1. Iâm providing you with the topic. It is the % correlation between a normal resting pulse rate and a pulse rate after 30 seconds of jogging in place. Your job is to form a hypothesis regarding what percentage you believe that correlation is and then do an experiment that either proves or disproves your hypothesis. If your experiment disproves your hypothesis, thatâs called a ânull hypothesisâ and that is just fine. Most of science is founded on hypotheses that are null in total or on part. If every idea and notion were always right, then there would be no need for the scientific method right? Iâll be looking to see how well you concocted your hypothesis and experiment, performed the experiment, presented your data and formed your conclusions.
2. Youâll need to write your paper with the following in mind. You must form an observation and then introduce some background information regarding it. The general idea is that you should be able to grab a stranger off the street and give them your paper and they should be able to understand what your paper is about and be able to completely duplicate your experiment. Details as to what is required is paramount so donât skimp out with those details about what you did in the experiment. List all the materials needed to perform the experiment. List the steps in the experiment. Provide easily understandable data tables and graphs. Your graph/s are based upon the data you collect and put in the data tables. Graphs must be titled, must have the axis titled correctly, must have a legend, must use a best fit line, must have the proper units marked and must show all data points. Finally you must analyze your data and determine whether or not your data collected proves your hypothesis or not and reach a conclusion about that. Also, if during the experiment you discover ways to make the experiment better for others trying to duplicate your work, in the conclusion is where you should mention that.
3. You will need 25 data points. You would then collect all that information and compile it into a data table and a graph. In this experimentâs case a data point is just a person (the subject) being measured.
4. Hereâs a link to get you started with making your data table.
