In this lesson, we will learn what makes a substance pure or impure. We will also learn to draw diagrams to represent the particles in pure and impure substances.
Unit Overview: Separating mixtures
- Know that some materials will dissolve in liquid to form a solution, and describe how to recover a substance from a solution
- Use knowledge of solids, liquids and gases to decide how mixtures might be separated, including through filtering, sieving and evaporating
For next step we recommend the unit: States of matter.
In this lesson, we will learn what makes a substance a mixture. We will also learn how to identify mixtures and the benefits of using an alloy over a pure metal.
In this lesson, we will learn what makes a substance a formulation. We will identify some common formulations and investigate what happens when formulations are scaled up or down.
In this lesson we will learn about four ways that mixtures can be separated, including using magnets; evaporation, filtration and sieving.
In this lesson we will learn about how to separate soluble and insoluble solids from water.
In this lesson, we will plan and evaluate a method to separate soil and gravel from river water.
