• 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

Why do objects sink or float in H₂O? 

• 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 

Which box has a higher density?  

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

Jack has a rock. The rock has a mass of 14 g and a volume of 2 cm³. 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 4 g, and a volume of 2 cm³. What is its density?

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

Volume is ...

• Mass/Volume
• The amount of matter in an object.
• The amount of space an object occupies.
• Anything that has mass and occupies space.

Density is...

• the amount of mass in an object
• the amount of space an object takes up
• the amount of mass in a given space
• the weight of an object

Define the term "mass".

• Mass/Volume
• Anything that has mass and takes up space 
• The amount of space an object occupies.
• The amount of matter in an object.
