Brendan Beecher. Introduction: . . Lumbriculus. . variegatus. , better known as a black worm, is a unique creature. They are used for pulse rate testing because they have transparent skin which allows one to easily observe it’s closed-circulatory system. Black worms are commonly found in shallow bodies of water such as marshes, ponds, or lakes. This experiment is testing the effects of depressants on the worm’s pulse rate. Our group made the hypothesis that if a worm lives in depressant water, then it will have a slower pulse rate than a worm living in plain spring water. . Sohrab. R.. Depressants?.
