"Students will build a lung model to learn how their lungs and diaphragm work to make them breathe. The lesson features a demonstration on how incomplete combustion of fossil fuels releases particles into the air that can negatively affect human health, and how we can protect ourselves from these effects."
"Lesson from TeachEngineering.org. Contributed by the Techtronics Program, Pratt School of Engineering, Duke University.
Note: This activity, part of a teachengineering curricular unit on Engineering and the Human Body that includes a lesson on the heart, could be enhanced with two preliminary heart-valve activities - Engineering the Heart and Saving a Life: Valve replacement"
"Graphs are a useful tool in science. The visual characteristics of a graph make trends in data easy to see. One of the most valuable uses for graphs is to "predict" data that is not measured on the graph.
