Teaching science can often be a very tricky business: concepts, animals, bodily functions, and other difficult matters have to be explained in a more comprehensible manner. Whether it is a planetary system, a species of mammal, or a theory of light, models have always helped teachers to explain science to their students.
The Whipple Museum has a very large collection of teaching models; one recently-acquired model is a 19th-century anatomical model in papier-mâché.
