Separating Mixtures and Forming
Solutions SC.5.P.8.2 and SC.5.P.8.3
Demonstrate and explain that mixtures of solids
can be separated based on observable properties
of their parts such as particle size, shape,
color, and magnetic attraction. Investigate and
identify materials that will dissolve in water
and those that will not and identify the
conditions that will speed up or slow down the
dissolving process.

combined, but together they do not form a new
substance. They can be easily separated.
