 Unit 1 - Physical Properties of MatterInstructional Goals1.  Define mass and volume. Compare and contrast mass and volume2.  Demonstrate proper use of measurement devices, and record the value of an object's mass and dimensions in a manner consistent with the limit of precision of the tool being used to measure. Online Practice #1  Online Practice #2  Online Practice #4 3.  Represent data using a histogram.4.  Use a histogram to interpret trends in data.5.  Develop, from experimental evidence, the law of conservation of mass. Online Practice  6.  Relate the volume of a container (in cm3) to the volume of liquid it contains (mL).7.  Recognize that instruments have a limit to their precision.  Relate the data recorded to the quality of the measurement8.  Given a graph of mass vs. volume of various substances, relate the slope to the density of the substance.Online Practice  9.  Recognize that density is a characteristic property of mater.10.  Use density as a quantitative conversion factor between mass and volume.11.  Use differences in density fo solids, liquids, and gases as evidence for differences in the structure of matter in these phases.  TutorialsUnderstanding Conversion Factors Dimensional Analysis (Conversions!) Denisty!
