Density can be calculated by taking the mass of an object and dividing by the volume.  How can we apply density to the Medical profession?  Let’s look at bone density.  Bone density is found by using a certain type of x-ray machine.  It is calculated a bit differently and Cleveland Clinic has a brief article describing this test.  Discuss an application of density in the Medical profession.
