 

Our students will use the scientific method to understand and respond to questions about science, technology, and societal and world problems.  Students will be challenged and encouraged to take risks and to develop critical thinking skills as they apply to real-world experiences.

 Physics Honors Curriculum Description

As of this writing, we are experimenting with the content of the Physics Honors course and the effect of time restraints.

Currently, the content of this fast-paced Physics Honors course will follow a major portion of the AP Physics B course curriculum on an introductory level: 

·        Fundamentals

·        Newtonian Mechanics,

·        Electricity and Magnetism, and

·        Waves and Optics.

It is our intention that the second-year AP Physics B course

would then complete the AP Curriculum with

 

·        Fluid Mechanics and Thermal Physics

·        Atomic and Nuclear Physics

 

    and  review the entire AP Physics B curriculum.
