Experimental results have established that very dense partonic matter is formed in Au+Au collisions at RHIC. At such high density, it is believed that quarks and gluons are no longer confined in hadrons, but become constitutes of a quark-gluon plasma (QGP). To understand the properties of the dense matter, it is importnat to measure as many observables as possible and to relate them together to reconstruct the entire time evolution of the system. A large amount of data is now available on low p_T hadrons, high p_T suppression, modificaiton of jet correlation, heavy quarks, J/ψ, lepton pairs and direct photons. Recent experimental data from RHIC on these measurements are reviewed.
