Instructional Ideas

• Show images of limestone quarries in operation to give the class perspective on their sizes and locations
• Have pairs research a working quarry and collect data about its economic contributions and impact on the local flora and fauna

Classroom Considerations

• The content stands on its own, requiring little prior knowledge of limestone or mining activities

Pros

• The narrator and script bring pupils into the lesson by having them imagine a quarry opening up in their own towns — a great way to connect them to the material
• You can link the video to a study of changes in the earth's land and water features over time, as limestone exists where water was once present

Cons

• None
