Interfaces between body systems - 7th grade science
7th graders used 2D images to create 3D models of the microscopic interfaces between body systems, especially respiratory and circulatory (alveoli of the lungs) and digestive and circulatory (villi of the small intestine)Education

Microscopic features of human anatomy, like alveoli and villi, are challenging for young learners to engage with. Their visualization tools - microscopes - are not powerful enough to view these tiny structures directly, and 2D images in textbooks or online cannot convey the details of these structures. In this 7th grade class, students created their own 3D models of these interfaces between body systems to show features like immense surface area and the proximity of circulatory system capillaries that supports diffusion from one system to another.
