IB Chemistry SL

(2-year course)


Grades: 11–12 (two-year course)

Subject Area/Course Credit: Science, 1 credit each year

Prerequisite: C or above in Coordinated Science II, or C- or above in AP Physics 1, or science teacher recommendation

IB Chemistry SL is a two-year course designed to prepare students for the IB exam at the end of the second year.

As one of the three natural sciences in the IB Diploma Programme, chemistry is primarily concerned with identifying patterns that help to explain matter at the microscopic level. This then allows matter’s behaviour to be predicted and controlled at a macroscopic level. The subject therefore emphasizes the development of representative models and explanatory theories, both of which rely heavily on creative but rational thinking. DP chemistry enables students to constructively engage with topical scientific issues. Students examine scientific knowledge claims in a real-world context, fostering interest and curiosity. By exploring the subject, they develop understandings, skills and techniques which can be applied across their studies and beyond. Integral to the student experience of the DP chemistry course is the learning that takes place through scientific inquiry both in the classroom and the laboratory.
