Special clothing is worn by "community helpers" such as police officers, nurses, firefighters, cafeteria workers, dentists, and waste management workers as they do their jobs. The special clothing allows workers to be safe. Therefore, exploring how hats help community workers do their jobs can be a way to introduce the idea of how the shape or form of an object is related to how it functions. The objective of this month's lesson is to explore the relation between a hat's structure and function. (Contains 1 figure and 1 resource.)
