When the egg was placed into syrup, a hypertonic solution, it shrunk in size. This result supports my hypothesis. The mass of the egg before it was placed in syrup and after it was placed in syrup changed drastically. There was a 16 g decrease in mass that happened to the egg during its time in the syrup. Both the long and short circumference of the egg decreased. The long circumference before the egg was placed in syrup was 18.75 cm and after it was taken out of the syrup the long circumference was 16.9 cm, a decrease of 1.67 cm from before the syrup. The short circumference before the egg was placed in syrup was 16.15 cm and after it was take out of the syrup the short circumference was 15.1 cm, a decrease of 1.05 from before the syrup.

This result supports my hypothesis. The mass of the egg before it was placed into the distilled water and after it was taken out of the distilled water increased quite a bit. The mass before was 74.48 g and the mass after was 89.48 g, a 15 g increase. Both the long and short circumferences of the egg increased also, which further proves that distilled water is a hypotonic solution. The long circumference before the egg was placed in was 16.9 cm and 18.4 cm after the egg was taken out, which is a 1.5 cm increase. A 1.5 cm increase for an egg is quite drastically and proves that it wasn’t just a mistake that we accidentally made. The short circumference of the egg was 15.1 cm before the egg was placed in the distilled water and 16.5 cm after it was taken out, a 1.4 cm increase. The volume of the distilled water in the beaker also changed while the egg was in there. The volume of liquid in the beaker before the egg was placed in was 150 mL, and when the egg was taken out, the volume decreased to 130 mL. This proves that some of the distilled water that was in the beaker passed through the cell membrane and into the egg, which explains why the mass of the mass increased, while the volume of water decreased. The distilled water didn’t have any minerals or gunk that prevented it from going through the cell membrane easily, while the liquid that was in the egg must of had larger molecules, which made it harder for the liquid inside the egg to pass through the cell membrane into the
