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

Frank has an eraser. It has a mass of 4g, and a volume of 2cm³. What is its density?

• 8 g/cm³
• 2 g/cm³
• 1/2 g/cm³
• 24 g/cm³

What is the formula for density?

• density = mass x volume
• density = mass / volume
• density = mass + volume
• density = mass - volume
