Engineering Performance Matrix
Geotechnics concerns the knowledge of the ways in which Earth’s materials (i.e. rock and soil) behave under stresses and strains in order to determine how structures and products interact, or will interact, with their surrounding environments as well as how the Earth’s materials can be used to mitigate, prevent, or solve problems. This concept is important to Engineering Literacy, as it enables one to design the foundations of structures, plan the excavation of build sites, select the route for roads and highways, minimize the negative impacts that structures have on the environment, and prevent the damages caused by natural hazards to make the Earth’s surface more suitable for people and the development of communities.
Performance Goal for High School Learners
I can, when appropriate, draw upon the knowledge of Geotechnics content and practices, such as (a) geological properties and classifications, (b) soil characteristics, (c) bearing capacity, (d) drainage systems, (e) slope stability, (f) erosion control, (g) foundations and retaining walls, and (e) geotechnical field tests and codes, to analyze/model the behavior of Earth’s materials, using the appropriate mathematical equations and conventions, in order to solve problems in a manner that is analytical, predictive, repeatable, and practical.
I can describe the three major groups of rocks (igneous, sedimentary, and metamorphic).
I can identify the basic properties of soils (e.g. weight, porosity, void ratio, permeability, compressibility, shear strength, etc.).
I can explain the formation processes and features of different types of rocks.
I can classify a variety of soils in terms of their properties.
