The Lava Lamp – Density and Buoyancy


 Model Description This is a demonstration of the relationship between density and buoyancy.  It reinforces the concept that fluids that are less dense have a higher buoyancy.  In the case of the lava lamp, this causes the “lava” to rise vertically as heating causes its density to change.    This demonstration should take 3-5 minutes.

Fluid Properties


 Model Description This is a simple demonstration of the difference between density and viscosity in fluid mechanics.  Two equal size containers, one containing shampoo and the other corn syrup, are used to show the difference between the two concepts.  This demonstration should take 5-8 minutes. Engineering Principle Most students are familiar with density and viscosity […]
