Science and Technology/Engineering
Technology/Engineering, Grade 9 or 10
Additional Ideas for Developing Investigations and Learning Experiences and Suggested Extensions to Learning in Technology/Engineering are in Appendix III.
Please note: For grades 6-high school, there are suggested learning activities after each set of learning standards. The numbers in parentheses after each activity refer to the related technology/engineering learning standard(s).
Broad Concept: Various materials, processes, and systems are used to build structures.
|2.1||Distinguish among tension, compression, shear, and torsion, and explain how they relate to the selection of materials in structures.|
|2.2 ||Identify and explain the purposes of common tools and measurement devices used in construction, e.g., spirit level, transit, framing square, plumb bob, spring scale, tape measure, strain gauge, venturi meter, pitot tube.|
|2.3 ||Describe how structures are constructed using a variety of processes and procedures, e.g., welds, bolts, and rivets are used to assemble metal framing materials.|
|2.4 ||Identify and explain the engineering properties of materials used in structures, e.g., elasticity, plasticity, thermal conductivity, density.|
|2.5 ||Differentiate the factors that affect the design and building of structures, such as zoning laws, building codes, and professional standards.|
|2.6 ||Calculate quantitatively the resultant forces for live loads and dead loads.|
Suggested Learning Activities
- Demonstrate the transmission of loads for buildings and other structures. (2.1, 2.2, 2.6)
- Construct a truss and analyze to determine whether the members are in tension, compression, shear, and/or torsion. (2.1, 2.3, 2.4, 2.5)
- Given several types of measuring tools and testing tools, give students a challenge and have them evaluate the effectiveness of a tool for the given challenge. (2.2)
- Construct and test geometric shapes to determine their structural advantages depending on how they are loaded. (2.3, 2.5, 2.6, 2.6)
- Using a chart from the state building code, students should be able to correctly use the stress strain relationship to calculate the floor joist size needed. (2.4, 2.6)
- Design and conduct a test for building materials such as density, strength, thermal conductivity, specific heat, and moisture resistance. (2.4, 2.5)
- Calculate the live load for the second floor of a building and show how that load is distributed to the floor below. (2.5, 2.6, 2.6)
- Identify ways to protect a watershed, e.g., silt barriers, hay bales, maintenance of watershed areas. (2.5)
