Introduction;
Water can move through the different cells due to the difference of water potentials in the cells. If there is a higher solute concentration in the cell than outside the cell, the water will move into the cell. However, if the concentration of inside the cell is lower than the outside, water will not move into the cell. This process is called osmosis.
Research question;
This investigation will determine how different concentrated sugar water will affect to the mass change of the potato cells using the concept of osmosis.
Hypothesis;
I predict that the potato slice in beaker C will gain the most increased mass than beaker B and C. The reason is that since beaker C has a highest concentration among the test beakers, it will affect the most to the potato cells. The movement of water will move actively in beaker C.
Variables;
Independent Variable
In this experiment the independent variable will be the sucrose concentration of water. This is controlled by using a specific amount of sugar that we pour into the distilled water. We will do the activity in the solutions with concentration of 0, 0.25, 0.50%.
Dependent Variable
The dependent variable will be the size of potato slices that goes into the solutions. This depends on the various environmental factors during making a slice of potato such as the thickness of core or the peel of potato. Thus it could differ during the experiment.
Controlled Variable
Anything that can change the result of this experiment will be the controlled variables. Therefore, we need to control variables that can be controlled to get the most accurate and reliable data in this experiment. Also the purpose of an experiment is to find out the cause of the lab and how it affects. Without these variables, it would b e difficult to determine which cause made the effect out of the lab.
Water Level;
Clearly if we have higher
