Why does ice float?

• Liquid water is less dense than solid water.
• Solid water is less dense than liquid water.
• Gaseous water is less dense than solid water.
• Liquid water is less dense than gaseous water.

What do we know about the density of lamp oil, rubbing alcohol, and vegetable oil?  

• The density is greater than 1.0 g/mL
• The density is less than 1.0 g/mL
• The density is equal to 1.0 g/mL
• The density can not be determined

If an object has a density of 3.6 g/cm^3 and you put it into water, will it sink or float?  

• sink
• float

Look at this image.  Which object has the LOWEST density in water? How? 

• The Ping Pong Ball because it floats to the top 
• The bolt because it has sunk to the bottom
• The soda cap because it is not just full of air like the Ping Pong ball

Why do the liquids form different layers?

• They have different densities.  
• They have different masses.  
• They have different volumes.  
• They are different temperatures.  

Why do ice cubes float in a  glass of water?

• the ice cubes are more dense than the water
• the water is more dense than the ice cubes
• the water is more dense than the glass
• the ice is more dense than the glass

A scientist has four different liquids and pours them all into a bottle.  The silver liquid sinks to the bottom, the red liquid settles on top of the silver one, and the pink liquid stays at the surface. Which liquid has the smallest density?

• the pink liquid
• the silver liquid
• the red liquid
• the water
