Density

What two types of measurements make up DENSITY? 

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

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

Jack has a rock. The rock has a mass of 14g and a volume of 2cm³. What is the density of the rock?

• 7 mL
• 7 g/cm³
• 28 g/cm³
• 1/7 g/cm³

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 units are used to measure mass?

• g
• cm³
• g/cm³
• cm³/g

What is the formula for density?

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

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

• True
