This 12 slide powerpoint presentation describes matter, the atom, and the subatomic particles (the proton, neutron, and electron). It is illustrated and animated to best show what an atom is and what it is made of on the 4th, 5th, and/or 6th grade level. This would be a good supplement to a unit or chapter discussion of the atom.
