In this activity, students explore these concepts. Students identify appropriate problems for technological design as they explore the science of viscosity. To extend the lesson to better meet this standard, students may design their own investigation of viscosity. Students conduct an investigation in measuring the viscosity of an oil sample at several temperatures.
Students use mathematics to calculate the density of several oil samples.
They graph viscosity versus temperature, and use their graph to determine what, if any, relationship exists between temperature and viscosity. A characteristic property of lubricants is viscosity, which is affected by temperature. Density is a property of all matter, and every substance has a characteristic density at a given temperature.
