Stone+wear

9E Building for the future

Stone wear
Explain how the properties of a rock can be linked to its uses as a building material. Describe some properties of each of the three main types of rock, including their reaction with acid. Recall that acids react with metal carbonates to produce a salt, carbon dioxide and water. Explain why rocks are affected differently by physical weathering.

Suggest why freeze-thaw weathering affects different rocks differently. >
 * 1) What are the different types of rock? What do you know about them? Discuss
 * 1) Find out about types of rock on your own. You can use one of more of the resources listed below:
 * 1) Answer Qs1-6 from p62-63 of Exploring Science 9
 * 1) Which types of rock react with acids? What products are formed - [[file:ES9_CHAP_Ec2.pdf|Rocks and acid]] //(follow the teacher guidance on how to write up your outline and results)//
 * 1) Why do certain rocks react with acid and what is happening follow the investigation outline [[file:ES9_CHAP_Ec3.pdf|Carbonates and acids]] to find out //(follow the teacher guidance on how to write up your outline and results)//.
 * 1) Extension: Now apply your knowledge of carbonate by completing [[file:ES9_CHAP_Ec7.pdf|Rocky equations]]. Remember to refer to Drawing effective graphs as needed.
 * 1) Research the physical weathering of rocks. Find out about freeze-thaw weathering using the [|Geological Society].
 * 1) Extension: What is concrete, why is it useful? Find out more by reading [[file:ES9_CHAP_Ec8.pdf|A Concrete solution]] and answering the questions.
