Density - Wikipedia, the free encyclopedia
The density of a material is defined as its mass per unit volume. The symbol of density is ρ (the Greek letter rho). Mathematically: \rho = \frac{m}{V} \, where: \rho (rho) is the density...

They turned over each jar of liquid and then wrote about what they saw. They also wrote what they thought would happen in microgravity and increased gravity. Fata and other teachers from Kilmer did the same experiment on the Weightless Wonder.

Now choose another water insoluble organic liquid with a density less than the first aqueous layer. You can achieve this with mixed solutions of organic compounds so long as both are insoluble in water.

We have mixed three different types of liquids together to prove that one liquid is more dense than the other, and will separate. In other words, one liquid is heavier than the other. I am having problem applying this concept to everyday life, ... To me density is very important when it comes to moving a fluid around.

Ask students if they have seen examples of liquid density differences in the "real world." Perhaps they have noticed oil or other liquids in water puddles on the ground, or maybe they've strained to get the tasty garlicky part of the salad dressing out of the bottle before the oil.

CiteSeerX - Document Details (Isaac Councill, Lee Giles): The force between two inert, planar surfaces in a liquid is discussed, focusing on the effect of the reduction in the fluid density between the surfaces. ...

3. Introduce a new term density. When one liquid has more mass than another and takes up the same amount of space, we say it has a greater density. 4. Next, have the students observe as you slowly pour the alcohol into the glass with the soap.
