Figure 13 This is a picture of the potato cores after 24 hours in.8 concentration of sucrose on the electronic balance.Figure 16 This is a picture of the potato cores after 24 hours in 1.0 concentration of sucrose on the electronic balance. Conclusion: Analysis of results and graph: Analysis Result The results were quite ambiguous and vague.To do this you must pore off the fluid in the cup and use the plastic blue tweezers remove the cores, blot them dry just as you did in the set up phase and final measure them using a plastic weighing tray. Make sure to keep track of the positive and negative changes if they occur.
Hypothesis: The more hypertonic potato cores are to sucrose solution, the more weight potato cores gain.
On the other hand, potato cores will decrease in weight when it is hypotonic to sucrose solution.

Boyer Name: Simon Han In this experiment, we learnt about Osmosis and Diffusion through potato cores in different concentration of sucrose, (water,.2,.4,.6,.8, 1.0).
Research Questions: How does Osmosis affect the weights of object in different concentrations?
Introduction: All cells have membranes that are selectively permeable.Figure 6 This is a picture of a group of potato cores on the electronic balance.Figure 8 This is another set of potato cores on the electronic balance.Osmosis is the process whereby water moves across a cell membrane by diffusion.Diffusion takes place when the molecules of a substance tend to move from areas of higher concentration to areas of lower concentration.Figure 9 This is a picture of our independent variables, which is the concentration of the sucrose.Figure 11 This is a picture of the potato cores after 24 hours in.2 concentration of sucrose on the electronic balance.We realized that the lower the concentration, the higher the potato cores weighed.However, our result was quite off for the potato cores in.8 sucrose concentrations.The graph should decrease, but our graph was decreasing and suddenly crosses the x- axis then down again. The equation of our graph is y = x Our x- intercept of the best- fit line is (1.34, 0).Although our graph and our results were off, it still partially backed up our hypothesis.
