IB+Chemistry


 * IB HIGHER AND STANDARD LEVEL CHEMISTRY**


 * Introduction**
 * Introduction**

To study Chemistry is to study the materials the world is made from and the way new materials can be produced. Understanding Chemistry is an important part of understanding the world around us. It helps us to understand how to make better materials, how to get the energy we need and how to protect the environment. At university, Chemistry is needed for the study of chemistry, medicine, pharmacy, biochemistry, food science, biotechnology and environmental sciences.


 * Course Outline**
 * Course Outline**

IB Chemistry can be studied at either higher or Standard level at Patana. The Higher level course requires 240 hours of study (three double periods per week), whilst the Standard level course requires 150 hours (two double periods per week). Both Higher and Standard level courses consist of two components, theory and internal assessment (practical work).

 * CORE and AHL**

There are eleven topics studied in the CORE theory syllabus and, at Higher level, these are extended in the Additional Higher level material (AHL). The eleven topics are Quantitative Chemistry, Atomic Structure, Periodicity, Bonding, Energetics, Kinetics, Equilibrium, Acids and Bases, Oxidation and Reduction, Organic Chemistry and Measurement and Data Processing.


 * OPTIONS**

Both Higher level and Standard level students study two options. At Standard level the duration of each option is 15 hours, whilst at Higher level the duration is 22 hours.

At Patana the options studied are selected from:

· Modern Analytical Chemistry · Human Biochemistry · Chemistry in Industry and Technology · Medicines and Drugs · Environmental Chemistry · Food Chemistry · Further Organic Chemistry


 * Assessment**
 * Assessment**

Assessment has two components: internal assessment and external assessment. The percentage contribution for each component to the final IB Chemistry course mark is as follows:

· Internal assessment 24% · External assessment 76%

Internal assessment falls into the general category of practical work, but is designed to be flexible in both content and structure. Students should expect to carry out both short term and long term investigations in addition to the Group 4 project.

Patana report levels are formulated from end of unit test percentages and practical work in a similar way to the final IB Chemistry papers. In the past students have found both higher and Standard level Chemistry courses quite challenging and numbers of students electing to take these courses have necessitated both Standard level and Higher level students being taught together.

External assessment consists of three written papers at both Higher and Standard level. Details of the external assessment are summarised in the table below:
