This is the density column from the Making a Density Column video. Notice that the olives are floating at the boundary between the water and the corn syrup. What does that tell us?
-
The olives are less dense than the water, and more dense than the corn syrup.
No. If the olives were less dense than the water, they would float on top of the water layer. -
The water is denser than the olives.
No. If the water was denser than the olives, then the olives would float on top of the water layer. -
The corn syrup is less dense than the olives.
No. If the corn syrup was less dense than the olives, the olives would sink all the way to the bottom. -
Olives are denser than water, and less dense than corn syrup.
Yes! Because the olives are denser than water, they sink to the bottom of the water layer. Because they are less dense than corn syrup, the olives float on top of the corn syrup layer.

SC.8.P.8.4 Classify and compare substances on the basis of characteristic physical properties that can be demonstrated or measured; for example, density, thermal or electrical conductivity, solubility, magnetic properties, melting and boiling points, and know that these properties are independent of the amount of the sample.
