The video uses the definition of osmosis to develop a hypothesis, which is tested through an experiment involving potato cylinders and various concentrations of sugar solution. The video explains the independent, dependent, and control variables involved in the experiment, and discusses two methods of analyzing the results. A scatter graph of percentage change in mass against sugar concentration is plotted, and a curve of best fit is drawn to show the relationship between the two variables. The conclusion supports the hypothesis developed based on the definition of osmosis.\n
