Curated OER
Investigating the Effect Of Successive Heat and Cool Cycles on a Thermoplastic material.
Students investigate hot melt glue using a hot melt glue gun as an an injection molding simulator and a melt index viscometer. They evaluate the effect of heating and cooling by weighing the glue extruded over a constant time period.

A Comparison of Polymeric Liquids with Newtonian Liquids
Students concretely illustrate and define a macromolecule, observe the unique behavior of polymers and relate to their knowledge of molecules, and use the scientific process to determine the difference between Newtonian and non-Newtonian...
Curated OER
A Comparison of Polymeric Liquids with Newtonian Liquids
Students perform several tests on liquids. In this general science lesson, students compare the properties of polymeric and nonpolymeric liquids. They explain the composition and importance of macromolecules.

Serc: Fluid Viscosity
To give young scholars a feeling for both what viscosity values are and how they are measured in the lab, they measure fluid viscosity by dropping ball bearings into graduated cylinders of fluids.
