The invention provides a teaching apparatus for demonstrating the free liquid surface effect, belonging to the field of education supplies. The teaching apparatus is composed of an experiment stand, an overturning plate, a ship model, a storage tank, a grooved rod rack, a grooved rod, a multi-level turntable and a solid filler, wherein the overturning plate is mounted between holes formed in the experiment stand, the multi-level turntable is mounted on the experiment stand and is driven by a motor, one end of the grooved rod is mounted in any hole formed in the multi-level turntable, and the other end of the grooved rod is inserted into the grooved rod rack. The ship model is placed on the overturning plate, the storage tank is placed on the ship model, and the solid filler is placed in the storage tank. With the adoption of the ship model, the influences of the free liquid surface effect on the boat can be vividly simulated, and the experimental result is visual and stereoscopic; a plurality of small holes a
