The study of the human form is fundamental to both science and art curricula. For vertebrates, perhaps no feature is more important than the skeleton to determine observable form and function. As Leonard da Vinci’s famous Proportions of the Human Figure (Virtruvian Man) illustrates, the size, shape, and proportions of the human body are defined by bones and their articulations. In this unit that focuses on the human skeleton, students are introduced to these concepts by asking them both to study da Vinci’s drawing and build their own model of the human skeleton. Units on animal camouflage and architecture are also presented to further support the art and science connection.
