As part of the engineering design process to create testable model heart valves, students learn about the forces at play in the human body to open and close aortic valves. They learn about blood flow forces, elasticity, stress, strain, valve structure and tissue properties, and Young's modulus, including laminar and oscillatory flow, stress vs. strain relationship and how to calculate Young's modulus. They complete some practice problems that use the equations learned in the lesson mathematical functions that relate to the functioning of the human heart. With this understanding, students are ready for the associated activity, during which they research and test materials and incorporate the most suitable to design, build and test their own prototype model heart valves.
With Fire & Sword is the thrilling sequel to the action role-playing hit Mount & Blade: Warband. Be a mercenary or join one of the five battling factions to conquer, destroy or create empires. In an open sand box world you choose your allies, your enemies, what provinces to conquer, what castles to siege and what quests to embark on.With Fire & Sword also greatly builds and expands upon the highly regarded combat system from Mount & Blade: Warband.
