IB Physics Exam Format 2023

In 2023, the International Baccalaureate (IB) Physics exam format will undergo changes to provide students with a more comprehensive assessment of their knowledge and skills. The new exam format consists of two examination papers for each level, both of which must be attempted by students. The time allocated for the external examination papers remains the same, with three hours for Standard Level (SL) and 4.5 hours for Higher Level (HL).

During the exam, students are allowed to use a calculator for all of Paper 1, including the multiple-choice questions and Section B. This allows students to effectively apply their mathematical skills in solving physics problems. Additionally, there is a reading time of five minutes provided at the beginning of the exam, allowing students to familiarize themselves with the questions before starting.

One significant change in the 2023 IB Physics exam format is the availability of the data booklet during the exam. Students will have access to the data booklet, which contains relevant formulae, constants, and other useful information. This allows students to focus on applying their knowledge and understanding of physics concepts without the need to memorize specific formulas and values.

Exam Level	Examination Papers	Time Allocation	Additional Features
Standard Level (SL)	2 papers	3 hours	Calculator allowed for Paper 1 and reading time of 5 minutes
Higher Level (HL)	2 papers	4.5 hours	Calculator allowed for Paper 1 and reading time of 5 minutes

IB Physics Internal Assessment Criteria 2023

The internal assessment (IA) in the new IB Physics syllabus has undergone significant changes. The IA is now called “the scientific investigation” and counts for 20% of the overall assessment. The allocated time and word count for the IA remain unchanged. The assessment criteria have also been revised, with equal weighting given to four criteria: research design, data analysis, conclusion, and evaluation.

In the scientific investigation, students are expected to demonstrate their ability to plan and carry out a scientific inquiry, analyze data, draw relevant conclusions, and evaluate the limitations and implications of their investigation. The research design criterion evaluates the student’s ability to formulate clear research questions, plan and design a method for data collection, and consider ethical guidelines. The data analysis criterion assesses the student’s ability to organize and analyze data using appropriate mathematical and statistical techniques. The conclusion criterion focuses on the student’s ability to draw valid conclusions based on their data analysis and evaluate the reliability of those conclusions.

The evaluation criterion assesses the student’s ability to evaluate the limitations of their investigation, propose improvements, and consider the implications of their findings. To meet the assessment criteria, students should clearly document their research process, including any modifications they made to their initial plan, and provide a clear and logical analysis of their data. The scientific investigation allows students to develop their scientific skills and engage in independent research, fostering a deeper understanding of the scientific method and the process of inquiry.

IB Physics Practical Scheme of Work

The practical scheme of work (PSOW) is an integral part of the IB Physics curriculum. It provides students with hands-on experience and opportunities to apply theoretical concepts in real-world settings. The PSOW aims to develop students’ practical skills, enhance their understanding of scientific inquiry, and foster their ability to think critically and solve problems.

The IB Physics PSOW consists of a series of experiments and investigations that cover a wide range of topics across the physics syllabus. These practical activities are designed to enable students to explore and manipulate variables, collect and analyze data, and draw conclusions based on their findings. Through the PSOW, students develop essential laboratory skills, such as using various measurement instruments, conducting controlled experiments, and ensuring accuracy and precision in their observations.

The PSOW also encourages collaboration and teamwork among students. It often involves group experiments where students work together to design and execute investigations, share responsibilities, and communicate their findings. This fosters a cooperative learning environment and promotes the development of interpersonal skills, such as effective communication, cooperation, and leadership.

Example Experiment: Determining the Acceleration due to Gravity

One example of a practical activity found in the IB Physics PSOW is the experiment to determine the acceleration due to gravity. In this experiment, students use a simple pendulum and measure the period of oscillation for various lengths of the pendulum string. By analyzing the relationship between the length of the string and the period of oscillation, students can calculate the acceleration due to gravity.

This experiment not only reinforces the concept of gravity but also allows students to practice important skills such as data collection, data analysis, and error propagation. It also provides an opportunity for students to critically evaluate their results and consider potential sources of error and improvements that can be made to the experimental setup.

Length of Pendulum String (cm)	Period of Oscillation (s)
10	0.84
20	1.19
30	1.47
40	1.70
50	1.90

In this experiment, students would record the length of the pendulum string and the corresponding period of oscillation. They would then plot a graph of period squared against the length of the string and determine the slope of the line, which represents the acceleration due to gravity.

The IB Physics PSOW provides students with valuable hands-on experiences that complement their theoretical understanding of physics. Through a variety of practical activities, students develop essential laboratory skills, enhance their scientific inquiry abilities, and gain a deeper appreciation for the principles of physics.
