Density: sink or float?Slide2
Liquid Layers
If you pour together liquids that don’t mix and have different densities, they will form liquid layers.
The liquid with the
highest density
will be
on the bottom
.
The liquid with the
lowest density
will be
on the top
. Slide3

Sink or Float
Ice floats in water because the density of ice is less than the density of water.
Aluminum sinks because its density is greater than the density of water.

Water, Oil…and a Superball
The oil is less dense than the water, so it’s on top. The superball is less dense than water, but more dense than oil, so it sinks to the bottom of the oil layer, yet floats on the top of the water layer.Slide5

Think About This
The density of five liquids are measured as follows:
Liquid 1: 1.0 g/mL
Liquid 2: 1.38 g/mL
Liquid 3: 0.77 g/mL
Liquid 4: 2.95 g/mL
Liquid 5: 0.056 g/mLDraw a picture of all 5 liquids in a test tube how they would layer according to densitySlide13
