Today in Biology we started an experiment on Osmosis. Osmosis is a type of diffusion that uses water movement to make the solution Isotonic (even out the concentration). For the experiment, we had to put two spoons of sugar in a beaker with 150ml of water. We had to do this three times one had salt another had sugar and one just had water.
Hypertonic - High
Hypotonic - Low
Isotonic - Equal
Gummy Bear in Salt Water: I think that this gummy bear is going to get smaller because the salt does not dissolve the same as sugar which means that with all the salt mixed in the water the gummy bear won't be able to absorb much if any water.
Gummy Bear in Sugar Water: I think that the gummy bear in the sugar water is going to get a little bit bigger but not a lot because since there is sugar in the water it won't be able to absorb all of the water.

Next Day
Gummy Bear in Water: The gummy bear is bigger than it was yesterday but it did not get as big as I thought it would get.it also broke a little bit bit. This means that the gummy bear is hypertonic to the water because the water was able to get in the gummy bear.
Gummy Bear in Sugar: I was right that this gummy bear would get bigger but I thought it would be smaller than the water gummy bear but it actually became the biggest gummy bear. This gummy bear is also hypertonic to the sugar water because it was able to absorb a lot of the liquid.
Gummy Bear in Salt: I was somewhat correct with my guess on how the gummy bear would react because it did not get bigger but it did not shrink either. This means that the gummy bear was hypotonic to the saltwater solution and was not able to absorb any of the liquid.
