In the Separation Techniques unit, pupils will build on their knowledge of solutions to learn about methods for separating mixtures, including filtration, evaporation, distillation, and chromatography.

In the Solid, Liquid and Gas States and Changes of State unit, pupils learned to categorise substances into the solid, liquid or gas state and explored particle behaviour during changes of state.

This unit explores the concepts of pure substances, mixtures, and diffusion in liquids and gases. It emphasises accuracy, precision, and the use of appropriate techniques during investigations. The focus is on making predictions and recording reliable observations.

Solutions

{{}} is a piece of technical equipment needed for a particular use.

Why is it crucial to select the appropriate laboratory apparatus when conducting an experiment?

{{}} is the apparatus that supports and protects containers that are balanced on a tripod for heating.

It has straight sides, meaning it can hold a large swirling volume.

It has markings to help gauge the volume of its contents when swirled.

It has a flat base so the contents will settle quickly once swirled.

It has sloped sides so the contents won't splash out when swirled.

What feature of a conical flask makes it particularly useful for swirling to mix its contents?

Match the following laboratory apparatus with the correct unit of measurement they are associated with.

Which of the following measurements would you use a ruler for?

Which of the following is **not** used for measuring the amount of a substance?

A {{}} burner is used to heat substances in a laboratory.

All substances are made up of matter, which has __________ and mass.

When a substance is heated, the force of {{}} between its particles is overcome.

What is the name of the process in which a liquid becomes a gas at the surface of a substance?
