Making a model is different than reading or listening to a teacher, it's another way of learning. It allows one to learn using their own initiative and creativity. Modeling uses hand motor skills to connect motion and materials with concepts. It is not a fast cognitive implant of information, but a slow laborious meditative activity. However, it seems to obey the law of the harvest, you reap what you sow. In this case, the labor produces a deeper understanding and experience of the flower's anatomy.
