Using the NGSS in your FACS Classroom Trudy Swain tswain@nsd.org Course Objectives • Leave with resources to enhance your FACS unit planning • Experience a lab using the NGSS • Become familiar with the NGSS as a 3 dimensional teaching model
Viscosity Lab Don’t start here. We often telegraph the outcome of a lab. We start the class by telling our students. ‘Today we are making Tuna Niçoise.’ ‘These are the steps.’ ‘Any questions?’ ‘Now go make your salad, and follow all the kitchen safety rules I’ve taught you.’

Splat test To conduct a splat test • Pour 5 ml ingredient onto the center of the target • measure diameter of ingredient spread Why do some liquids pour more easily than others? What is another way we could test the viscosity of an ingredient?
Identifying the Scientific Phenomena in a lab The _________ the viscosity value, the ___________ flow rate. What makes for the perfect flavor and mouthfeel of a salad dressing?
Reflections on viscosity Viscosity: Is a quantity that describes a fluid’s resistance to flow. This resistance is caused by the intermolecular attraction of the molecules making up the liquid. You can think of viscosity as the thickness of a fluid. • Why would viscosity be important to Food Scientists? • How would viscosity effect the flow of foods through an esophagus? • If you test a substance with low viscosity, what would you expect the flow rate to be, or the splatter diameter?
