On Thursday, December 3rd and 10th, 2015, Project Cornerstone visited 78 second grade students at Hancock Elementary in the San Diego community of Tierrasanta.

Mrs. Hess, Mrs. Doran and Mrs. Gapasin's classes enjoyed learning about the importance of local construction aggregates. 

The class activities began with an introduction to construction aggregates.  Then, the class split into two groups in order to perform a sieve analysis on an aggregate sample.  One group tested a sample that included river sand, while the other group tested a sample with beach sand.  As a class, they figured out which sample would be best for making concrete.  The students were then able to make their own concrete.  Using silicone molds, the students made concrete owls, penguins, footballs, bugs and much more.

The students were excited to do some hand-on science.  One student exclaimed, "this isn't play time, or snack time. This is science time!," as she enthusiastically made her way to the concrete making station.
