Teaching notes:
- The slide only gives a rough outline of the lesson.
No effort has been made to discuss concrete questions and exercises,
types of
instruction or multi-media.
- This "Discover Silicones Documentation" contains factual information, experiments, worksheets, videos and animations for this
module.
- The module as described above is suitable for students in
sixth form. If you confine yourself to the concepts of "hydrophilic" and "water
repellent" and dispense with the detailed explanations
at the particle level, the module may also be adapted for first
lessons in lower forms.
- After block "4. Explanation of experimental
results", there
are various ways in which the subject matter can be extended,
dealt with in more detail, and applied. For example, a) Further
properties
and applications of silicone fluids, e.g. as antifoam agents,
b) Manufacture of silicone fluids or c) More detailed comparison
of
linear silicone macromolecules and polyolefin macromolecules.
These may be covered during lessons, given as homework or set
up as part
of a project.
- This module may be used as a constructivist learning
cycle based on the concept of didactic integration of subject
systematics
and realistic contexts. Details on didactic integration
are to be found
under http://www.chemiedidaktik.uni-wuppertal.de/ and in Ref.
[8].
