What is a hypothesis for pH?
If you measure water through pH, then you will get different levels of acidity.
What is the independent variable of pH
The color of papers
What is the dependent variable of pH
The result from the different substances
What is salinity
The total amount of dissolved salts in a sample of water measured by parts per thousand
What is water density
The "heaviness" in an even volume
What is denser warm water or cold water?
Cold water
What has a higher density salt water or fresh water?
Salt water
What will happen if waters of different densities come in contact
The one that has less density will float to the top.
Why does the egg float when salt is added to a glass of water
The egg has a higher density then salt water
