In this lab we tested grapes when submerged in four different solutions. We put the grapes into saltwater, sugar water, water, and grape juice. In my hypothesis I stated that when a grape is put into saltwater, the grape will shrivel because the solution is hypertonic. This hypothesis was correct. The water moved out of the grape and into the solution. I also said, when a grape is put into sugar water, the grape will stay the same because the solution is isotonic. This hypothesis is incorrect because when we weighed the grape from the sugar water solution, the grape swelled up. This shows that the water moved from the solution into the grape. My hypothesis for water was correct. I said, if we put a grape in water, then the grape will swell because the solution is hypotonic. Hypotonic means that the water moved from the solution into the grape. For my last hypothesis I said, when a grape is placed in grape juice, the grape will stay the same because the solution is isotonic. I was correct, when we measured the grape from grape juice there was a very small difference showing that the solution was isotonic. The water was still moving in and out of the grape but is did not cause the grape to shrivel or swell. This lab shows me that eating too much salt would make our cells shrivel up just like the grape did.
