Density and Graphing

This lesson involves students calculating the density of various objects of differing sizes of the same substance. Each student group will need a balance, a ruler, and/or a graduated cylinder. They use their collected data to create a graph showing the relationship between mass and volume. The slope of the line created will be the density of the substance, which is consistent for all different volumes or masses so long as the substance stays the same. They will use their knowledge of density and graphing to suggest the solution to an imaginary problem in which a student wants to know if the bike they ordered is made of aluminum as it is supposed to be.
