Each of the lessons has been designed to use approximately 4 hours of instructional time. The time is, of course, subject to change as per class participation and understanding and must also be considerate of such things as breaks.
Below is a sample of what one can expect in a lesson, complete with time expectations for each section.
The following are excerpts from:
Temperature - 30 minutes
§ Brief explanation on the freezing point of water.
§ Defining the terms; effective temperature and eutectic temperature.
§
Refer students to their manual
for a comparison of the five major anti-icing chemicals.
Chemical
Properties - 45 minutes
§ Discussion of the common features of deicing chemicals.
§ Review properties of chemicals in solution.
§ Discussion of terms such as melting capacity, concentration, solution solubility and specific gravity.
§ Introduction of a phase curve, referring back to the student lesson manual.
§ Summary of key features of the phase curve.
§
Establishing the originating data found on a phase curve for each
particular deicing chemical. Referring
to chart in Student Lesson Manual.
§ Introducing how to calculate a performance index and understand it’s relationship to melting capacity.
