An experiment is any actual trial to test a hypothesis. An example would be to grow two plants, one in normal soil, and one with fertilizer to test the effects the fertilizer has. (BTW, the normal soil plant is the control, and the fertilizer plant would be the experimental)
For example the preparation of barium sulfate:
BaCl2 + Na2SO4 = BaSO4 + 2 NaCl
