ELLA ANDERSON Egg Float! ! The purpose of my experiment was to find out how does an egg float in water with flour, sugar, and sea salt. My hypothesis is that if we put an egg in water then it will float because we add salt. To conduct my experiment I needed the following material: Three separate cups of water, 4 Tb. flour, 4 Tb. sugar, 4 Tb. sea salt, 3 eggs, 3 spoons to stir. Once I had my material, I did the experiment. T h e independent variable was the fact that I changed the cups. The dependent variable is what I will measure. The constants/controlled variables were the same cup, same amount of water, and same eggs. In the end, I learned that salt can keep an egg afloat. I learned that if you add flour to water the egg will still sink. If you add sugar to water then the egg will also sink. But it will stay afloat if I used the salt. This shows me that it is easier to float in salt water then in the other thing I tested.
