Jigsaw puzzles use strategies that develop problem-solving skills and boost logical reasoning. People complete jigsaw puzzles individually and in groups. In groups, cooperative learning is used to help each other solve the puzzle and build comprehension. Individually, cooperative learning helps build critical thinking. Online, it is difficult to solve the puzzle and build comprehension; however, we will each take a piece of the jigsaw puzzle below and discuss the following questions: 
which component of the fire sprinkler is your selected puzzle piece;
when does that component activate; and

where, why, or how is the component used?
Finish with discussing if you have ever seen a sprinkler head activated. If so, where? Did it control or extinguish the fire?
