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.
Which technology is really the best? Does it meet all the criteria of the challenge? Second graders are closing out their geotechnical engineering unit, comparing the technologies they designed to prevent wind erosion. Way to go second grade!
