Different types of rock can be found in different parts of the country. Limestone, which is also called Portland stone, is used in buildings such as the Bank of England. Rocks are removed from the ground by using explosives or by cutting with saws.

After watching the clip, children could think of other uses of rocks and where they have seen them (eg walls, patios, buildings.) They could look around their school or local environment, identifying where they can see rocks being used for a particular purpose. The children could have a selection of rocks, and start to identify features of the different rocks and sort them into groups. The children could use magnifying glasses to look closely at the rocks and draw their observations. Students could start to suggest uses for the rocks based on some simple features, for example “This rock could be used for a wall because it is strong. This rock could be used for a roof because it is flat and water will run off it.”
