• It is not possible to measure mass

What is volume?

• The concentration of matter

• The amount of matter of an object

• The amount of space an object occupies

• The weight of an object

If an objects floats...

• The density is higher than the density of water

• The mass is higher than the mass of water

• The mass is lower than the mass of water

• The density is lower than the density of water

Which material is made form sand and other materials?

• Textile

• Glass

• Carbon

• Wood

What do we need to calculate the volume of something?

• A scale

• A cylinder

• Water and a scale

• Water and a cylinder

Which object has got a smaller mass?

• The pencil

• The shoe

• Both (Los dos)

• We can't measure mass with a scale

The density is...

• The concentration of matter in a particular mass

• The concentration of matter in a particular volume

• The space that an object occupies

• The volume and the mass of an object
