Why do geotechnical engineers have to know about soil? Why do they need to know about erosion? These are some important questions that second graders are investigating.
Using a small tray of soil, second graders saw Mrs. Brinza create a flood in a small LEGO village (house, bridge, and school). The effects were devastating! Much of the soil washed away because the water's force was strong enough to do so. As the soil eroded, it was deposited farther downstream. This meant that the bridge and house were about to collapse and that the school had large amounts of soil in front of it that were once not there.
Erosion from both wind and soil are REAL problems geotechnical engineers face as they decide where they can recommend structures to be built.
