How metals compare in density?
If you have some same size cubes of different metals, you will notice that some are much lighter than others. Lighter cubes are made of metals with lower density and heavier cubes are made of metals with higher density.
Low density metals are used in making airplanes.
 Project description
Density is one of the most important physical properties of any substance. Density varies among different metals and it can be used to identify pure metals from each other and from alloys. Obtain samples of different metals and test their density. Explain how you can identify pure gold from gold alloys by a density test.
