To help them understand the 3-dimensional nature of molecules and how they may react/combine.
What happens to the molecules of a solid such as a sugar cube when it dissolves water?
The sugar molecules dissipate throughout the water - mixing with the water molecules.
Substance changes from solid to liquid?
This physical phenomenon (a change of phase) is called melting; during melting the chemical nature of molecules is not changed but the bonds between molecules are weakened.

What is the result of a dead star collapsing in on itself due to the strong gravity?
A lot of scientists consider this phenomenon to be the origin of Black Holes, which result in a gravity point so dense that it will suck in anything within it's range and crush it into it's component molecules.
