 * THE GROWTH OF DIFFERENT TYPES OF GUMMY WORMS IN LIQUID **

The purpose of this experiment was to test how gummy worms would react if soaked in water for different periods of time. Gummy worms have gelatin in them, making them hydrophilic and the gelatin absorbs the water making it grow and making it weaker. The gummies were soaked in water for different amounts of time and then were put on a spring scale to measure how much force it took to break the gummy. The longer the gummy soaked, the weaker it got. The gelatin in the gummy started to absorb the water which caused the gummy to have more room between the molecules, making it easier to break.
 * ABSTRACT **

Instead of leaving the gummies soaking while the others were being measured, all the gummies could have been removed so they wouldn't have been soaked any longer than all the others. Also, the gummies could have been hooked on at the same spot instead of slightly different places. One future experiment that could be done is testing different brands of gummy worms. Another that could be done is different amounts of liquids that the gummies are soaked in.
