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.")
