Purpose of this experiment was find best salt concentration for hatching brine shrimp. We have this experiment with many materials and safety glasses. Best concentration  was 6% of salt concentration. It has 216 hatching brine shrimp in Petri dishes. After this concentration, hatching of brine shrimp was decrease. And small number of hatching brine shrimp was 64, 2% of salt concentration. We learn brine shrimp is not hatching any salt concentration. Another thing is influenced by temperature and light. Because other group’s result was different with our result. Our error was salt got stuck to edges. We were having to more stir. We was spilled some water at stirring. And we can’t put correct salt. I think Hypothesis-higher salt concentration is the more shrimp will hatch. However, after certain limit, the shrimp will die- was almost correct. But my opinion is it’s not problem of high or low salt concentration. Just perfect salt concentration what shrimp’s favorite rate can hatch many eggs. But of course not appear much at very low and high concentration 아나 안그래도 테스트 55문제중에 15개 틀려서 간당간당한디 흑흑 나 쥬니어때 괜히 온거가테잉 ㅠ.ㅠ
