Describe an experiment to investigate the effect of a range of concentrations of sugar solutions on the mass of a potato. Ensure you include the following:

1. Aim of the investigation: Clearly state the objective of your experiment.
2. Independent variable: Identify the variable that you will change (e.g., concentration of sugar solutions).
3. Dependent variable: Identify the variable that you will measure (e.g., mass of the potato).
4. Control variables: List the variables that need to be kept constant to ensure a fair test (e.g., temperature, size of potato pieces, duration of experiment).
5. Expected results: Describe what you anticipate observing in the results.
6. Explanation of expected results: Provide a rationale for the expected pattern in the results.

The experiment aims to investigate how different sugar concentrations affect a potato's mass, with higher sugar concentrations expected to decrease the potato's mass due to osmosis.

Explanation:

The aim of the investigation: To determine the effect of different concentrations of sugar solutions on the mass of a potato.

Independent variable: Concentration of sugar solution

Dependent variable: Mass of the potato

Control variables: Initial mass of the potato, duration of the experiment, temperature, type of potato, volume of sugar solution

Expected results: As the concentration of sugar solution increases, the mass of the potato is expected to decrease. This is because of osmosis, where water moves from an area of low solute concentration (potato cells) to an area of high solute concentration (sugar solution).
