GCSE science students need to understand that plant oils can be extracted by both crushing and pressing plant material and by the more complex process of steam distillation.
This resource describes a simple technique that can be run as a demonstration or as a class practical to extract a plant oil. There are also a couple of quick demonstrations based on plant oils and instructions for a student activity to show that nuts contain oils.
This resource can also be found on the SAPS website.
