Pure substances and mixtures

Irene Riquelme Gil
Irene Riquelme Gil

This document provides an overview of a unit on matter and energy for year 6 students. It covers topics on the states of matter, pure substances and mixtures, and types of energy. For mixtures, it defines pure substances and the two types of mixtures - homogeneous and heterogeneous. It describes two types of each - homogeneous mixtures allow the different substances to be seen, while heterogeneous mixtures do not. The document also outlines several common methods to separate mixtures, including filtration, decantation, distillation, and evaporation. Examples are given for each separation method.

UNIT 4 MATTER AND ENERGY YEAR 6
Contents (Matter) SESSION 1 Matter and its properties SESSION 2 The states of matter (Changes of state) SESSION 3 The states of matter (Physical and chemical changes) SESSION 4 Pure substances and mixtures
Contents (Energy) SESSION 5 Types of energy SESSION 6 Energy sources SESSION 7 Thermal and light energies.
3. PURE SUBSTANCES AND MIXTURES SESSION 4
3. Pure substances and mixtures (P叩g. 18) Ma#er g(oups together to create substances. There are 2 t56es of substances: Pure substances Mixtures They are made up of 1 type of component or substance. They are made up of 2 or more types of component or substances.
3. Pure substances and mixtures (P叩g. 18) Pure substances
3. Pure substances and mixtures (P叩g. 18) Mixtures There are 2 types of mixtures: HOMOGENEOUSHETEROGENEOUS We can see the different substances and they can be separated easily. We cant see the different substances but they can also be separated.
3. Pure substances and mixtures (P叩g. 18) Mixtures
3.1 The separation of mixtures (P叩g. 18) There are di鍖erent ways to separate the components of a mix@Are: FILTRATION DECANTATION DISTILLATION EVAPORTION
3.1 The separation of mixtures (P叩g. 18) FILTRATION Separation of: solids (not dissolved) from liquids. Type of mixture: Heterogeneous. We need: 鍖lters. Example: preparing a cup of tea or coffee.
3.1 The separation of mixtures (P叩g. 18) DECANTATION Separation of: substances with different DENSITIES.(the element with the highest density remains at the bottom of the 鍖rst container. Type of mixture: Heterogeneous. We need: two containers. Example: separating sand from water.
3.1 The separation of mixtures (P叩g. 18) DISTILLATION Separation of: 2 liquid substances with different BOILING POINTS. Type of mixture: Homogeneous. We need: heat, a condenser, and recipients. Example: making alcoholic drinks. Video time
3.1 The separation of mixtures (P叩g. 18) EVAPORATION Separation of: solids dissolved in liquids. The liquid turns into steam and the solid is collected from the container. Type of mixture: Homogeneous. We need: heat, a pan. Example: separating salt water.
activities 1. Diagram 2. What is the difference between pure substances and mixtures? And between homogeneous and heterogeneous mixtures? 3. How would you separate the following mixtures? - Rice and water. - Coca Cola and ice cubes. - Sugar and water. - Acetone and water. - Cereal at the bottom of the glass and milk. 2.2, 2.3 PHYSICAL AND CHEMICAL CHANGES (P叩gs. 15, 16, 17)
