Technical Writing, Part 3 of 4 (Safety and Assembly of Glider)


This lesson (3 of 4) includes safety or cautionary measures for the consumer or assembler. These same safety recommendations offer liability protection for the manufacturer. Students examine warnings/cautions/danger signage and create a unique cautionary sign for their balsa wood glider instructions.


Lesson #3 begins with an activity on the importance of safety. Students examine the safety/warning/cautionary components of instructions and create cautionary symbols with short captions for their instructions. Groups are assigned and the actual assembly of the glider takes place.

(Materials Note: A comprehensive list of materials can be found in Lesson no. 1 and below as a resource in the assignment "Let's Build This Thing.")
