This lesson focuses on the following Three Dimensional Learning aspects of NGSS:Ĭommunicate scientific and technical information (e.g. Communicate scientific information about why the molecular-level structure is important in the functioning of designed materials.Ĭommunicate scientific and technical information about why the molecular-level structure is important in the functioning of designed materials.Ĭlick to view other curriculum aligned to this Performance Expectation. ![]() Demonstrate an understanding of how engineers measure and calculate fluid material properties such as viscosity.Explain four different types of fluid behavior: Newtonian, shear thinning, shear thickening, and Bingham plastic.Describe the similarities and differences between elastic solids and viscous fluids.Understanding fluid behavior can help engineers to select the best fluid to operate in a device or to design devices that are able to efficiently and harmlessly operate in environments that contain fluids.Īfter this lesson, students should be able to: Thus, it is important for engineers to understand how fluids behave under various conditions. This engineering curriculum aligns to Next Generation Science Standards ( NGSS).Įngineers often design devices that transport fluids, use fluids for lubrication, or operate in environments that contain fluids, such as engines, printers and pacemakers. In addition, fluid material properties such as viscosity are introduced, along with the methods that engineers use to determine those physical properties. ![]() Several types of fluid behaviors are described-Bingham plastic, Newtonian, shear thinning and shear thickening-along with their respective shear stress vs. Hungry for some science, but you don’t have time for a full-course research plate? Then check out USGS Science Snippets, our snack-sized science series that focuses on the fun, weird, and fascinating stories of USGS science.Students are introduced to the similarities and differences in the behaviors of elastic solids and viscous fluids. Next EarthWord: Our next word sounds like what the British might call an outhouse. ![]() In determining what types of oil and gas are present, as well as how much is technically recoverable, viscosity of the petroleum is very important. Finally, viscosity is also a factor in our oil and gas research.Next, in our water studies, the viscosity of both surface water and groundwater can affect all manner of things, from how fast a river flows to how deep groundwater can percolate.First, when studying the flow of lava and its effects, the viscosity of the flow can affect the speed at which the lava travels. Viscosity factors into USGS science in a number of ways.It affects how these liquids behave, and can change depending on such factors as temperature and pressure. Viscosity is an important measurement in most studies of fluids, from water to oil.Use/Significance in the Earth Science Community: ![]()
