Students discover what viscosity is and how it relates to our lives. They drop marbles into large containers of liquids and time how long it takes the marbles to travel to the bottom. They time five marbles and compute an average time.

Understanding Viscosity through Investigation and Comparison of Fluids
Not all liquids are the same. Investigate the viscosity of different fluids with a series of activities designed for eighth grade science. As learners move through learning centers with different experiment setups, they determine the...

Lab: Successive Heat and Cool Cycles in Thermoplastic Polymers
Do the properties of a thermoplastic polymer change after successive cycles of heating and cooling? In this lab assignment, young chemists find out by melting, molding, and re-melting hot glue gun sticks one, two, and three times. They...

Density Rainbow and the Great Viscosity Race
Students explore the densities and viscosities of fluids as they create a colorful 'rainbow' using household liquids. While letting the fluids in the rainbow settle, students conduct 'The Great Viscosity Race,' another short experiment...
