![]() This engineering curriculum aligns to Next Generation Science Standards ( NGSS).Įngineers commonly design equipment or devices that requires them to take into consideration the viscosity of particular fluids. Ultimately, students gain an understanding of the concept of viscosity and its effect on flow rate. For example, heavy cream flows at a slower rate than skim milk. To identify the unknowns requires an understanding of the concept of viscosity. They examine control samples and unknown samples, which they must identify based on how fast they flow. They explore these properties in milk and cream, which are common fluids whose properties (and even taste!) differ based on fat content. Student groups conduct a brief experiment in which they quantify the flow rate to understand how it relates to a fluid's viscosity and ultimately chemical composition. Students study the physical properties of different fluids and investigate the relationship between the viscosities of liquid and how fast they flow through a confined area. ![]()
