Investigating the Effects of Sugar Solutions on the Mass of Plant Material through Osmosis Experiment

The video tutorial explores an experiment to study the effects of sugar solution concentrations on potato mass through osmosis. It defines osmosis, formulates a hypothesis, and outlines the experimental procedure, including the use of a cork borer to prepare potato cylinders. The video explains the independent, dependent, and control variables, and describes two methods for analyzing results: calculating water uptake rate and percentage mass change. It concludes by interpreting the results, showing that the potato gains or loses mass based on the sugar concentration, supporting the hypothesis.

What is osmosis and how does it relate to the mass change in potato cells?

Describe the steps taken to prepare the potato cylinders for the experiment.

What are the independent and dependent variables in this osmosis experiment?

Explain how the control variables affect the experiment and why they need to be kept constant.

What conclusions can be drawn from the results regarding the concentration of sugar solutions and the mass of potato?
