Scenario 3
Ruben wants to determine if listening to different types of music will have an effect on a person’s pulse. His hypothesis states that if a person listens to rap music, their pulse will increase more than if they listen to other types of music. Ruben takes each participant’s pulse before, during, and after listening to 30 minutes of music. He has his mother listen to rock music, his sister listen to classical music, and his friend listen to rap music. From the data collected, he determined that rap music raises a person’s pulse the most
1. Identify the independent and dependent variables in Ruben’s hypothesis.
The independent Variable is the persons pulse and the dependent variable is the different types of music. 2. Despite the results, this experiment is not able to support Ruben’s hypothesis. Suggest specific improvements that will make the experiment test the given hypothesis. Explain why these changes are improvements.
Well first off, the test subjects (his family) are different ages and sexes so that affects the test outcome so he should do the same test on everybody because not everyone’s pulse is the same. If he changes that he will have results on all the subjects for all the types of music and he can see which music really affects a person’s pulse.
Part 2
Oil in a cup experiment
Purpose: I want to find out what is heavier the oil, water or the dishwashing liquid
Research: I will have to find information on the items in the cup that I want to sink and float
Hypothesis: I will guess what will happen when I mix these items in a cup and tell whether I think the oil will sink under the water or float
Experiment: I will have to actually do the experiment and put all the items in the cup
Analysis: I will have to chart down what happened and I could put the time it too to actually form then compare my results to the other times I had to repeat the experiment, to see if I get the same
