Chemistry HL

Part of the IB subject group 4, Sciences, the Chemistry HL course combines academic study with the acquisition of practical and investigational skills.

Themes covered through the course

The first year of the course covers stoichiometry, periodicity, bonding, energetics, kinetics and equilibrium. The second year covers acids/bases, redox processes, organic chemistry, measurement and analysis, and biochemistry. 

Activities and assessment

Students will undertake a variety of activities in the Chemistry course, ranging from classroom based discussions and group work to online interactives, formative assignments, wiki/collaborative activities and journals. Students are assessed through a single individual investigation as well as three written papers. The investigation may involve a hands-on approach, use of databases, modelling, simulation or a hybrid. Student work is internally assessed by the teacher and externally moderated by the IB.

Advice from our teachers

In order to succeed in Chemistry HL, we recommend students commit four hours per week. How much of the course material is covered in the classroom and how much via independent learning is flexible and to be decided by the school teacher.

Benefits to students

Taking Chemistry HL will enable students to:

  • gain an understanding of the chemical principles underpinning both the physical environment in which we live and all biological systems
  • develop their observational, analytical and collaborative skills
  • consume course content outside of the classroom, including formative exercises and interactive activities
  • become independent learners and develop time-management skills
  • experience a wide range of online learning tools
