Ocean acidification is a rising issue in the field in environmental sciences. In this experiment we will determine the effects that acidity has on aquatic organisms through observing the physical changes that occur when umbionium seashells are placed in varying pH environments. There will be five experimental groups and one control group. In each group, 5 seashells will undergo experimentation. The five experimental groups include placing these seashells in the following: 1 cup of dawn soap, 1 cup of 2% milk, 1 cup tomato juice, 1 cup coca-cola, and 1 cup lemon juice. In the control group, five seashells will be placed in 1 cup of deionized water. The seashell’s weight, texture, and color will be recorded every other day for 2 weeks in order to determine the effects that pH has on seashells.
