Science Sampler: Node graph visualizations for eighth-grade mathematics students using a virus transmission simulation

Science Scope—Summer 2008

Because eighth-grade curriculum standards focus in part on systems analysis and graphing, a lesson was created to enhance students’ analytical skills with the introduction of a type of graph, the node graph, which can be used to represent the interconnectedness of system components. This lesson is rooted in understanding real-world concepts regarding the transmission of infectious agents throughout a population.
