Hi, for today's Biology lesson, we are experimenting on gummy bears. We're learning about the process of osmosis and we have three different types of beaker with different types of solutions with a gummy bear in each beaker. One beaker consist of 3 spoons of sugar, one is 3 spoons of salt and last one is just water. Water level is 50mL.
Hypothesis: I think that the gummy bear on sitting on the just water beaker will get bigger as the water molecules will enter the gummy bear and the sugar molecules in the gummy bear is hyper tonic to the water.
I think that if we place our gummy bear on salt water, gummy bear will get smaller as there are more salt molecules compared to the gummy bear which will cause the water to move out.
And I think gummy bear is isotonic to the sugar water beaker.
Here's a gummy bearπππππͺπ±πππ I also had 3 gummy bears for me to eat
RESULT
We let the gummy bears sit on their beaker for a day and saw some changes. The gummy bear sitting on the water solution has increased its sized the largest out of all three. Gummy bear sitting on the sugar solution has also increased its size but water bear is still bigger. Looking at the salt solution, the gummy bear has decreased its size and it became tough when you touch it compared to its original size. The remaining two gummy bears became softer and water bear has almost lost its color.
The results have proven that my hypothesis was correct. The gummy bear was hypertonic to the water in terms of sugar. It was isotonic to the sugary water. And the salt water was hypertonic to the gummy bear solution as there are more amount of it compared to water. If there are less water, gummy bear is going to end up having a higher concentration of water, and in order to create an equilibrium the water in the gummy bear will leave as the solution of salt water is hyper tonic.
