Solid and liquid states

Science

In the Heating and cooling (physics) unit, they will build on this knowledge to learn how the motion of particles in solids, liquids and gases changes when they are heated, how thermal conduction and insulation work and why heating different materials doesn’t always increase their temperatures by the same amount. 

In Y4 of primary science, pupils learnt about ‘solids, liquids and gases’ and changes of state.

Solid, liquid, gas states and changes of state

Substances can exist in three different states of matter. The solid state is one of the three states of matter, what are the other states of matter?

Match the state of matter to the example or a substance in that state. 

Which of these descriptions describes how the the particles a solid state are arranged?

Which of these descriptions describes how the particles in a liquid state are arranged?

A substance in the liquid state has particles that are free to move past their neighbouring particles, this means that they can {{}} and can take the shape of a container.

A substance in the liquid state and solid state has no space between the particles. This means that substances in liquid states or solid states cannot be {{}}.

Complete the sentence. All materials and substances that behave the same can be {{}} into categories.

What state of matter is the water in the bottle?

The balloons are filled with helium, what state of matter is helium at room temperature?

Liquid state is one of the states of matter.  What are the other states of matter called?

All materials and substances can be sorted by the way they behave. Complete the sentence: These behaviours are called the {{}} of a material or substance.

Match the property to the state of matter.
