Pulse Lab Report
This lab experiment investigates the effect of listening to different types of music on one’s pulse. The experiment relates the circulatory system to the pulse as it measures how quickly the heart contracts and releases blood. Pulse is measured in beats per minute (bpm). One’s pulse is loudest near the heart, because there is more pressure closer to the heart. In contrast, one’s pulse is quieter the further away it is measured from the heart, because there is less pressure the further the distance away from the heart. The design of the experiment includes an independent variable, a dependent variable, one control group, four experimental groups, and three constants, which will be defined in detail later in the lab report. The experiment tests

The independent variable, which the scientist controls, is the type of music, such as classical, pop, rap, and heavy metal. The dependent variable, which is determined by the independent variable, is the subject’s pulse (bpm). The control group is listening to no music, since this is when a subject experiences a resting pulse. This control group will be compared to the four experimental groups, which are: listening to classical music, listening to pop music, listening to rap music, and listening to heavy metal music. The three constants in this experiment, which are kept the same for each trial, include the time listening to music, the time between each trial, and the volume of the music. The reason to include constants in an experiment is to isolate the effect of the independent variable on the dependent …show more content…

In this experiment there are three subjects, Isabella, Ava, and Olivia. Isabella is a healthy 91 pound, 5’2”, 13-year-old girl with low blood pressure. Ava is a healthy 93 pound, 5’, 12-year-old girl with normal blood pressure. Olivia is a healthy 92 pound, 5’3”, 13-year-old girl with low blood
