2. Where do construction materials come from? Talk to your partner to decide what is needed to make each construction material.

3. Glass is made from Brick is made from Steel is made from Concrete is made from Copper is made from Sand Clay Iron ore Carbon Copper ore Water Lime- stone Sand Aggregate

4. What processes are used to make construction materials? Discuss and make sentences about how each material is made.

5. Glass Sand is taken from Brick Clay is taken from Steel Iron ore is Copper Copper ore is Concrete First, cement is made with Limestone Stone is taken from and then it is a quarry heated in a furnace moulded into brick shapes and with carbon purified by using electrolysis. cut to shape. limestone and clay mixed with sand, water and aggregate. heated again with more carbon

6. Where do construction materials come from? Find examples of each construction material in the picture and draw arrows to them.

7. Glass Copper Brick Steel Concrete Limestone

8. How are the construction materials produced? Your completed worksheet should look like this.

9. Limestone Stone is taken from a quarry and then cut to shape. Glass Sand is taken from a quarry and is then heated in a furnace. Steel Iron ore is heated in a furnace with carbon to make this alloy. Brick Clay is taken from a quarry, moulded into brick shapes and then fired in a furnace. Concrete Clay and limestone are heated together to make cement. This is then mixed with sand, aggregate and water. Copper Copper ore (copper oxide) is heated with carbon to extract the copper. Electrolysis is then used to purify the metal.
