Mini Car Design Challenge

Created Feb. 7, 2024 by Zach Potter

Mini Car Design Challenge

Using the Design Process, you and a partner will design, document, model, and produce a toy car with interchangeable parts. The design must consist of three parts: body (2), chassis, and wheels (4). Each partner will design their own body for the car but partners must work together to design a single chassis and set of wheels.

Time Frame: 4-6 weeks

Stage 1 - Desired Results

Big Idea(s)
  1. Effective use of the engineering design process to solve problems.
  2. Documentation of the process used to solve the problem.
  3. Use of appropriate tools to take accurate and precise measurements.
  4. Developing a design from conception to prototype.
  5. Use of appropriate modeling software.
  6. Using tolerance to create interchangeable parts.
  7. Statistical and graphical analysis of data.

Essential Questions
  • How can the engineering design process help you to create a better design?
  • How can an engineer communicate an idea and the process of how they came up with that idea?
  • What dimensions on a technical drawing require tolerance notation?
  • What tools should be used to take accurate and precise measurements?
  • How can accurate technical drawing aid in the creation of models and prototypes?
  • How can statistical and graphical analysis be used to describe the relationship between two variables?

Stage 3 - Lesson Learning Targets

Learning Activities: Learning targets are written from the students perspective. I can…These should lead up to answering the Essential Question(s).
  • Identify steps of the engineering design process and the tasks involved with each step.
  • Describe the importance of the design process in creating an effective solution.
  • Use appropriate tools/devices to take and record accurate and precise measurements.
  • Describe an object through dimensional annotation.
  • Create appropriate and accurate technical drawings.
  • Describe the concept of tolerance as it relates to interoperability of parts.
  • Interpret data through statistical and graphical analysis.
  • Create a graphical model to describe the relationship between two variables.
