In-Class Science Activities with Central Elementary Students

Written by Alyssa Burley.

On Wednesday, September 29, 2015, Project Cornerstone's Crystal Howard and Alyssa Burley visited three 5th-grade classes at Central Elementary in San Diego, CA.

Students learned about construction aggregates (i.e., sand, gravel and crushed stone) and how they are used to build roads, homes and schools in their communities.

The in-class program included a lecture about the local construction aggregates industry and sand shortage, a lab experiment where students analyzed sand samples to determine which type is best for making concrete, and a science project where students were able to make small concrete to take home.


Project Cornerstone will return to Central Elementary on Wednesday, October 7, 2015 to visit two more 5th-grade classes.

2014 California STEM Symposium, San Diego

Written by Alyssa Burley.

Project Cornerstone's Crystal Howard and Alyssa Burley spent two days at the Science, Technology, Engineering and Mathematics (STEM) Symposium at the San Diego Convention Center on September 22 & 23, 2014.

The 2nd Annual California STEM Symposium was presented by the Californians Dedicated to Education Foundation (CDEF), in cooperation with State Superintendent of Public Instruction Tom Torlakson and the Commission on the Status of Women and Girls.

The goal of the symposium was to "bring together 3000 teachers, administrators, students, higher education representatives, program providers, philanthropic representatives and industry representatives to engage them in STEM education by providing strategies and resources for program implementation," according to the CDEF website.

Project Cornerstone members Hanson Aggregates and Robertson's Ready Mix sponsored the Project Cornerstone booth.  As a result of Project Cornerstone's presence at the symposium, 61 people requested more information about the hands-on program we offer.  They felt learning about where construction aggregates are located locally and how they are used to build infrastructure was important and would meet their current curriculum needs and the newly adopted Next Generation Science Standards.

In-Class Activity: Making Concrete Pavers

Written by Alyssa Burley.

Over the last few months, Project Cornerstone staff members have developed hands-on activities designed to teach children about the importance of construction aggregates in their lives, while also supporting the Next Generation Science Standards.

The concrete paver kits have been assembled, tested by future engineers, and are ready for the classroom!

Thank you, Hanson Aggregates, for supplying the aggregate for the kits.

Project Cornerstone Meets with California Regional Environmental Education Community

On Wednesday, May 21, 2014, Project Cornerstone representatives, Crystal Howard, Executive Director, and Alyssa Burley, Director of Marketing and Community Outreach, met with Crystal Howe, a science teacher at Garfield High School and District 9a (San Diego and Imperial Counties) representative with the California Regional Environmental Education Community (CREEC), to discuss Project Cornerstone’s goals and how to best connect with teachers in San Diego County.
