Materials:
-1 Large Container of Water
-1 Bar Ivory Soap
-1 Bar of an other Brand of Soap
-1 Can Coke
-1Can Diet Coke
-1 16lb. Bowling Ball
Procedure:
Fill a large container with water. Place a bar of Ivory soap
and a bar of another brand of soap in the water. Which one floats? Next place the cans of Diet Coke and Coke in the water. Which one floats? Now for the two bowling balls...Which on floats?
What's Going On?When an object is placed in water it displaces its' weight in water. The objects that float in water are less dense than water. Density is a measure of how much mass is present in a given volume. The desnity of water is 1 gm/cm3. The density of an 8lb. bowling ball is less than 1gm/cm3. The bar of Ivory soap contains more air than most other brands. This makes Ivory soap less dense than water. Coke will sink because there are many grams of sugar added to the regular soft drink. Both the diet and regular liquids are more dense than water, however, add carbonation and it is just enough to float the diet soda.
