Year 7

Particles

This lesson looks at the arrangement and movement of particles that make up solids, liquids and gases as well as the properties of each of these states of matter.

Solids, Liquids and Gases

This lesson looks at the principle of diffusion and how it is relevant to each state of matter along with factors that can affect it.

Diffusion

This lesson looks at the effect that changes of state have on particles and how these state changes can be identified and described using data.

Changes of State

This lesson looks at how changes of state can be investigated and how to determine the state of matter based on melting and boiling points

Investigating changes of state

This lesson looks at the reasons for there being pressure in a gas and the factors that can affect this.

Gas pressure

This lesson looks at the structure of word equations, how chemical reactions happen and why mass always has to be conserved.

Solutions

This lesson reviews the topic so far and introduces exam-style questions to help you improve your approach to application tasks.

Review 1

This lesson looks at the differences between pure and impure substances and the effect this can have on their melting and boiling points.

Pure and impure substances

This lesson looks at separation techniques including filtration and evaporation, the equipment they require and the solutions/mixtures they are appropriate for.

Separating mixtures

This lesson looks at the process of purifying rock salt and incorporates essential maths skills for calculating percentage yield.

Rock salt

This lesson looks at the necessary equipment and method for carrying out simple distillation in addition to drawing up risk assessments for investigations.

Distillation

This lesson looks at separating solutes using chromatography, the equipment involved in this and how to identify the different solutes that make up a sample based on known solutes.

Chromatography

This lesson looks at what is meant by the terms 'solubility' and 'saturated' and factors that can affect this.

Solubility

This lesson looks at how we can investigate solubility, potential sources of error in investigations and identifying ways in which can improve our method.

Solubility Practical

This lesson looks at the scientist Masataka Taketsuru and his introduction of whisky to Japan.

Case Study of Masataka Taketsuru

This lesson reviews the second half of the topic and includes exam-style questions to promote knowledge application.
