This is a nice, brief (~5 minute) overview of the Standard Model of particle physics. The SM is the current theory of matter and forces, with the one exception of gravity. This was also made just before the discovery of the Higgs boson, but it mentions where the Higgs fits in. If you are interested in more details, see Doc V! Keep in mind that in the particle physicist's mind, we are not made from electrons, protons and neutrons - we are made from electrons, up quarks and down quarks! Check it out for a primer.
