Geotechnical engineers are extremely important in deciding if ANY location has suitable conditions for building a structure. Focusing on reading maps, soil properties, and erosion, second graders are going to help decide where to build structures based on the earth below it!
Before we decide to build anything anywhere, it is important to know what is below the surface of the Earth. Even if a site "looks good" it is important to compare it to another site to see if we indeed have the best choice. See how second graders compared two different sites by taking core samples at each location. Can you see the differences between the two sites? Which site would you choose to build on? Why?
