Housing Design Technology

Students use the engineering design process and computer-aided design (CAD) program to create a prototype 2D blueprint and 3D design for a single-family residential house by converting full-size measurements to scale size and scale size measurements to full-size using proportions.

Grades 6–8Engineering

Overview

Students use the engineering design process to design a single-family house. They review the process with a video and a vegetable garden sketch, then draw floor plans in Kami or Google Docs and build a 3D design in Tinkercad or SketchUp, using Realtor.com to find an example house that fits the project criteria. Students convert between full-size and scale measurements using proportions and give each other feedback on their sketches. They then build a physical scale model from balsa wood and glue, with an optional 3D-printed version, and the houses are scored with a rubric.

Lesson Objectives

  • Use Realtor.com to find an example of a single family that fits the criteria of the project.
  • Demonstrate an understanding of the Engineering Design Process while utilizing each stage to successfully complete a team challenge.
  • Use the engineering design process to create a 2D blueprint and 3D design for a single family Housing Design Technology residential house.
  • Use a computer aided design (CAD) program that allows them to design their homes to be 3D printed.
  • Convert full size measurements to scale size and scale size measurements to full size using proportions.
  • Recognize scaled drawings of items as a similar figure to the original item.
  • Create a physical model of home using balsa wood and glue.

  • MS-ETS1-1Define the criteria and constraints of a design problem with sufficient precision to ensure a successful solution, taking into account relevant scientific principles and potential impacts on people and the natural environment that may limit possible solutions.
  • MS-ETS1-2Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.
  • MS-ETS1-3Analyze data from tests to determine similarities and differences among several design solutions to identify the best characteristics of each that can be combined into a new solution to better meet the criteria for success.
  • MS-ETS1-4Develop a model to generate data for iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved.
