Density is weight divided by volume, or weight per unit of volume. How about comparing a steel ball and a cork ball the same size? The steel ball weighs more - it has more weight for the same size chunk.

I don't know if that works - my daughter is now teaching high school physics (too far away to ask), so I haven't had to explain this stuff for a long time. But keep at it, 'cause physics is half of how the world works - the other half is psychology (I think).

Good luck!
