Topic – solids, liquids and gases

Friday 11 January 2019

We have a started a Science based mini-topic called ‘What’s the matter?’ The children are learning  about different states of matter and their properties. Understanding matter is an important part of science.

We began by  discussing how everything is made up of matter. Matter can be in these different states: solid, liquid or gas. If you look around, you can see all sorts of objects, these are solids. Ice is solid water. Drinks are liquids. Air is the invisible matter surrounding us. Air is a mixture of gases – oxygen and carbon dioxide for example. Steam, or water vapour, is water in the form of a gas.

Here, we used marbles to show how the particles in a solid, liquid or gas behave.
“The particles have spread out and don’t keep the shape. This how a liquid behaves.”
“The marbles are spreading out all over the place! This is how a gas behaves.”
As you can see, the children were captivated by this new learning. Some of their questions demonstrated secure understanding and a curiosity to find out more. “If you poured a liquid out of a container, would it just keep on spreading out?” asked Sami.

 

The children noted that particles in a
gas are well separated with no regular arrangement.
In a liquid,  the particles are close together with no regular arrangement and in a solid are tightly packed, usually in a regular pattern. Solids have a fixed shape that is difficult to change.Image result for solids liquids and gases ks2Then, we  went on to sort items into groups. Ask your child what type of diagram we were using in the picture.

After grouping items into the 3 types of matter, the children began to ask questions and challenge some of their classification decisions.
“Water can be solid.” stated Sami.
“Can the shape of some solids be changed?” questioned Kashif.

Throughout our lesson, the children were learning some new, scientific vocabulary. Can your child remember any?

Below, there are a few quiz questions for you to ask  your children at home.

1, Which of these is not true of solids?

Solids can be cut or shaped
A solid expands to fill its container
Solids will stay the same shape and size unless acted upon by a force
Solids can be grasped (held on to)
2, Which of these has the least densely
(a closely compacted or crowded manner) packed particles?
Solids
Liquids
Gases
Both liquids and gases
3, Which has the most densely-packed particles?
Solids
Liquids
Gases
Particles are equally dense in solids, liquids and gases
4, Which of these is not true of liquids?
The shape of a liquid does not change
A liquid takes the shape of its container
Liquids are runny and can be poured
The volume of a liquid does not change
