Density

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

Helium balloons rise on earth because

• helium is less dense than air
• helium is more dense than air
• helium is cooler than air
• helium is warmer than air

True or False:  The density of a specific type of material never changes.  

• True
• False

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 objects sink or float in water?

• Because their densities are higher or lower than compared to water

• Because their densities are using gravity to pull down

• Because their densities are heavier or lighter

• Because their mass and volumes are equal

Will an object with a density of 0.999 sink or float in water?

• sink
• float

An object that is more dense than the fluid in which it is immersed will

• sink
• rise
• neither rise nor sink
• sink at first, than rise slowly

Which is least dense? 

• A
• B
• C

What two types of measurements make up DENSITY? 

• Mass and Volume
• Temperature and Mass
• Grams and Centimeters
• Volume and Weight
