States of matter

UNIT

In this lesson, we will learn about the three states of matter, the properties of each state of matter and how to identify which state of matter a substance is in.

What are the properties of solids, liquids and gases?

In this lesson, we will learn that all matter is made up of particles. Particles are arranged in different ways in solids, liquids and gases giving them different properties. We will also learn how scientists use diagrams to represent the arrangement of particles.

How do particles behave inside solids, liquids and gases?

In this lesson, we will learn what happens to the behaviour and arrangement of particles when they are heated or cooled. We will also investigate some uses of these properties such as cooling gases in order to store them.

What happens when you heat or cool each state of matter?

In this lesson, we will learn about what happens when substances are heated or cooled enough to change state. We will learn about the four main state changes and identify examples of each of them.

What are changes of state and why do they take place?

In this lesson, we will learn about how scientists measure temperature, two major 'fixed points' of a substance (melting and boiling point) and how we can determine the state of matter of a substance at a particular temperature when given these fixed points.

What are melting points and boiling points?

In this lesson, we will learn about substances, like sand, that do not fit into one state of matter. We will also learn about non-Newtonian fluids and investigate their properties.
