Gummy Bear Lab Report

1183 Words | 5 Pages

The mass and length of gummy bears either increase or decrease in specific solutions. Depending on the acidity, sugar-to-water ratio, viscosity, and other factors, the gummy bear was more prone to expand or shrink. For example, the gummy bear submerged in the sugar solution increased in mass and length due to the ratio of sugar in the solution while the concentration of rubbing alcohol caused the gummy bear to shrink and shrivel up.
