At the end of this unit, you will be able to:

1. Define mass as the measure of atomic “stuff”; contrast with volume - the amount of space an object occupies.

2. Develop, from experimental evidence, the law of conservation of system mass.

3. I can measure using scientific glassware.

4. I can calculate with significant figures (sig figs).

5. Use density as a conversion factor between mass and volume; apply this to quantitative problems.

6. Given a graph of mass vs. volume of a various substances, relate the slope to the density of the substances.

7. Recognize that density is a characteristic property of matter (i.e., it can be used to help identify an unknown substance).
