This experiment makes great demands on the students. The
saccharimeter model must not only be meticulously constructed, but
the measurements also require painstaking care. This is made even
more difficult by the requirement for complete darkness in the
physics laboratory.
The obvious solution is a division of labour. For example, the
class can be divided into two groups, which perform the
measurements with the single or double layer thickness,
respectively. Subsequently, the results can be exchanged and
recorded.
How does a saccharimeter work? To construct a model of a
saccharimeter and investigate how a sugar solution behaves when
polarised light is passed through it.
