On Friday, April 17, 2015, Project Cornerstone's Crystal Howard and Alyssa Burley, along with Granite Construction's Gary Nolan, visited two sixth-grade classes and a 5th/6th-grade combination class at William H. Frazier Elementary School in Fallbrook, CA.

The students learned about the importance of construction aggregates in their daily lives and where they are mined locally in their community.

They performed a sieve analysis by testing two aggregate samples.  One included river sand and the other included beach sand.  As expected, the students determined river sand is best suited for making concrete.

Students made small batches of concrete using sand, gravel, cement and water.  They added pigment to give their concrete mixtures color before pouring it into molds to make concrete butterflies, ladybugs, footballs, trucks and more!
