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

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 0.6 g/mL and you put it into water, will it sink or float?

• Sink

• Float

Which box has a higher density?  

• Box A
• Box B
• cannot be determined
• they are the same

Which units of measurement are used for volume?

• gram / centimetre³

• centimetre³

• gram / millilitre³

• millilitre
