Chemistry (group 4)

Chemistry is an experimental science that combines academic study with the acquisition of practical and investigational skills. It is often called the central science as chemical principles underpin both the physical environment in which we live and all biological systems. Apart from being a subject worthy of study in its own right, chemistry is often a prerequisite for many other courses in higher education, such as medicine, biological science and environmental science.  The skills learnt in chemistry will also open up applications to a vast range of other courses.  

Through studying a science subject, students should become aware of how scientists work and communicate with each other. While the scientific method may take on a wide variety of forms, the emphasis on a practical approach. In addition, through the overarching theme of the “Nature of Science” this knowledge and skills will be put into the context of the way science and scientists work in the 21st century and the ethical debates and limitations of creative scientific endeavour.

The sciences are taught practically. Students have opportunities to design investigations, collect data, develop manipulative skills, analyse results, collaborate with peers and evaluate and communicate their findings. The investigations may be laboratory based or they may make use of simulations and data bases. Students develop the skills to work independently on their own design, but also collegiately, including collaboration with schools in different regions, to mirror the way in which scientific research is conducted in the wider community.

Aims
  • Provide opportunities for scientific study and creativity within a global context that will stimulate challenge students 
  • Provide a body of knowledge, methods and techniques that characterize science and technology
  • Enable students to apply and use a body of knowledge, methods and techniques that characterize science and technology
  • Develop an ability to analyse, evaluate and synthesize scientific information 
  • Develop experimental and investigative scientific skills
  • Engender an awareness of the need for, and the value of, effective collaboration and communication during scientific activities 
  • Develop and apply the students’ information and communication technology skills in the study of science
  • Raise awareness of the moral, ethical, social, economic and environmental implications of using science and technology
  • Develop an appreciation of the possibilities and limitations associated with science and scientists 
  • Encourage an understanding of the relationships between scientific disciplines and the overarching nature of the scientific method

 

Syllabus and Assessment

At both higher and standard level 80 % of the final grade is based upon examinations with 20 % on Internal Assessment. The IB Chemistry exam is made up of three parts for both SL and HL – two external exams and one internal assessment. 

SL

Paper 1  (1 hour and 30 minutes – 36%)
Paper 1A: Multiple-choice questions
Paper 1B: Data-based questions
(Total 55 marks)

Paper 2  (1 hour and 30 minutes – 44%)
Short-answer and extended-response questions
(Total 50 marks)

Internal Assessment (10 hours – 20 %)
The internal assessment consists of one task: the scientific investigation.
This component is internally assessed by the teacher and externally moderated by the IB at the end of the course.
(Total 24 marks)

 

HL

Paper 1 (2 hours – 36%)
Paper 1A: Multiple-choice questions
Paper 1B: Data-based questions
