# Physics

## GENERAL STUDIES

### Course Description:

Physics provides a hands-on experience with the basic principles of physics, as well as
rigorous practice using logical thinking skills. Students use sophisticated computer tools
to gather and analyze data about simple physical phenomena and use their results to
They then confirm or refute their predictions by experiment. Topics include mechanics,
thermodynamics, electricity and magnetism, light and optics, and waves and sound.
Additional emphasis is placed on the development of computer and laboratory skills.

### Course Objectives:

Students will be able to:

• Identify questions and concepts that guide scientific investigations;
• Design and conduct scientific investigations;
• Use technology and mathematics to improve investigations and communications;
• Formulate and revise explanations and models using logic and evidence (critical
thinking);
• Recognize and analyze explanations and models; and Communicate and support a scientific argument.
