IB PHYSICS

COURSE SYLLABUS

2012 - 2013

THE IB LEARNER PROFILE

A BRIEF INTRODUCTION

Welcome to the wonderful world of physics! It’s pretty much the greatest thing ever. Physics is the study of everything.

Physicists want to understand how everything in the universe works, so there are many different branches of physics.

These topics may seem unrelated, but scientists believe that they are really all the same, and they hope to prove it in the

future. In this course, you will get a taste of most of these different topics. Students doing Higher Level (HL) and

Standard Level (SL) will get to study together, but the HL students will get to study a few extra topics, and will study a

few others in more detail. Here is a list of topics that will be covered in this course:

THE CORE – These are the main topics that HL and SL students will study together.

Topic 1: Physics and Physical Measurement

Topic 2: Mechanics

Topic 3: Thermal Physics

Topic 4: Oscillations and Waves

Topic 5: Electric Currents

Topic 6: Fields and Forces

Topic 7: Atomic and Nuclear Physics

Topic 8: Energy, Power and Climate Change

AHL – These are additional topics that will only be covered in the HL course.

Topic 9: Motion in Fields

Topic 10: Thermal Physics

Topic 11: Wave Phenomena

Topic 12: Electromagnetic Induction

Topic 13: Quantum Physics and Nuclear Physics

Topic 14: Digital Technology

OPTIONS – Both students in SL and HL are required to study two additional topics, called options. Some of them are for

only HL, some for only SL, and some are shared.

SL ONLY:

Option A: Sight and Wave Phenomena

Option B: Quantum Physics and Nuclear Physics

Option C: Digital Technology

Option D: Relativity and Particle physics

In this course, we will be studying Option A, Sight and Wave Phenomena. The content of this option is actually

the same as topic 11, so SL and HL students can actually study this topic together, but for HL students, it will not

count as an option.

HL AND SL:

Option E: Astrophysics

Option F: Communications

Option G: Electromagnetic Waves

In this course, we will be studying Option E, Astrophysics. This will count as the second option for SL, and the

first option for HL. HL students will be studying a few hours of additional material.

HL ONLY:

Option H: Relativity

Option I: Medical Physics

Option J: Particle Physics

In this course, we will be studying either Option H or Option I. Only HL students will be studying one of these

options.

AIMS AND OBJECTIVES OF IB PHYSICS

AIMS – These are the goals of IB physics. They are the things that this course will do for you. The aims of IB physics are

to…

1. provide opportunities for scientific study and creativity within a global context that will stimulate and challenge students

IB ASSESSMENT

The IB will assess your abilities, and give you a final grade at the end of the program. This grade is on a number scale,

from 0 to 7. A 7 is the highest grade you can achieve.

This grade comes from your External Assessment (your IB exam) and your internal assessment (practical work).

EXTERNAL ASSESSMENT – 76%

Your exam will be in November 2013. This one exam counts for most of your grade, so clearly, it is very important. You

will receive a score on this exam from 0 to 7. It consists of three papers, or three separate tests. It is different for SL and

HL students:

INTERNAL ASSESSMENT – 24%

The practical work (experiments) you do in class will make up the internal assessment. SL students will need to do about

45 hours of practical work during the course, and HL students will do about 65 hours. A list of all the practical work that

you do, called the Practical Scheme of Work (PSOW), will be compiled and sent to the IB during your last semester.

Some of the practical work you do will require you to write a formal lab report. Lab reports will be graded using the IB

criteria and aspects:

DESIGN(D)

Levels/marks Aspect 1 Aspect 2 Aspect 3

Defining the problem and

selecting variables Controlling variables

Developing a method for collection of data

Complete/2 Formulates a focused problem/research question and identifies the relevant variables.

Designs a method for the effective control of the variables.

Develops a method that allows for the collection of sufficient relevant data.

Partial/1

Formulates a problem/research question that is incomplete or identifies only some relevant variables.

Develops a method that allows for the collection of insufficient relevant data.

