Natural Sciences and Technology Grade 6 Term 2: Matter and Materials Solutions as special mixtures

Topic 3 Solutions as special mixtures Insoluble substances Gr 6 Natural Sciences and Technology – Term 2, Topic 3

Insoluble substances Some solids will NOT form a solution in water – these are called insoluble substances. Examples are: Oil Sand Curry Powder Gr 6 Natural Sciences and Technology – Term 2, Topic 3

Insoluble substances Gr 6 Natural Sciences and Technology – Term 2, Topic 3

Insoluble substances Curry powder settled at the bottom of the glass Curry powder to be added to the water Curry powder mixed with water Water in a glass Teacher explain that curry powder is not soluble in water. Show learners step by step what happens when curry powder is added to water. Gr 6 Natural Sciences and Technology – Term 2, Topic 3
