Matter is anything that has mass and occupies a space. In this site you will find a lot of illustrations and interactive activities dealing with matter.
Bill Nye
Bill Nye: Hole Y Water
This tutorial from Bill Nye uses an experiment with water and sugar to show how matter is mostly empty space.
PBS
Pbs Learning Media: Molecular Shapes
In this interactive activity from ChemThink, students will learn about covalent molecules and how the VSEPR theory predicts the shapes of covalently-bonded molecules.
Khan Academy

Texas Gateway: Valence Shell Electron Pair Repulsion
Why does the shape of a molecule matter? Learn about how the shape of the molecule not only determines the molecule's properties but also whether it reacts or not. This tutorial reviews of VSEPR and molecular geometry.

Virtual Chembook: Density Applications With Gases
DENSITY is a physical property of matter, as each element and compound has a unique density associated with it. Density defined in a qualitative manner as the measure of the relative "heaviness" of objects with a constant volume. For...
