Humans have been using stone for building purpose for thousands of years. All over the world, we continue to use many types of stone for the construction of road, bridges, build-ings, and monument. In almost any city or town, you can find a wide variety of building stone. Students study and learn to identify different rocks and minerals as part of Earth science in elementary and middle school, but they usually see only small sample and text-book picture in the classroom. An urban geology field trip can allow students to see and touch much more impressive example of these rocks and minerals while also having an opportunity to discuss other place-based topics related to construction, city planning, and environmental and eco-justice issues. Additionally, a field trip looking at rocks and minerals in building can easily be added as part of another field trip to a particular location in a city or town. An extra stop or two can be made to examine rocks, minerals, and building materials. Downtown areas with large and historic building provide the best opportunities for observing a range of rock and minerals types in compact areas. Cemeteries also provide access to range of rocks types as well as a context foe local history study.
