In Science, we have just finished studying a unit called "Describing Matter."  The following concepts/topics were emphasized:

-Pure Substances/Elements

-Chemical Bonds

-Chemical Versus Physical Properties

-Compounds Versus Mixtures

-Atoms Versus Molecules

-Heterogeneous Versus Homogeneous Mixtures

Next, we will be starting a unit titled “Measuring Matter,” where we will concentrate on the following topics:

         -Weight versus Mass

          -Units of Mass and the International System of Units (SI)
