Core Standards of the Course

Strand 1
Students will investigate career opportunities in engineering & engineering technology.

Standard 1
Identify occupations related to engineering and engineering technology.

Standard 2
Differentiate among different engineering & engineering technology disciplines.

Standard 3
Investigate different forms of occupational training and educational opportunities for careers in engineering and engineering technology.


Strand 2
Students will understand the elements of an organized approach to solving an engineering design problem.

Standard 1
Form a basic design process that can be used to solve an engineering problem.

  1. Identify & define the design problem
  2. Brainstorm solutions
  3. Create models & build a prototype
  4. Test the prototype
  5. Redesign and optimize

Standard 2
In order to better comprehend the engineering design process, students should learn that:

  1. Design problems are seldom presented in a clearly defined form.
  2. The design needs to be continually checked and critiqued, and the ideas of the design must be refined and improved.
  3. Requirements of a design, such as criteria, constraints, and efficiency, sometimes compete with each other.
  4. Engineering design is influenced by personal characteristics, such as creativity, resourcefulness, and the ability to visualize and think abstractly.
  5. The process of engineering design takes in to account a number of factors including safety, reliability, cost, quality control, the environment, manufacturability, maintenance and repair, and human factors.

Strand 3
Students will document the design process and communicate the results of that process using appropriate techniques.

Standard 1
Make accurately proportioned sketches using correct drawing conventions.

  1. Understand and use accepted dimensioning practices for sketches.
  2. Create freehand sketches using paper, pencil, and an eraser which is neat, clear, and smudge-free.

  4. Understand and demonstrate the use of the alphabet of lines.
  5. Use letters and numerals that conform to a Gothic style.
  6. Notes are neat and legible.

Standard 2
Create and utilize an engineering notebook per established conventions.

  1. Entries are sequential and chronological.
  2. Accurate and complete reflection of the progress being recorded.
  3. Sketches or pictures are included where appropriate.
  4. No loose entries or pages.
  5. Each page is dated and witnessed.
  6. Unused spaces are identified, lined out, and initialed.
  7. Errors are not erased or obliterated.
  8. Test data and calculations are included.

Strand 4

Standard 1
Perform basic arithmetic functions using fractions and decimals.

  1. Add
  2. Subtract
  3. Multiply
  4. Divide

  2. Understand and demonstrate the conversion of actual lengths to common technical drawing scales.
  3. Accurately scale drawings using CAD techniques when drawing and plotting.
  4. Record measurements using Cartesian and polar coordinates, as well as absolute and relative distances.

Strand 5
Students will be able to develop orthographic views of a part with the correct dimensions and geometry.

Standard 1
