MADISON PUBLIC SCHOOLS Enriched Physics Authored by: Jennifer Freeman, Luis Largo, Carole Rawding Reviewed by: Lee Nittel Director of Curriculum and Instruction Tom Paterson K12 Supervisor of Science and Technology Date: Fall 2012 Members of the Board of Education: Lisa Ellis, President Patrick Rowe, Vice-President David Arthur Kevin Blair Linda Gilbert Shade Grahling Thomas Haralampoudis James Novotny Superintendent: Dr. Michael Rossi Madison Public Schools 359 Woodland Road, Madison, NJ 07940 www.madisonpublicschools.org I. OVERVIEW This laboratory-based course is designed to introduce students to a comprehensive, conceptual and quantitative study of physics. Actual observations of real physical phenomena, in and out of the laboratory, are examined and interpreted through theoretical discussions and general problem solving. Emphasis is placed on thoughtful observation, interpretation and finally explanation of physical phenomenon. Students are encouraged to construct new knowledge beyond their existing schema. Student misunderstandings are addressed with the intentions of building new, more sophisticated understanding of the concepts. Multiple representations are used to reinforce concepts including a quantitative mathematical approach to physics. The units include motion and forces, momentum and energy, heat, electricity and magnetism, waves and sound, and light. II. RATIONALE Physics concepts are fundamental to all of the sciences. This course is designed to give the students an opportunity to explore these underlying concepts as they apply to their everyday experiences. Upon completion of the course, the student will have the ability to more fully describe, discuss and explain many phenomena. Students learn how the ideas they study in physics can be used in concert with the ideas of the other sciences. Students also learn how physics can help to promote new technologies. Students will learn to collaborate through the use of teams. Students develop reasoning power through problem solving supported by algebra-based mathematics. They increase their ability to communicate clearly when explaining results and relationships and improve their ability to be good citizens of both the global community and their own local community.

STRATEGIES Development of concepts takes place in thematic units. Each unit is designed around laboratory experiences, hands-on activities and collaborative learning stations. Students use inquiry-based labs to explore conceptual themes. Introduction of applications early in the teaching of topics is applied to help students form their understanding. Demonstrations, software and internet driven computer simulations and interactions are utilized to encourage student engagement to discover, apply and verify, and extend concepts. Problem solving situations using multiple representations are created for students to develop the ability to interpret, analyze and solve authentic problems. Problems are also presented to allow students to design and interpret their own experiments. Both group and individual problem solving time is utilized. Students learn to develop models to represent their understanding. Assessment of student learning, both formative and summative, is approached to fully value each student’s abilities. VII.
