Review density definition and density formula. Discuss density in terms of molecule arrangement in a substance.
Develop how to solve the following problem: A solid substance measures a mass of 13.5 grams. A measure of the length, width, and height product indicates a volume of 5 cubic centimeters. Determine the volume and indicate the proper units. Use a table of density values for elements and determine what the element is. Solve a related problem with a given mass and volume. Is the second substance the same element as the first? Determine the density and element density table. Discuss how to measure the density of an irregular shaped object by using water displacement method. Conclude that an object will displace a volume of water equal to the volume of the solid. Work a problem to explain the procedure.
