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.
