Elasticity and viscosity. Help your class understand the similarities and differences with an introduction to viscous fluids. After describing four types of fluid behaviors: shear thinning, shear thickening, Bringham plastic, and Newtonian, pupils learn how to measure and calculate the viscosity of liquids.

Concepts

Instructional Ideas

• Divide the class into four groups and have them find fluids that exhibit one of the behaviors presented in the lesson
• Research as a class the types of fluids that biomedical engineers need to be concerned about while designing medical devices

Classroom Considerations

• The class should be familiar with elastic solids and how to calculate the modules of elasticity

Pros

• Includes a presentation to aid in the understanding of the material
• The the opening activity shows the association between the formula to calculate viscosity and Hooke's Law Equation 

Cons

• The plan does not present a clear, engaging instructional method