Not at all/0

Does not identify a problem/research question and does not identify any relevant variables.

Designs a method that does not control the variables.

Develops a method that does not allow for any relevant data to be collected.

DATA COLLECTION AND PROCESSING(DCP)

Levels/marks Aspect 1 Aspect 2 Aspect 3

Recording raw data Processing raw data Presenting processed data

Complete/2

Records appropriate quantitative and associated qualitative raw data, including units and uncertainties where relevant.

Processes the quantitative raw data correctly.

Presents processed data appropriately and, where relevant, includes errors and uncertainties.

Partial/1

Records appropriate quantitative and associated qualitative raw data, but with some mistakes or omissions.

Processes quantitative raw data, but with some mistakes and/or omissions.

Presents processed data appropriately, but with some mistakes and/or omissions.

Not at all/0

Does not record any appropriate quantitative raw data or raw data is incomprehensible.

No processing of quantitative raw data is carried out or major mistakes are made in processing.

Presents processed data inappropriately or incomprehensibly.

CONCLUSION AND EVALUATION(CE)

Levels/marks Aspect 1 Aspect 2 Aspect 3

Concluding Evaluating procedure Improving the investigation

Complete/2

States a conclusion, with justification, based on a reasonable interpretation of the data.

Evaluates weaknesses and limitations.

Suggests realistic improvements in respect of identified weaknesses and limitations.

Partial/1 States a conclusion based on a reasonable interpretation of the data.

Identifies some weaknesses and limitations, but the evaluation is weak or missing.

Suggests only superficial improvements.

Not at all/0

States no conclusion or the conclusion is based on an unreasonable interpretation of the data.

Identifies irrelevant weaknesses and limitations.

Suggests unrealistic improvements.

Some lab reports will only be assessed for one or two of the criteria, and some will be assessed on all three. Since the

maximum score for each aspect is 2, the maximum score for each of the criteria is 6. The IB will accept the two highest

scores in each of the criteria.

THE GROUP 4 PROJECT:

This is a large research project that all IB science students perform together. Students will decide on a topic, plan and

execute an experiment, and write a lab report together. This project represents 10 hours of your PSOW. You will learn

the details about this project later. There is a fourth criterion that will be assessed only during the group 4 project,

called Personal Skills (PS). This criterion, like the others, has a maximum score of 6.

MANIPULATIVE SKILLS(MS) (Assessed summatively)

Levels/marks Aspect 1 Aspect 2 Aspect 3

Following Instructions Carrying out techniques Working Safely

Complete/2

Follows instructions accurately, adapting to new circumstances (seeking assistance when required).

Competent and methodical in the use of a range of techniques and equipment.

Pays attention to safety issues.

Partial/1 Follows instructions but requires assistance.

Usually competent and methodical in the use of a range of techniques and equipment.

Usually pays attention to safety issues.

Not at all/0 Rarely follows instructions or requires constant supervision.

Rarely competent and methodical in the use of a range of techniques and equipment.

Rarely pays attention to safety issues.

Your score for this criterion will be based on all of the practical work you do during the course. You can receive a

maximum score of 6 points.

So, your score for internal assessment will be based on these 5 criteria:

D 6 x 2 = 12

DCP 6 x 2 = 12

CE 6 x 2 = 12

PS 6 x 1 = 6

MS 6 x 1 = 6

This gives a total of 48 points for internal assessment.

ICT: This is the final requirement for internal assessment. ICT refers to the use of technology when doing experiments.

There are five software applications that must be used:

1. Data logging in an experiment

2. Software for graph plotting.

3. A spreadsheet for data processing.

4. A database.

5. Computer modeling/simulation.

We will use each of these applications at least once during the course.

In addition to your IB assessment, you will also receive grades for this course. A grade report will be sent home four

times a year. Your grades will be determined as follows:

Mid-term Exam ……… 25%

Final Exam ……………… 25%

In-class Tests …………. 15%

Homework …………….. 15%

Lab Work ………………. 15%

Class Participation …. 5%
