- Define mass as the measure of atomic “stuff”; contrast with volume – the amount of space an object occupies.
- Use a multiple beam or double-pan balance to determine the mass of various objects.
- Record the value of an object’s mass in a manner consistent with the limit of precision of the balance.
- Represent class data using a histogram; use the histogram to interpret trends in the data.
- Develop, from experimental evidence, the law of conservation of system mass.
- Relate the volume of a container (in cm3) to the volume of liquid it contains (in mL).
- Recognize that instruments have a limit to their precision; relate the data recorded to the quality of the measurement.
- Given a graph of mass vs. volume of a various substances, relate the slope to the density of the substances.
- Recognize that density is a characteristic property of matter (i.e., it can be used to help identify an unknown substance).
- Use density as a conversion factor between mass and volume; apply this to quantitative problems.
- Use differences in density of solids, liquids and gases as evidence for differences in the structure of matter in these phases.
