What's below the surface? A core sample will tell us!
In order to know where to recommend the TarPul to be built, second graders learned about a technology that geotechnical engineers use. A core sample allows us to see below the surface of the ground and determine the types of soil there.
Second graders used this technology and then performed an earthquake test. As geotechnical engineers they changed the depth of the foundation to see how this impacted the building's ability to stay standing after an earthquake!
