TEDx Event at Greenfield Middle School

Written by Alyssa Burley.

Project Cornerstone hosted two workshops called "The Science and Economics of our Earth's Resources" at the TEDx event hosted by Greenfield Middle School in El Cajon, CA on Saturday, April 16, 2016.

The workshops included a brief history about how the ancient Romans revolutionized the use of concrete to build their cities' infrastructure.  The attendees participated in a trade activity where they learned about the value of a commodity and it increases with trade.  They also made their own concrete projects to take home.
