Hands-On Engineering

Req 6g — Building an Engineering Project

6g.
Building an Engineering Project. Enter a project in a science or engineering fair or similar competition. (This requirement may be met by participation on an engineering competition project team.) Discuss with your counselor what your project demonstrates, the kinds of questions visitors to the fair asked you, and how well you were able to answer their questions.

Science and engineering fairs are where you stop learning about engineering and start doing engineering. You identify a problem, design a solution, build it, test it, and then explain your work to judges and visitors. It is the same process professional engineers follow — just scaled to your level.

Finding a Competition

You have several options for meeting this requirement:

Science and Engineering Fairs

Engineering Competitions

The requirement specifically allows participation on an engineering competition team. Popular options include:

Choosing a Project

If you are entering a science or engineering fair, your project should demonstrate a clear engineering concept. Strong projects share these traits:

Project Ideas

Preparing for Questions

The second part of this requirement focuses on communicating your engineering work. At fairs and competitions, judges and visitors will ask questions to understand what you did and why.

Common Questions and How to Prepare

Question TypeExampleHow to Prepare
Purpose“What problem does your project solve?”Write a clear, one-sentence problem statement
Process“How did you build this?”Be ready to walk through your design steps
Results“What did you find out?”Have data and measurements ready to share
Challenges“What was the hardest part?”Reflect on setbacks and how you overcame them
Improvements“What would you do differently?”Every project has room to improve — be honest
Application“How could this be used in the real world?”Connect your project to real engineering applications

Presentation Skills

Reflecting on the Experience

After the competition, think about what you will discuss with your counselor:

  1. What your project demonstrates — What engineering principle or concept does it show?
  2. Questions visitors asked — Which questions came up most often? Were any unexpected?
  3. How well you answered — Where were you confident? Where did you struggle to explain?
  4. What you learned — Not just about engineering, but about communicating technical ideas to non-experts

Competition Preparation

Get ready to compete
  • Identify a competition or fair to enter and note the registration deadline.
  • Choose or develop your project concept.
  • Follow the competition’s rules for project format, display, and safety.
  • Build and test your project, documenting your process.
  • Prepare a display board or presentation materials.
  • Practice explaining your project in under 2 minutes.
  • Anticipate questions and prepare answers.
  • After the event, reflect on the experience for your counselor discussion.
