dulum.My hypothesis was that the suspended mass and the displacement would affect the period of the pendulum. My hypothesis was partially correct. I learned that the length of suspension also affects the period of a pendulum. The lower the length of suspension is the lower the time for a pendulum to complete a cycle. Connections/Textbook Research:1. independent variable- “The variable that’s regulated by the scientist. The independent variable can be chosen before conducting the experiment.” e.g. time.dependent variable- “The variable that changes as a result of the independent variable. This is the unknown factor and the reason for doing the investigation. The values of the dependent variable are determined only after the experiment has been conducted.” e.g. speed. Source- Reference 5 H. M and E Graphing techniques.2. In this experiment the independent variables were the length of suspension, displacement, and the mass (bob) because they were the variables we could change. The dependent variable was the period of the pendulum because that was what we were measuring.3.It’s important to test one independent variable at a time because if you test more than one at a time there will be no control and you won’t know which variable affected the experiment.4. The term control means “An experiment ran without a variable(s) in order to show that any data from the experimental setup was due only to the variable that was being tested.”This is a controlled experiment because we always kept two variables the same.Source- Exploring Physical Science, 1997, page 13.5. qualitative observation- “the observations of the characteristics of something.”quantitative observation- “the observation of the magnitude, size, extent, or amount of something.” Source- http://www.harcourt.com/dictionary/6. “A hypothesis is a proposed solution to a scientific problem.
