Density by University of Colorado 1.02

Discover the relationship between mass, volume and density by weighing and submerging various materials under water. Do objects like aluminum, Styrofoam, and wood float or sink? Can you identify all the mystery objects by weighing them and submerging them underwater to measure their volumes?<br /><br /> Sample Learning Goals<br /><br /> * Define and differentiate the concepts of weight, mass, volume and density.<br /> * Describe how the concept of density relates to an object's volume and mass.<br /> * Explain how objects of similar volume can have differing mass, and how objects of similar mass can have differing volume.<br /> * Explain why changing an object's volume or mass does not affect density (ie, understand density as a characteristic property).<br /> * Relate relative density to the volume-above-liquid-surface of a floating object.<br /> * Measure the volume of an object by observing the amount of fluid it displaces, and subsequently compute its density.<br /> * Identify an unknown material of arbitrary size by measuring its density (and comparing to a table of known densities).
