Liquids can be thin and thick.
Liquids can also come in a range of colours.
Liquids can be heated and cooled.
A liquid is something that you cannot hold.
Some liquids like fruit juices can also have pulp suspended within it.
Liquids do not have a permanent shape, but some can be frozen into a 3D solid.
It is hard to show someone unless it is in a bottle or container.
All liquids have a different viscosity.
Liquids are usually a wet, moist material; they can also have a strong scent.
A liquid is a flowing state of matter.
Most liquids can also be evaporated.
Scientists have different names for liquids like H2O but we recognise them as what they are.
