Arizona Rock Products Association Presentation

Written by Alyssa Burley.

On Wednesday, June 8, 2016, the Arizona Rock Products Association held its convention at San Diego's historic Hotel Del Coronado. 

At the event, Project Cornerstone's executive director, Crystal Howard, along with Hanson Aggregates' Terry Tyson, spoke to the audience about community relations and Project Cornerstone's successful educational and outreach programs.

The crowd asked great questions following the presentation and were highly supportive of Project Cornerstone's mission to educate the public about the importance of local construction aggregates (i.e., sand, gravel and crushed stone) through hands-on learning in Science, Technology, Engineering and Mathematics (STEM).

CTE Teacher Field Trip to RCP Block & Brick

Written by Alyssa Burley.

RCP Block & Brick, a manufacturer of hardscape products and masonry supplies in Southern California, hosted Career Technical Education (CTE) teachers from the Grossmont Union High School District on Wednesday, May 25, 2016.  The field trip was organized by Project Cornerstone who is working with the district's CTE specialist to ensure the construction aggregates and related industries are included in the local CTE programs. 

CTE programs are designed to train high school students to enter the workforce or continue onto college after graduation, with the skills they need to be successful in today's job market.  Through educational paths in manufacturing, transportation, building and construction, engineering and architecture, and others, students graduate with skills that make them ready to enter the workforce.  Project Cornerstone is bridging the gap between high school CTE teachers and the industry in order to ensure there is a skilled workforce interested in the aggregates and related industries in the future.  Currently, most CTE programs do not educate students about the industry.

The field trip began at the RCP Block & Brick corporate offices at the Lemon Grove location.  Kathy Olsen and Craig Finch from RCP Block & Brick introduced the teachers to RCP's history and provided a tour of the offices, retail store, products and displays. 


After the tour at the Lemon Grove location, the group headed down to the Otay manufacturing plant.

The teachers toured the mechanic's shop to learn about the types of transportation jobs available in the construction aggregates and related industries.  The teachers asked questions and learned the skills employers want to see in new hires.

They also met the dispatcher who tracks and coordinates deliveries.


The group toured the building where concrete blocks are manufactured.


At lunch, the group of teachers listened to Matt Pound from Escondido Materials talk about engineering and the industry. 

After lunch, the teachers tested their masonry skills by building a concrete block wall.

Overall, the CTE teachers enjoyed the RCP Block & Brick field trip and each one took something positive away from the tour.

Avocado Elementary In-Class Activity

Written by Alyssa Burley.

On Tuesday, May 24, 2016, Project Cornerstone's Crystal Howard and Alyssa Burley, along with Hanson Aggregates' Eric Inouye visited Ms. Gillis' fourth grade class at Avocado Elementary School in El Cajon, CA.


The students learned about construction aggregates (i.e., sand, gravel and crushed stone) used to product concrete and asphalt products, and how they are used to build our communities' infrastructure.

In small groups, the students tested two aggregates samples using a sieve.  One sample included river sand and the other had beach sand.  They were able to determine river sand is best for making concrete.

Then, the students made their own small batches of concrete.  Each student choose a mold to pour their concrete into.  Once the concrete was hard, they were able to take them home.

Teacher Workshop: The Science and Economics of Concrete

Written by Alyssa Burley.


On Saturday, May 7, 2016, elementary and middle school teachers gathered at the San Diego County Office of Education in Linda Vista for Project Cornerstone's Teacher Workshop: The Science and Economics of Concrete.

The teachers learned about construction aggregates (i.e., sand, gravel and crushed stone), how the ancient Romans transformed concrete into a revolutionary building material, the economics of trade, and the science behind concrete.

Teachers participated in several activities that they can implement in their classrooms. 


Thanks to the generous support of the workshop sponsors, each teacher was given supplies to help them implement the activities in their classrooms.  Each teacher received:

  • Lunch
  • Sieve Analysis Starter Kit
  • Science of Concrete Kit
  • Access to online background materials
  • Sample history and economic-related activities

Career and College Fair at Diego Valley Charter High School

Written by Alyssa Burley.

On April 29, 2016, Project Cornerstone had the pleasure of participating in the Career and College Fair at Diego Valley Charter School in El Cajon, CA.  High school students attended the event to learn about possible career paths and higher education opportunities.

Project Cornerstone's Construction Aggregates booth was highly popular among the students.  Many of them didn't know what construction aggregates were when they first walked up to the booth.  However, by the time they left, they were saying things like, "wow, I never thought about this as a career."  Others commented how they thought "this industry is really cool!"

Students learned about the various careers from heavy equipment operator, to engineers, geologist, lab technicians and more.

Project Cornerstone looks forward to participating in future career and college fairs at Diego Valley Charter.
