After learning how to define networks in lesson 1, and how to analyze a network in lesson 2, students were tasked with constructing a network in lesson 3.  Students worked in groups of up to four people to construct an economic network, with each student contributing at least 5 nodes and 5 edges.  The ability to understand how networks function, and how to analyze and construct a network will be valuable skills as we move forward in the unit and investigate human body systems, ecosystems, and the integration of the emerging cryptocurrency economy with our study of ecosystems.
