Metal Density Cube Set, Economy Choice
AP6489
Reduce your density lab costs with this economical set of four metal cubes. Students measure the densities of the four metal blocks and then determine their composition. This simple kit is effective at teaching density and is a great value! One-inch ...

Density Rod
AP4632
Simple device with a multitude of demonstration possibilities. The rod responds to changes in density of a liquid by sinking or rising in the liquid. As the density of the liquid is changed, the rod moves up or down accordingly. It sinks in warm wate...

Reverse Density Rod
AP6069
The “normal” density rod (AP4632) sinks in warm water and floats in cold water. The reverse density rod works just the opposite! It will float in water 30-35 ºC and sink in cool water! Using both rods will enhance your ability to make den...

Density of Solids Kit
AP4615
A gallon of milk seems to weigh more than the fluffy pillow you sleep on. You probably wouldn't confuse these two materials nor have trouble thinking about their density. But how about steel versus iron? Aluminum versus tin? Density is a very measura...
