Osmosis Experiment

In Biology Science, we did an osmosis experiment where we put an equal amount of solute in 3 different beakers. In the 2 different beakers, we put different solutes- salt and sugar.  In the other beaker, we didn't put any solute, it was just plain water. Water is the solvent in this experiment, meaning the solute(salt and sugar) is being dissolved in the water creating a solution. 

Osmosis: Water movement across the seme-permeable membrane. From high concentration to low concentration

Hypothesis: The solution can be Isotonic(met equilibrium), Hypotonic(low concentration solute), and Hypertonic(high concentration solute). 

For the gummy bear in just water, I think the gummy bear will expand in size and volume due to being hypertonic compared to just normal water. Meaning the water will enter the gummy bear. 

The gummy bear in the salt solution will shrivel in size and volume because of hypotonicity, the water will leave. This is also because there are three-tablespoon scoops of salt and there is also only 50ml of water. 

While the gummy bear is in the sugar solution, I think it will increase in size and volume mass. The sugar solution will enter the gummy bear as there are more sugar molecules in the gummy bear than in the water. 
Despite the fact that I think that they are isotonic compared to sugar water. I still think there would be changes in the gummy bear.

Results:

After one day of gummy bears being soaked in the solution, I have seen that my hypothesis matches the outcome of our experiment. 

Normal Water - The gummy bear in just water increases in size and mass the most. The colour of the gummy also wears off, it almost becomes transparent. It is also very easy to break once you applied pressure on it. This is because the gummy bear is hypertonic to water. 

Salt solution - Meanwhile, the gummy in salt solution decrease in size and mass. It also becomes firm and hard, even when pressure is applied. There were also little bubbles around the gummy bears when it was soaked in the solution. This is because the gummy bear is hypotonic to water. As the water solution is more concentrated than the gummy.

Sugar Solution - The gummy bear in the sugar solution has also increased in size and mass but is not as big as the gummy bear in the regular water. The gummy bear is less fragile compared to the gummy in water, but it is also almost transparent despite still having colour. The reason why it slightly increases in size and mass is there is still more sugar molecule in the gummy bear compared to the sugar solution.
