The internal assessment aspect of the course involves three principle elements:
1) The attainment of laboratory skills in the completion of either 40 or 60 hours of time involved in a practical scheme of work. This is a requirement of the course, although no grades will be submitted.
2) The Group 4 project, which will involve collaboration with other group 4 subjects (the sciences and mathematics).
3) The IA Individual Investigation, which is worth 20% of the over all grade.
The IA Individual investigation dominates the landscape of the new IB criteria, and a comprehensive guide can be downloaded from the link below.
