What is the dependent variable of the osmosis practical?
1. Making sure we weigh and measure the potato before completing the test.
2. The different solutions that the potato was placed in.
3. The change of mass of the potato.
The dependent variable in the osmosis practical is the change of mass of the potato (option 3). This is because the change in mass of the potato will be impacted by the different solutions it is placed in (option 2). The weighing and measuring of the potato before the test (option 1) is important for establishing a starting point, but it is not the dependent variable being measured or affected by the experiment.
The dependent variable of the osmosis practical is the change of mass of the potato.
To determine the dependent variable, first, you need to identify the factor that is being measured or observed to see how it changes in response to the independent variable. In this case, the independent variable is the different solutions that the potato was placed in.
During the osmosis practical, the potato is placed in different solutions with varying concentrations. By measuring the change of mass of the potato before and after being exposed to the solution, we can observe how the concentration of the solution affects the movement of water into or out of the potato cells through osmosis. Therefore, the change of mass of the potato is the dependent variable in this experiment.
