Lumbriculus variegatus

What Makes a Worm?s Heart Race? Part 1 - Learning Name: Hour: Date: Purpose: To explore the impact of treatments on the pulse rate of the worm Lumbriculus variegatus while refreshing and refining your understanding of experimental design with a focus on recognizing and minimizing experimental bias. Objectives: Upon completion of this activity, you should be able to: Count pulse rate in blackworms (Lumbriculus variegatus). Demonstrate the ability to design and perform an experiment using the strong inference model and multiple hypotheses with attention to the minimization of experimental bias. Demonstrate an understanding of graphing and the use of simple statistical data analysis to evaluate the impact of an experimental treatment.
