Mixtures of Materials in Grade 6 Natural Sciences and Technology

Exploring mixtures of materials in Grade 6 Natural Sciences and Technology, students learn about what mixtures are, examples of mixtures including solids and liquids, mixing solids, separating substances, and mixing liquids. The content also discusses the visibility of different substances in mixtures, particle size effects on separation, and the concept of solutions formed by well-mixed materials, providing examples for better understanding.

Presentation Transcript

1. Natural Sciences and Technology Grade 6 Term 2: Matter and Materials Mixtures

2. Topic 2 Mixtures Mixtures of Materials (1) Gr 6 Natural Sciences and Technology Term 2, Topic 2

3. What is a mixture? A mixture consists of at least two or more different materials mixed together. Gr 6 Natural Sciences and Technology Term 2, Topic 2

4. Examples of mixtures A mixture can consist of: Solid substances (e.g. peanuts and raisins) Solid and liquid substances (e.g. cup of coffee) Liquid substances (concentrated cool drink and water) Gr 6 Natural Sciences and Technology Term 2, Topic 2

5. Mixing Solids In some mixtures of solids the different substances are still clearly visible after mixing. What examples can learners provide? peanuts and raisins dried fruit different coloured or types of sweets sugar and cinnamon mix Gr 6 Natural Sciences and Technology Term 2, Topic 2

6. Separating substances in a mixture How can these substances be separated? peanuts and raisins dried fruit different coloured or types of sweets sugar and cinnamon mix Gr 6 Natural Sciences and Technology Term 2, Topic 2

7. Mixing solids The bigger the particles of materials are in the mixture the easier it is to separate them out. e.g. rice and peas The smaller the particles of materials are in the mixture the more difficult it is to separate them out. e.g. sand and sugar Gr 6 Natural Sciences and Technology Term 2, Topic 2

8. Mixing Liquids In certain mixtures, the materials are mixed so well together that we cannot see the different materials after mixing. Such mixtures are called solutions . This happens especially when liquids are mixed. What examples can learners provide? cup of coffee milkshake concentrated cool drink and water custard Gr 6 Natural Sciences and Technology Term 2, Topic 2
