IB physicists are required to complete 40 (SL) or 60 (HL) hours of practical work as part of their course.
|Section of course||Number of hours (approx.)|
|Recommended practicals||15 SL / 20 HL|
|Group 4 Project||10|
|Additional classtime practicals||5 SL / 20 HL|
Some schools will ask you to maintain a lab book logging all required and additional classtime practicals to develop towards the Investigation marking criteria.
Use this as a revision checklist for the apparatus, methods and analytical techniques that you should know for the exam.
