Geotechnical engineers have a very important job! They use their knowledge of soil and erosion to help decide where structures should be built! While they do not build structures, they are great with map skills, fair tests, and and manipulating the earth to make a location ideal to build a structure.
Models not only show us a representation, but they also EXPLAIN something. Second graders have been working on drawing and explaining models of how wind can affect soil. Models can include diagrams with labels, but must also contain evidence. Second graders revised their models after they did an experiment! Check out their awesome work!
