Recently, my dad taught me ‘The Standard Model’ of physics. It is made up of quarks, leptons and bosons. Three quarks make up a proton or a neutron. It depends what the combination of quarks are there to make different hadrons (proton/neutron), e.g. 2 up quarks and 1 down quark make a proton, 1 up quark and 2 down quarks make a neutron. I know that because an up quark has a +2/3 charge and a down quark has a -1/3 charge. The Higgs Boson is an undiscovered particle that will explain mass. I drew a diagram to explain better:
The Standard Model
I also drew another diagram showing what makes matter, it explains how crucial quarks are to make everything. It also shows what everything is made of and the layout of atoms, molecules, nuclei and quarks. Oh and what quarks are made of is still a mystery (some people think it could be strings, but that sounds silly to me, haha silly strings 
). Here is the diagram:
