SPH4U: COURSE OUTLINE

Transcription

1 SPH4U: COURSE OUTLINE COURSE OUTLINE This course will enable students to deepen their understanding of physics concepts and theories. Students will investigate a variety of physics concepts including kinematics, dynamics, momentum, light, electricity, magnetism, modern physics and more. Throughout the course students will improve their scientific investigation skills by learning how to qualitatively and quantitatively analyze data related to a variety of physics concepts and principles. Students will also explore technological applications of physics and their effects on society and the environment. CLASS REQUIREMENTS textbook Physics three-ring binder scientific calculator pencils, erasers, ruler lined paper LEARNING SKILLS In addition to course expectations students are to demonstrate and be assessed in each of the following six learning skills: Responsibility, Organization, Independent Work, Collaboration, Initiative and Self-regulation. The learning skills are evaluated as Excellent, Good, Satisfactory, or Needs Improvement. ASSESSMENT STRATEGIES A variety of assessment strategies including, but not limited to quizzes, tests, assignments, investigations, laboratory experiments, exams and projects will be used to assess students learning. EVALUATION Marks Knowledge and Understanding Thinking and Inquiry Communication Application Term (70 %) 20 % 20 % 15 % 15 % Final Evaluation (30 %) The final exam will incorporate all of the categories. UNIT DESCRIPTIONS Unit 1: Kinematics and Dynamics Students will explore motion in 2-D, representing displacement, velocity, acceleration, projectile motion, and coordinate systems using vectors, graphs, and mathematical equations. In dynamics, students will learn about free body diagrams, Newton s Laws of Motion, and uniform circular motion, making connections to kinematics and real world applications. Unit 2: Energy and Momentum In this unit students will explore energy transformations and he forces that affect the motion. Students will apply their knowledge of kinetic energy and potential energy from previous years and build upon them. A strong focus on conservations of energy and collisions will be present in a variety of problems students will explore and solve. Exploration in careers and renewable energy sources will be explored in this unit. Unit 3: Gravitational, Electric, and Magnetic Fields Students will investigate gravitational, electric and magnetic forces and how they act on objects from a distance. Next students will explore the concept of a field and the properties and behaviour of gravitational, electric and magnetic fields, and how to describe these attributes mathematically. Students will then apply their knowledge while exploring the technological systems that involve gravitational, electric, and magnetic files, and their effects on society and the environment.

2 Unit 4: The Wave Nature of Light This unit focuses on relating the properties and characteristics of light to similar properties and characteristics found in mechanical waves. Students will mathematically and qualitatively interpret refraction, reflection, diffraction and interference of waves. Students will then explore applications of the wave nature of light such as single slit diffraction, interference in thin films, and the electromagnetic spectrum. Unit 5: Modern Physics This unit focuses on introducing physics concepts that are pertinent to the subject as it is studied today. Students will identify the conceptual problems encountered by physicists at the turn of the 20th century, and learn how the development of special relativity and quantum mechanics redefined our understanding of the physical universe, and the effects their progression have had on physics today. RATIONALE For Time Spent on Each Unit and Order of Units The units are ordered so that knowledge learnt in one is useful for another. For example, vectors are introduced in the beginning since kinematics since this is vital to dynamics, momentum, electricity and magnetism. They are sequenced in a way that provides logical connections to topics. The modern physics unit comes toward the end since student require prior knowledge before introducing these more difficult concepts. Time spent on each unit correlates to the amount of material needed to be covered and the importance of each topic to higher physics. Unit 1 spends a large amount of time building mathematical skills with vectors/trigonometry and problem solving skills that are carried into the later units. Unit 2 uses prior knowledge on potential and kinetic energy to build upon more advanced problems, as well as applying energy conservation laws to 1D and 2D elastic and inelastic collisions. Unit 3 takes up a fair amount of time as it encompasses many different topics. This unit is very dense and is usually a difficult unit for students. This unit builds on previous skills but also involves many new concepts. Unit 4: The Wave Nature of Light spans over 14 lessons. There are two chapters in the Wave Nature of Light that encompasses several important derivations. Although the derivations take some time to go over, the equations themselves are easy to rearrange and work with. Students will have time after each lesson to go over practice problems so a work period is not a necessity. Unit 5, as the last completed unit of the course, focuses on introducing students to the concepts and theories that have led to current areas of study in physics, and contains the most advanced topics in the course. As such this unit s coverage and depth of content has the potential to vary based on class understanding and time spent on other units. Unlike other units, the focus is on conceptual thinking as opposed to direct problem solving.

A formal report will be graded. In small groups, students will prepare a 5-10 minute presentation on an experiment, technology, or practical application that ties into the topics covered in class. Students will be evaluated on their understanding of their topic, and their communication of this knowledge. Students will complete several modern physics problems, and communicate the implications of several relativistic and quantum based concepts. POLICIES Contact information for parents: You may reach me at the school number, ext. 999 or using the blah@sb.ca. * is usually the quickest mode of communication. Extra Help: I am available for extra help one hour before school and one hour after school. Should my hours change I will make an announcement in class at least one day before. Students are welcome to make arrangements for tutoring at other times, such as lunch, if need be. EXPECTATIONS This is a Grade 12 University Preparation course so expectations are high as to prepare students for university. Students are expected to arrive on time with necessary materials, submit assignments by the due date as well as complete homework and readings in a timely manner. If students struggle with a concept, they are encouraged to take the initiative to get extra help before or after school. Late and Incomplete Assignments: Late assignments will receive a 5% deduction for every school day beyond the due date until the assignment is handed in, to a maximum of a 50 % reduction (two weeks late), unless otherwise negotiated with myself. Student s are expected to time manage effectively, and take responsibility for their due date organization. Incomplete or missed assignment/quizzes will receive a mark of zero unless an acceptable excuse is provided before - or immediately following in the case of absences - the expected submission date. Safety: Students must follow safety procedures as directed to assist in keeping the classroom safe during labs and activities. If students do not follow safety procedures after a reminder, they will not be allowed to complete the activity for the well-being of themselves and other students. Alternate arrangements will be made at the discretion of the teacher. Academic Honesty: Students are required to properly cite and reference all work that is not theirs. When completing individual assignments to be graded, copying is prohibited and detrimental to the learning objectives of the course. Students caught plagiarizing will dealt with seriously in accordance to school policy.
