Processing Materials

How raw materials are changed into useful products

From Raw to Useful

Raw materials come from nature — wood from trees, clay from the ground, wool from sheep. We process (change) these materials to make useful products. Processing can include cutting, heating, mixing and shaping.
Example

Examples of Processing

Clay → shaped and baked → brick or pot Wheat → ground into flour → baked → bread Tree → cut into planks → furniture Sand → heated very hot → glass
Note

Remember

Processing changes the form of materials but uses the same raw material. In South Africa we process many materials: gold ore into jewellery, sugarcane into sugar, and maize into mealie meal.
