Description

Different mixtures of solids are supplied, along with
the means of applying five standard methods of
separation: flotation, magnetic separation, solution
and recrystallization, melting and resolidification,
and shifting to give students a solid base in mixture
analysis. They are challenged to examine a solid to
determine which separation technique to use. If the
first technique fails, they try again, and so on, until
they succeed. You will receive enough materials for 30
students and instructions. A heat source, required, is
available separately.
