 * TESTING EGGS THAT ARE SOAKED IN DIFFERENT TYPES OF LIQUIDS **

The primary purpose of this experiment was to see how different liquids would affect the egg shells the most in forty eight hours. Another purpose for this experiment was to see if toothpaste protected the eggs from being altered. It was hypothesized that the vinegar would affect the egg shells the most and also it was hypothesized that the toothpaste would protect the egg shells from being changed by the liquids. It was hypothesized because toothpaste is used on teeth and teeth and egg shells are made up of the same material (calcium carbonate). If toothpaste protects teeth then it should protect egg shells. This experiment was performed by placing egg shells in liquid for forty eight hours and recording the weights and color of the egg shells before and after the experiment. The data was recorded for each sample of egg shells placed in each liquid. After forty eight hours of being soaked, the liquids were removed and observed changes were recorded. The data was recorded to compare the egg shells before and after the experiment. At the conclusion of all the experiments, the vinegar made the greatest effect on the egg shells. The toothpaste did protect the egg shells from changing as much.
 * ABSTRACT **

**EXPERIMENTAL IMPROVEMENTS AND FUTURE EXPERIMENTS**

To improve this experiment the mass and weight should be measured before the experiment. Also eggs should be kept in the same amount of light/darkness that is because the light might evaporate the liquids quicker than when it is in the dark. Also make sure that the temperature is exactly the same the whole experiment. Future experiments could look at how long it takes the eggs to fully disintegrate. That would test which liquids not only affect the eggs but disintegrate them also. An interesting experiment would to see if the amount of light and the temperature affected what the liquid did to the eggs. For example if you have one egg in room temperature with a normal amount of light, there would be another egg under less or more light and a hotter or colder temperature.
