The present invention relates to a submarine probe for science teaching materials. The submarine probe helps students to easily understand the principle of a submarine through a transparent probe, saves resources, and protects environment by enabling the manufacture thereof using wastes. Moreover, the submarine probe enables the real time probing of ocean floor by enabling the adjustment of rise and fall through the buoyancy control of the submarine probe and enables the accumulation of changes in temperature and pressure. |
