• Calculate the density of a substance; use the density to calculate the mass or volume of a substance.
   

HOMEWORK ASSIGNMENTS

PLEASE CHECK THE CLASSROOM BOARD FOR THE DAILY HOMEWORK ASSIGNMENTS.  Since the pace of the class is decided daily based on the classes' understanding of the material, sometimes the class notes for a particular homework assignment are not gotten to. Therefore, the homework must be amended.
