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

If an object has a density of .6 g/mL and you put it into water, will it sink or float?  

• sink

• float

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

• sink

• float
