Elastic, Plastic and Everything in Between: Material Properties Explained


The lesson plan will serve to introduce a few of the material physical properties – Elasticity, Plasticity, and Visco-elasticity that play a crucial role in engineering. Basic concepts of elasticity and plasticity are introduced with the help of an elastic cord and a Pull-N-Pak plastic. In addition, bouncy ball, Silly Putty and Play Doh are used to demonstrate and illustrate the properties of elasticity, visco-elasticity and plasticity, respectively.
