Environmental Education In Action
Project Cornerstone Educates Students about Local Construction Aggregates Industry
Project Cornerstone, Inc. is a San Diego-based grassroots organization dedicated to educating the public about the importance of local construction aggregates (i.e., sand, gravel and crushed stone).
The program aims to teach San Diego County students that local mineral resources, like construction aggregates, are an integral part of their daily lives - the highways they travel on, the schools they attend and the homes they live in. Aggregate is the essential raw material in all public works projects, including buildings, flood control bridges, roads, hospitals and all other infrastructure vital to communities.
The organization offers students a chance to see where sand, gravel and crushed stone are locally mined through a field trip to a local mining operation. While at the mine, students enjoy a hands-on activity designed to teach about the various mineral resources used in building our community’s infrastructure. They will also receive instruction on how mines are reclaimed for reuse in their communities after resource extraction is completed.
If teachers do not have the time to include a field trip, Project Cornerstone also offers in-class visits where the hands-on activity and a short presentation is provided.
The program supports Next Generation Science Standards. The Disciplinary Core Ideas are ESS3-A Natural Resources and ESS3-C Human Impacts on Earth Systems.
Cost: Free; teachers/parents are responsible for transportation costs on field trips
