The present invention relates to a bean sprout cultivator allowing photosynthesis and respiration activities to be simultaneously observed and experienced. The present invention includes: a main body where water support chambers forming a pair are formed on left and right sides with respect to a middle separator, each of the water support chambers having an open upper surface, having a space portion therein, and having supporting steps at four lower corners； a pair of cultivation plates having space portions therein so that beans for bean sprout cultivation can be accommodated, having multiple drain holes in bottom surface floors, and respectively placed on the supporting steps of the water support chambers； a darkroom cover formed of an opaque synthetic resin, having a space portion therein, having an open lower surface, covering the cultivation plate, and placed on an upper surface of the main body； and a main body cover formed of a light-transmitting synthetic resin, having a space portion therein, having an open lower surface, and placed along an upper surface edge of the main body. According to the present invention, the plant photosynthesis and respiration activities can be simultaneously observed, experienced, and taught with bean sprouts used an embodiment. The bean sprouts have a very short cultivation period, and thus students can continue with the observation and learning without losing their interest and the present invention is highly effective for plant growth education. The cultivator has a simple structure and can be manufactured with ease. The cultivator can be manufactured from a synthetic resin material, and thus is light in weight, free from damage during distribution and experiments, and highly economical and useful.본 발명은 광합성 작용과 호흡작용을 동시에 관찰하고 체험할 수 있는 콩나물 재배기에 관한 것으로, 중앙의 분리대를 기준으로 좌우 양측에 각각 상면이 개방되고 내부에 공간부가 형성되며 하측 네 모서리에 받침턱이 형성된 한 쌍의 물 받침실이 형성된 본체와, 내측에 콩나물 재배용 콩을 수용 가능하도록 공간부가 형성되고 저면 바닥에 다수의 출수공이 형성되며 상기 물 받침실의 받침턱에 각각 안착 되는 한 쌍의 재배판과, 비
