Density

Put the liquids in order from most dense to least dense?

• 4, 3, 2, 1
• 1, 2, 3, 4
• 3, 4, 2, 1, 
• 4, 3, 1, 2

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

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

Which liquid is the least dense?

• oil
• water
• syrup 
• plastic bottle

Which liquid is the most dense?  

• oil
• water
• syrup
• plastic bottle

Why do some substances float on water?

• they are warmer than water
• they are cooler than water
• they are more dense than water
• they are less dense than water

A brick sinks in water while a wooden block of the same size floats.  This is because the brick has a

• lower volume than the wooden block
• lower density than the wooden block
• higher volume than the wooden block
• higher density than the wooden block

An object should float in a liquid if it is 

• Denser than the liquid 
• Less dense than the liquid
• Lighter than metal
•  Shaped like a ball 

Put the liquids in order from most dense to least dense?

• 4, 3, 2, 1
• 1, 2, 3, 4
• 3, 4, 2, 1, 
• 4, 3, 1, 2

If you poured 3 liquids that do not mix how could you tell which one is the most dense?
