What does a solid look like at the atomic scale?
Where have the atoms traveled?
As each model runs, follow one particle for a time. Repeat for different particles.

Here are models of three solids.
</p>
<p>
One is a solid of atoms, one is a solid of water molecules (ice), and
one is a mix of atoms and molecules.
</p>
<p>
Run the models and watch them carefully.
</p>
<p>
The forces between atoms are shown by dashed lines.

Stop the helium model and estimate how many dashed lines there are per atom.
<p> (It is hard to see all the lines. You can assume there is one between every <p>pair that are close.)
