In the investigation, the independent variable was the type of liquid in which the eggs were soaked. The dependent variable was the change in the eggs' weight and texture after soaking in different liquids. The control variable was the duration of time the eggs were soaked, which remained constant.

In the part of the experiment with the eggs, the variables used were as follows:

1. Independent Variable: Type of liquid - different liquids were used for soaking the eggs, such as water, vinegar, and soda.
2. Dependent Variables:
a. Weight change: The change in weight of the eggs after soaking in different liquids was measured.
b. Texture: The change in texture or softness of the eggs' shell after soaking in different liquids was observed and recorded.
3. Control Variable:
a. Duration of soaking: The eggs were soaked in each liquid for the same amount of time to ensure consistency.
